Connecting to a Two-Line Phone

To record information about calls received on a two-line 
phone, you can connect two Caller ID boxes using a triplex 
adapter (not supplied, available at RadioShack). Each 
Caller ID box only records information about calls received 
on the line to which it is connected.

Your modular phone wall jack must be an RJ14 jack wired 
for two phone lines. 

1. Disconnect the telephone line cord from the modular 

phone wall jack, and plug it into the 

L1 + L2

 jack on the 

triplex adapter.

2. Plug the triplex adapter into the modular phone wall 

jack.

3. Plug the pre-wired telephone line cord from your Caller 

ID box into either 

L1

 or 

L2

 on the triplex adapter.

4. Repeat Step 3 to connect another Caller ID box to the 

other available jack (

L1

 or 

L2

) on the triplex adapter.

You can set the Caller ID box flat on a desk, shelf or 
table by itself or with the supplied mounting bracket, 
or use the mounting bracket to mount the Caller ID 
box on a wall.

You need two screws (not supplied) with heads 
larger than the keyhole slots in the mounting 
bracket.

1. Using the keyholes in the bracket as a template, 

mark the mounting screw locations on the wall.

2. Drill a hole in the wall at each marked location.

3. Thread the screws into the holes, letting the 

heads extend about 

1

/

8

 inch (3mm) from the 

mounting surface.

4. Attach the mounting bracket to the Caller ID 

box.

5. Align the keyhole slots on the mounting bracket 

with the screws and slide the Caller ID box 
down until it is secure.

6. Lift the Caller ID box’s screen to adjust it to the 

desired angle.

Be sure to set your 
answering machine to 
answer after two or 
more rings, so the 
Caller ID box has time 
to record the call 
information.

1. Plug one end of a third 

telephone line cord into the 
answering machine’s phone 
jack and the other end into the 
phone’s modular jack.

1. Plug the line cord’s 

other end into the 
answering machine’s 
line jack.

1. Plug one end of 

another modular 
cord (not supplied) 
into PHONE JACK.

1. Plug the Caller ID box’s pre-

wired telephone line cord 
into the modular wall jack.

Caller ID box lets you connect up to four 
Caller ID boxes to the same phone line, so 
you can receive Caller ID information on 
more than one phone on that line.

If you are installing one Caller ID box, set

Caller ID box, set

boxes.

 NOTE

• If no keys are pressed for 20 

seconds, the Caller ID box exits 
setup.

• If you install more than one Caller 

ID box on the same phone line 
and do not set M/S on at least 
one Caller ID box to M, incoming 
calls might be disconnected.

• You can also connect other Caller 

ID modules that do not have the 
Call Waiting function to the same 
phone line as your Caller ID box, 
as long as you do not connect 
more than four modules at the 
same time (including this Caller 
ID box).

• If you connect another type of 

CID module (other than this Caller 
ID box) that has Call Waiting to 
the same phone line, the CID 
Waiting signal might be garbled or 
not received.
