User's Guide

When and where to use: The intercom feature allows one control head user to talk to another control
head user in a MCH configuration. At any given time, when a control head being operated has priority
for the intercom call, all other control heads are blocked until the active control head releases PTT
button.
Procedure:
1 Press the Menu Select button directly below Intc to activate the intercom feature of any of the
control heads.
2 Press the PTT button to initiate an intercom transmission.
All control heads that are attached will receive the same intercom call. The display of the control
heads receiving the intercom call shows the alias/ID number of the transmitting control head.
3 Press or the Menu Select button directly below Exit to deactivate the intercom feature.
The intercom feature also deactivates when you initiate a mode change. If the radio is on an
emergency channel, pressing of the Emergency button or the emergency footswitch button on
any control head also deactivates the intercom feature.

system.

the radio shows a FATAL error Extra CH on the display of all attached control heads.
The active control head commands the system normally while the inactive control head is in remote
mode with its display shows Remote.

keys, and Data button, the Emergency footswitch and VIP inputs remain active on the inactive control
head, while all other controls are disabled.
