The numbers (#

2-Wire Intercom
Step 1. If using a 2-wire intercom, plug it into the base station at #3 or #5, depending on whether a male or female
connection is required.
Step 2. Depending on whether you are using a Clear-Com® or RTS® compatible 2-wire intercom system, position
the CLEAR-COM / RTS TW button (#1) as follows:
In position = RTS® Mode Out position = Clear-Com® Mode
Step 3. If you selected RTS TW, position the RTS CHANNEL select button (#2) to the desired channel as follows:
Out position = Channel 1 In position = Channel 2
Step 4. Press the 2W/4W button (#25) on the front panel of the base station. The 2W and 4W lights (#15) above the
button should go on. Turn the Beltpac power on. Press the IC button on the Beltpac pressed and speak into
the headset microphone. You will hear a delayed echo of your voice. Adjust the NULL control (#4) with a
small screwdriver while you are speaking, until the echo is eliminated.
4-Wire Intercom
Step 1. If using only a 4-wire intercom, plug it into the 4-WIRE connector (#6).
Step 2. Press the 4W ONLY button (#26). The 4W light (#15) above the button should go on.
Step 3. Adjust the 4-wire intercom send and receive levels with the SND and RCV controls (#16).

4-WIRE connector are as follows: Pins 1, 2, 7 & 8 = N/C
Pin 3 = Intercom Out +
Pin 4 = Intercom In +
Pin 5 = Intercom In –

NOTE: If no 2-wire intercom will be used, you must
press the 4W ONLY button (#26), or a squeal will be
heard in the headsets.
