Operation of CopperHead 3404 Transceiver System
Intercom
Intercom
The CopperHead 3404 Base Station is delivered pre-configured for compatibility with one
of three standard intercom systems: Clear-Com, RTS, or Four-Wire (matrix). Wiring for each
of these options is described in
Connector Pin Assignments on page 80. The operation of
your specific intercom system is beyond the scope of this User's Guide ( please see the
documentation provided with your intercom or consult your intercom provider).
Intercom controls and indicators are found on the rear of the CopperHead 3404 Camera
Unit and provide the following functionality:
• Headset volume control for two Intercom channels and Program audio.
• Sidetone adjustment to control the volume of the operator's voice heard on the
intercom headset. It does not affect the mic volume on the intercom channel.
• Control of the Push-To-TALK (PTT) function for each Intercom Channel, either locally or
through a remote PTT switch.
• LEDs show audio activity on the two Intercom and Program audio channels.

• LISTEN: To set listening level for an intercom channel or the PROGRAM Audio, adjust
the desired LISTEN control knobs at the top of the Audio Interface box ( Figure 6-1 : #18,
19, 20). The LISTEN indicator LEDs indicate activity on the Intercom channel(s) and the
Program audio feed, and illuminate even if your LISTEN control knobs are turned down.
• TALK: The Intercom TALK toggle switch ( Figure 6-1 , #15) opens the headset
microphone onto Intercom Channel 1, Channel 2 or both channels. This switch does
not control which Intercom audio channel is heard in the headset.
• Momentary Mode: To activate the headset mic, press and hold the TALK toggle
switch (#15) up (for Channel 1) or down (for Channel 2). The corresponding Green
talk LED will remain lit while the TALK switch is held. The microphone is turned off
when the TALK switch is released, and the TALK indicator turns off.
Note: Intercom beltpacks cannot be plugged into the CopperHead 3404
Camera Unit. Only an intercom headset can be plugged into the Camera
Unit.
