General Information  
Prior to beginning the installation of the telephone entry system, we suggest that you become  
familiar with the instructions, illustrations, and wiring guidelines in this manual. This will help  
insure that you installation is performed in an efficient and professional manner.  
The proper installation of the telephone entry panel is an extremely important and integral  
part of the overall access control system. Check all local building ordinances and building  
codes prior to installing this system. Be sure your installation is in compliance with local  
codes.  
When used to control a door or pedestrian gate, try to locate the telephone entry system as  
near as possible to the entry point. The unit should be mounted on a rigid wall to prevent  
excessive shock and vibration from closing doors or gates. Continuous vibration and shock  
from slamming doors or spring-loaded pedestrian gates will damage the circuit board. Under  
no circumstances should the unit be mounted directly to a moving door or gate.  
ADA mounting requirements for door control. The requirements below apply only when  
the telephone entry system is being used to control entry through a public door only. If this  
system is used to control entry through a vehicular gate or private entrance, the dimensions  
noted below do not apply.  
1. If the clear floor space allows only forward approach to the system, the maximum  
high forward reach allowed is 48 inches above grade to the top of the keypad.  
2. If the high forward reach to the system is over an obstruction of greater than 20  
inches but less than 25 inches, the maximum high forward reach allowed is 44 inches  
above grade to the top of the keypad.  
3. If the clear floor space allows parallel approach by a person in a wheelchair, the  
maximum high side reach shall be 54 inches above grade to the top of the keypad.  
4. If the high side reach is over an obstruction of 24 inches or less, the maximum high  
side reach allowed is 46 inches above grade to the top of the keypad.  
When used to control a vehicular gate with an automatic gate operator, the telephone  
entry system must be mounted a minimum of ten (10) feet away from the gate and gate  
operator, or in such a way that a person cannot operate the entry system and/or touch  
the gate or gate operator at the same time.  
Be sure that the system is installed so that it is not directly in the traffic lane. Goose neck  
mounting post and kiosks work well for these type systems. When planning where to locate  
the system, take into consideration traffic lane layouts, turn around lanes for rejected access,  
conduit runs, power availability, etc.  
Environmental factors must also be taken into account. Surface mount units are designed for  
direct outdoor installations, however it is preferable to protect them from direct exposure to  
driven rain or snow whenever possible. Flush mount units must be protected from direct  
exposure to the elements.  
This telephone entry system contains a number of static sensitive components that can be  
damaged or destroyed by static discharges during installation or use. Discharge any static  
prior to removing the circuit board from the lobby panel by touching a proper ground device.  
Instruct the end user to read and follow these instructions. Instruct the end user to  
never let children play with or operate any access control device. This Owner’s  
Manual is the property of the end user and must be left with them when installation is  
complete.

SECTION 1 - INSTALLATION  
Installation of the 1812 Plus Telephone Entry System involves the installation of the hardware and by-  
pass switch, and the wiring of these components.  
If used to control a vehicular gate with an automatic gate operator, the  
telephone entry system must be mounted a minimum of ten (10) feet away  
from the gate and gate operator, or in such a way that a person cannot  
operate the entry system and/or touch the gate or gate operator at the same  
time.  
1.1 Mount the 1812 Plus  
Surface and Wall mount units can be mounted directly to a wall or pilaster or post mounted using a  
DoorKing mounting post (there are several different styles available). Flush mount units are designed  
to be mounted into a pilaster, wall or kiosk. In any case, be sure that the unit is securely mounted  
and is not subject to continuous vibration from closing doors or gates.  
1. Open the cabinet of the 1812 and carefully disconnect the front panel terminal connector  
and the keypad connector. The front panel terminal connector is located in the lower right  
hand corner. The entire connector will come off the board by gently pulling it straight out.  
2. Remove four (4) 6-32 a 1/2 round head screws from each corner of the control board.  
3. Remove the control board from the housing. CAUTION: The control board contains static  
sensitive components. Discharge any static electricity from your hands by touching a  
proper ground device before removing the control board.  
4. Mount the 1812 housing assembly. Make any conduit connections at this time. Be sure  
that the mounting screws do not protrude into the cabinet where they could cause a  
short.  
5. Route wiring into the housing assembly at this time. DO NOT APPLY POWER.  
6. Clean out the back box. Be sure that all dirt, metal or wood debris is removed from the  
back box.  
7. Remove the main terminal wiring connector from the control board by gently pulling it  
straight up. This will make wiring to the main terminal easier.  
8. Install the control board into the back box. Secure the control board with the four (4) 6-32  
x 1/2 screws removed in step 2. CAUTION: The control board contains static sensitive  
components. Discharge any static electricity from your hands by touching a proper  
ground device before installing the control board.  
9. Plug the front panel connector onto the control board pins in the lower right hand corner.  
The red wire goes to the left.1  
10. Plug the keypad connector onto the circuit board plug. The cable points down.  
11. After pre-wiring the main terminal control board connector (see wiring instructions),  
carefully re-install it onto the control board main terminal pins.

1.2 Mount the By-Pass Switch  
The 1812’s by-pass switch provides a method to remove the 1812 from the telephone line and  
reconnect the homeowner’s telephone to the telephone system. The By-Pass switch IS NOT  
optional – it must be installed as part of the 1812 system. All telephone wiring for the 1812  
must pass through the by-pass switch. Wire the by-pass switch per the wiring instructions in  
this manual.  
Mount the by-pass switch in a location that is easily accessible by the homeowner. In case of trouble,  
the homeowner will use the by-pass switch to restore telephone service to their home. If the by-pass  
switch is installed outdoors, it must be installed in a NEMA Type 4 enclosure (not supplied) to protect  
the switch from direct exposure to rain, snow and other elements.

1.4 Telephone Line Wiring  
Be sure to observe electrical safety when working with phone lines. Phone lines carry electricity and  
the ring voltage can deliver a substantial jolt. The best policy is to disconnect the house phone from  
the phone company Network Interface Device (also known as ‘Demarcation Device’) before working  
on the wiring.  
In most residential homes, the phone cable contains four wires; green, red, black, yellow. The green  
and red are twisted to make one pair and the black and yellow are twisted to make another pair (This  
allowed for the addition of a second phone line since telephones use only two wires). Most phone  
lines installed in the U.S. in the second half of the 20th Century have this type of wire. This type of  
wire is now obsolete. All new telephone projects are using Cat5 wire. If you have Cat5 wiring in your  
home, the conversion is simple (see chart).  
The convention for Cat5 wire is as follows:  
Colored pairs match; e.g., WHITE with blue  
mark goes with BLUE with white mark for one  
phone line, etc.  
Modern Wiring  
Cat5e or Cat6  
Old Wiring  
Four Conductor  
Tip 1 = WHITE / Blue Mark  
Green  
Ring 1 = BLUE / White Mark  
Red  
The pairs are used in the order pictured: for  
the first line, you use BLUE, for the second  
line you use ORANGE, etc.  
Tip 2 = WHITE / Orange Mark  
Ring 2 = ORANGE / White Mark  
Black  
Yellow  
Tip 3 = WHITE / Green Mark  
Ring 3 = GREEN / White Mark  
An easy way to remember this is that the  
colors run from the sky to the earth. BLUE sky  
comes first; ORANGE sunset second; GREEN  
grass third; BROWN earth last.  
Tip 4 = WHITE / Brown Mark  
Ring 4 = BROWN / White Mark  
"Tip" and "Ring" are common terms in the telephone service industry referring to the two wires or  
sides of an ordinary telephone line. Tip is the ground side (positive) and Ring is the battery (negative)  
side of a phone circuit. The ground side is common with the central office of the telephone company  
(telco); the battery side carries -48 volts of DC voltage when in an "idle" or "on hook" state.  
Phone Line Polarity. Tip and ring reversal is mostly immaterial, except for special circuits including  
DID (Direct Inward Dialing) trunks, T-1 lines, and ground start lines where the field side ("terminal")  
equipment (a company's PBX switch, for example) can only function correctly with correct tip and ring  
polarity.  
It is extremely important to use the correct type of wire in telephone applications. Since the  
1812 requires phone lines to be run outdoors or in an underground environment, we  
recommend that you use only wire that is rated for direct underground burial. For example,  
use Cat5e Gel Filled (flooded) UV Resistant Direct Burial Cable run in conduit for your 1812  
phone line requirements. Do not use thinly insulated brown-jacketed telephone wire (the type found  
in the walls of a house) for outdoor or underground phone line wiring. Using improper wire can cause  
noise and hum on the phone line. Be sure that phone wire pairs are twisted.  
Phone lines can be run up to 3600 feet, provided that the proper wire size is used. Refer to the chart  
at the top of the next page.

The 1812 Plus system operates on 16.5 VAC. Do not power this device with 24 volt AC power.  
Use the supplied power transformer, 16 VAC, 20 VA (or U.L. listed equivalent) to power the telephone  
entry system. Do not power any other devices (electric strikes, magnetic locks, etc.) from this power  
transformer. For wire runs up to 100 feet, use 18 AWG wire. For wire runs up to 200 feet, use 16  
AWG wire.  
1.6 Surge Suppression and Grounding  
Proper grounding and the use of surge suppressers can significantly reduce the chance of  
component failure because of static charges or surges. To be effective, ground connections should  
be made with a minimum 12 AWG wire to a ground point within 10 feet of the device being protected.  
The ground point must be at an electrical panel, a metallic cold water pipe that runs in the earth, or a  
grounding rod driven at least 10 feet into the soil. A gooseneck mounting post anchored in  
concrete does not make a good ground.  
It is highly recommended that telephone line surge suppresser (DoorKing p/n 1877-010) be installed  
to help protect the system from phone line power surges.  
It is highly recommended that a low voltage surge suppresser (DoorKing p/n 1878-010) be installed to  
help protect the telephone entry system from power surges.

Mount the by-pass switch in a location that is easily accessible by the homeowner. The By-  
Pass switch IS NOT optional – it must be installed as part of the 1812 system. If  
installed outdoors, be sure to protect the by-pass switch from direct exposure to rain, snow  
and other elements.  
Locate the telephone company demarcation device.  
A
IMPORTANT! Identify the wires that connect to the  
homeowner’s telephones. Disconnect these wires from  
the demarcation device and connect them to terminals 7  
and 8 on the by-pass switch.

2
Use only twisted pair telephone wire that is rated for direct underground burial. DO NOT use  
wire that is intended for indoor applications. Recommend Cat5e Gel Filled (flooded)  
UV Resistant Direct Burial Cable in conduit. DO NOT run telephone wires and high  
voltage wires in the same conduit. Check the phone wire chart for wire size / distance.  
Connect a twisted-pair telephone wire to terminals 1 and 2  
on the by-pass switch. Connect the other end of these  
wires to the telephone company demarcation device where  
you removed the wires from above.  
Check for polarity on the phone "IN" wires, terminals 1 and 2. Terminal 2 must be positive  
with respect to terminal 1. Set a VOM meter to measure DC volts. Place the positive lead on  
terminal 2 and the negative lead on terminal 1. If the meter shows a positive voltage - OK. If  
the meter shows a negative voltage (needle moves off scale to the left), reverse the wires on  
terminals 1 and 2.  
Place the by-pass switch in the “BY-PASS” position until  
the 1812 unit is installed. Test the homeowner’s telephone.  
They should have dial tone while the switch is in the BY-  
PASS position.  
3
Optional DoorKing Surge Suppresser P/N 1877-010 (or  
equivalent) highly recommended.  
Use supplied 16.5 VAC, 20 VA power transformer or UL Listed equivalent. DO NOT  
Power this device with a 24 Volt transformer or source voltage.  
B

For best protection, surge suppresser ground wire must be  
3-ft. or less in length. Use minimum 12 AWG wire.  
Magnetic locks or electric strikes must be powered from a separate UL Listed power  
transformer. Do not power strikes or magnetic locks from the 1812 power transformer.  
3
Ring is Positive with respect to Tip terminal. See  
Use minimum 18 AWG wire for runs up to 100 feet; 16 AWG wire for runs up to 200 feet. It is

SECTION 2 – PROGRAMMING  
Before You Start  
The 1812 has been programmed at the factory with many of the programming parameters already set  
(default setting) for a typical residential application with a single 1812. There is no need to reprogram  
these parameters unless you want to change them. For easy reference, refer to the chart on the next  
page that list the various programming functions and their default settings.  
Important! You MUST program a Master Code before any of the programming steps in Section 2  
can be started. Be sure to write down the Master Code that you programmed as it will be required for  
all programming steps in this Section.  
Programming the Master Code  
This programming step sets the system MASTER CODE. The master code is the four-digit number  
required to gain access to the system memory. The master code can only be programmed from  
the system keypad.  
Default setting is NONE. You MUST program a Master Code.  
1. Open the cabinet of the telephone entry system and press the master code button. The  
Blinking LED next to the button will turn ON.  
Note: After you press the master code push button, the LED will turn ON indicating that  
you are in the master code programming sequence. If a master code is not entered  
within 10 seconds, the master code program sequence will automatically end and the  
LED will return to a blinking state indicating that you have exited the master code  
programming sequence.  
2. Enter a four-digit master code then press *. [ _ _ _ _ * (beep)] (The LED will revert to  
Blinking).  
3. Close the cabinet.

Page 23  
 
2.2 System Parameter Programming  
2.2.1 Phone / Intercom Mode  
Default setting is 1 (Phone Mode).  
The 1812 is normally connected in series with a resident’s incoming phone line, which supplies a  
constant source of DC voltage. When the 1812 is connected in this manner, program the unit for  
PHONE mode.  
If the 1812 is to be connected to an open C.O. (Central Office) port on a key type telephone system,  
or if the 1812 is connected directly to a telephone without a C.O. line, program the unit for  
INTERCOM mode. When programmed in intercom mode, the 1812 will supply the constant DC  
voltage necessary for operation and will disconnect the PH-IN terminals from the circuit since these  
are not used in intercom mode.  
If the 1812 is programmed for the intercom mode, the call forwarding and preprogrammed dial-out  
phone number features will not work.

2.2.13 Set Call Forwarding Microphone Gain and Speaker Volume  
Default setting is 71.  
This adjustment is required only if call forwarding in the 1812 is being used. This step will adjust the  
microphone gain (the remote handset loudness) and the speaker volume (the 1812 loudness) during  
call forwarding operation. You may have to perform these steps several times to get the optimal  
microphone gain and speaker volume adjustment.  
Be sure that you have a call forward phone number programmed (2.5.3) and call forwarding is turned  
on (2.5.2).  
Before making any adjustments, do a test call as the programmed defaults may work fine for you and  
no additional adjustments may be necessary. If adjustments are made, you will need to do a call  
forward test call after each adjustment to determine if the result is to your liking.  
The valid values for both the microphone gain and speaker volume are 0 through 9. These values  
are entered as a two-digit number in step 2 below. The first digit is the microphone gain; the second  
digit is the speaker volume. The default setting is 71, which means that the microphone gain is set to  
7 and the speaker volume is set to 1. A higher value increases the loudness where as a lower value  
decreases the loudness.

2. Push the "Push To Call" button to place a call to the resident. While they are talking,  
adjust the speaker volume potentiometer for adequate sound. To increase the volume  
rotate the potentiometer clockwise, to decrease the volume rotate the potentiometer  
counter clockwise.  
Microphone Gain  
The microphone gain potentiometer is labeled MIC VOL on the control board. This adjustment  
increases or decreases the loudness in the telephone handset in the house.  
1. Open the front of the telephone entry system and locate the Mic Vol adjustment.  
2. Push the "Push To Call" button to place a call to the resident. After they answer, adjust

SECTION 4 – USER INSTRUCTIONS  
4.1 Resident Operating Instructions  
4.1.1 Granting or Denying a Guest Access  
To place a call from the 1812 to the resident’s house, the guest simply presses the PUSH TO CALL  
button located on the faceplate. Once the guest has been identified by voice communication, the  
resident may grant them access by pressing the appropriate tone open number, or they may deny  
access by simply hanging up.  
1. To grant access to a guest, press the programmed tone open number. (The factory  
setting for the tone open number is 9, however this can be programmed to any number  
desired. See section 2.2.8 to program tone open numbers.) The 1812 will respond with a  
confirming tone and will open the door or gate.  
2. To deny access, hang up the telephone.  
Prior to ringing the resident’s phones, the 1812 will perform several logic steps to check the status of  
the Do Not Disturb (DND) and Call Forwarding features.  
If the DND feature is turned on, the DND schedule will be checked. If the current time is within the  
DND schedule, the system will not ring the resident’s phones or call forward.  
If the call forwarding feature is turned off, the 1812 will always ring the resident phones when the  
Push To Call button is pressed. If the call forwarding feature is turned on and the current time does  
not fall within the call forward schedule boundaries, the system will ring the resident’s phone when  
Push To Call is pressed. If the call forwarding schedule is turned on and the current time is within the  
call forwarding schedule boundaries, the system will dial the preprogrammed call forwarding number.  
4.1.2 Call Waiting  
When the resident is on their telephone and a guest pushes the Push To Call push button, the 1812  
will sound a short tone in the resident’s handset. This indicates to the resident that a guest is at their  
door or gate.  
1. To place the outside call on HOLD and talk to the guest, press #.  
2. To grant the guest access, press the programmed tone open number. The 1812 will  
respond with a confirming tone, open the door or gate, and will reconnect the resident’s  
phone with their outside call.  
3. To deny the guest access, press #. The 1812 will disconnect from the resident’s phone  
and reconnect it to the outside call.  
The same process can be used when the resident is talking to a guest at the 1812 and an outside call  
comes in. The resident can place the guest on hold and switch to the outside call.

To use the dial-out phone number feature, the guest simply presses a two-digit directory code (24-50)  
on the system keypad. The 1812 will automatically dial out the phone number programmed under the  
directory code that was entered on the keypad (section 2.3.1). Once the call is answered, the person  
called may grant access by pressing the programmed tone open number or they can press the hang  
up number (2.2.10) to disconnect the call without granting access.  
4.1.4 Access Codes  
The access codes will operate either relay 1 or relay 2 depending on which relay they have been  
programmed to activate (section 2.4.1 and 2.4.2). Access codes may also be time zone restricted  
(section 2.5.6). To use an access code, you must press the # key first. When a valid access code is  
entered, a long tone will sound indicating that the relay has activated.  
1. Press # then enter the access code [# _ _ _ _ _ (beeeeeep)]  
When the access code is entered on the keypad, the system will check its memory to see if the code  
is programmed to activate relay 1 or relay 2, and will also check any time zone restrictions that may  
have been programmed for the specific code that was entered.  
If the access code is a temporary code, the system will check the clock/calendar to determine if the  
current day falls within the programmed temporary access code boundaries (section 2.4.5).

SECTION 5 – MAINTENANCE  
The DoorKing 1812 telephone entry system is essentially a maintenance free device. When the unit  
is properly installed, it should provide years of trouble free service. Maintenance is limited to updating  
the access codes and temporary access codes on an as needed basis.  
The faceplate of the unit should be cleaned on a regular basis to keep contaminants in the air from  
sticking to the surface and possibly causing pitting. When cleaning the faceplate of the system, never  
use an abrasive cleaner or cloth. Stainless steel cleaner works very well with a soft cloth for systems  
with a stainless steel faceplate. A clean damp soft cloth should be used to clean gold plated  
faceplates.  
5.1  
Troubleshooting  
If problems should develop with your telephone entry system, refer to the trouble-shooting guide on  
the following pages to try and correct any problems. Our experience has shown that a majority of  
reported problems are actually programming related and can be corrected on site. If problems persist  
and they cannot be corrected, contact your authorized DoorKing dealer for assistance. Before  
performing any troubleshooting, check the following:  
1.  
2.  
Have a good VOM meter handy to check voltages and continuity.  
Have a telephone test set (DoorKing p/n 1800-050 or equivalent) to check the  
telephone line. Noise on the phone line will cause problems with the entry system.  
3.  
4.  
5.  
6.  
Check the polarity of the phone lines. See section 5.2.  
Be sure that the entry system case is properly grounded.  
Be sure that the telephone wires are twisted.  
A hum on the system indicates that the phone line or 16 VAC power lines may be  
grounded. Check to be sure that the phone lines or power lines are not shorted to  
ground. Be sure that the cable used for communication is a twisted pair, good quality  
phone cable insulated for direct underground burial. Using phone wire that is  
designed for indoor use only can absorb moisture and cause a hum on your phone  
line.  
7.  
Check the 16 VAC system power. Be sure that the transformer is properly rated (20  
VA). Keep the wire run from the transformer to the entry system as short as possible.  
Use 16 or 18 AWG, 600 volt insulated wire only. The importance of proper power  
wiring cannot be over stressed!

Example: set a VOM meter to measure DC volts.  
Place the positive lead on 1812 terminal 2 and the  
negative lead on 1812 terminal 1. If the meter shows  
a positive voltage - OK. If the meter shows a negative  
voltage (needle moves off scale to the left), reverse  
the wires. Repeat this process to check other wire  
pairs on bypass switch and 1812 terminal strip.

5.3  
Isolating Noise Problems  
If noise or hum is present on the resident’s phone line after installation of the 1812 telephone  
intercom system, use the procedure on the next page to find and correct the source of the noise. This  
procedure will require the use of a telephone test set (DoorKing p/n 1800-050 or equivalent).  
Typically, noise is usually introduced into the system because of incorrect wiring, poor quality of wire,  
wire runs exceeding maximum distances, phone and high voltage power wires running in the same  
conduit or in very close proximity to each other, a wrong type transformer was substituted, or the  
phone lines, power lines or 1812 circuit board is grounded.  
1. Place the BYPASS switch in the BYPASS mode (slide switch to right). If noise goes  
away, problem is with phone in/out wiring, power wiring, or 1812 unit. Place the BYPASS  
switch in the ENTRY SYSTEM mode (slide switch to left) and proceed to step 3. If noise  
is still present when switch is in the bypass mode, disconnect C.O. wires and HOUSE  
wires from bypass switch. Connect the C.O. wires to the HOUSE wires. If the noise goes  
away, the bypass switch is bad and needs to be replaced. If noise is still present, contact  
the telephone company for service.  
2. Remove all external items connected to the 1812 unit, such as back-up batteries, relay  
connections, push button switches, or time clocks. All terminals should be free of any  
wiring except terminals 1 and 2 (PHON IN WIRES), terminal 3 (CASE GROUND WIRE),  
terminals 4 and 5 (PHON OUT WIRES), and terminals 17 and 18 (16 VAC POWER  
WIRES). If noise is still present, proceed to step 2. If noise is gone, the source of the  
noise is one of the external devices that were connected to the 1812. Reconnect them  
one at a time until you find the item that is the source of the noise.  
3. Remove the PHON OUT wires from terminals 4 and 5 at the 1812 unit. Connect your  
handy phone directly to the loose PHON OUT wires. The wires should be dead and you  
should not have any dial tone on these wires. If you do have dial tone, the 1812 is wired  
incorrectly. Disconnect power immediately and refer to the wiring information section in  
this manual.  
4. Disconnect your handy phone from the PHON OUT wires (step 3). Remove the PHON  
IN wires from terminals 1 and 2 at the 1812 unit. Connect the PHON IN wires to the  
PHON OUT wires. This completely disconnects the 1812 unit from the circuit. Check the  
phones in the house. If the noise is gone, problem is with or in the 1812 unit, or with the  
power supply or power wiring. Reconnect the PHON IN wires to terminals 1 and 2, and  
the PHON OUT wires to terminals 4 and 5, then proceed to step 5. If the noise is still  
present, problem is with the PHON IN or PHON OUT wires running from the 1812 unit to  
the bypass switch. These wires will need to be replaced and/or re-routed to correct the  
problem.  
5. Disconnect the 16 VAC wires from terminals 17 and 18. If the phone line is now clear,  
the problem is in the 16 VAC power run. Check the power lines for a ground, or running  
next to high voltage wires, or an improper wire size and insulation, or too long of a wire  
run. If noise is still present, go to step 6.  
6. If noise is still present at this step in the trouble shooting sequence, this would indicate a  
short to ground internally in the 1812 unit. Remove the 8-pin front panel terminal strip  
from the circuit board, and check for noise again. If noise is gone, this would indicate a  
problem with the microphone board, speaker, push button, or lights on the front panel  
assembly. Check for any shorts to ground on any of these components or wiring. Check  
to be sure that none of the wires are pinched. If noise is still present, check the wires  
entering the back of the 1812 box and be sure that none are pinched. Be sure that these  
wires are not touching the back of the 1812 circuit board, possibly causing a short to  
ground. If all of the above steps fail to identify the source of noise, contact DoorKing for  
additional assistance.

test phone does not ring, circuit board may be at fault.  
Phones in home ring,  
but no communication  
occurs.  
Check telephone company demarcation (interface) device placement. 1812  
must be wired so that the C.O. wires exiting the demarcation device are  
connected to the C.O. terminals on the bypass switch. Check the wiring  
diagram.  
Disconnect the PHON OUT wires and connect a test telephone to the PHON  
OUT terminals (4 & 5). If the 1812 cannot communicate with the test phone,  
PHON IN and PHON OUT wires may be connected backwards. Check wiring  
and reconnect.
