GENERAL INSTALLATION NOTES
Mount the intercom stations in locations that are safe and convenient for use.
It is recommended that the master station be mounted inside the cab.
Consider potential background noise that the hands free remote station might
pick up.
If excess background noise is picked up by the hands free remote station due to
vibration, mounting it on a rubber pad can help reduce noise.
Ensure a good ground connection. Isolate the intercom ground wire from other
grounds that can be noisy (strobes, radios, priming motors, etc.).
Make interconnecting cable runs as short as possible.
Secure excess intercom cable in a figure 8 pattern.
The foot switch option requires the installation of a single-pole single-throw
switch (not supplied with intercom).

OPERATION
Basic Two-Way System
The basic two-way intercom system includes a master station with volume and
Push-To-Talk (PTT) controls and a remote station that is operated hands free. The
remote station is always transmitting unless interrupted by a transmission from the
master station.
Basic Three-Way System
The basic three-way system includes two master stations (A and B) with volume
and PTT controls and a remote station that is operated hands free. The remote station
is always transmitting unless interrupted by a transmission from a master station.
Master station A has transmit priority over master station B and the remote station.
System Options
Handheld Microphone ICX01 Option
This option is for installations in high noise areas. The microphone plugs into a
receptacle on the station box. The system can be keyed to transmit with the microphone
switch or the PTT button on the station box.
Foot Switch Option
This option requires the installation of a single-pole single-throw foot switch (not
supplied with intercom). A two conductor cable is wired at the foot switch and
connected at the station box with a 2-pin Molex connector. The system can be keyed
to transmit with the foot switch or the PTT button on the station box.
Remote Station with PTT Button ICX05 Option
This option is for installations where a remote station with hands free operation is
not required. The PTT button will have to be pressed for the remote to transmit.
