3.4 INTERCOM MODE
The optional intercom mode gives users at multiple control heads connected to
the same radio the ability communicate with each other without transmitting
over-the-air. Turn intercom mode on and off using the “INTERCOM” menu
as follows:
1. Use the c and d buttons to cycle through the available menu items until
“INTERCOM” appears in the display.
2. Use the ◄ or ► buttons to toggle between “On” and “Off.”
When intercom mode is turned on:
• Incoming voice calls will override intercom communications for the
duration of the voice call. The radio and associated control heads will
remain in intercom mode and intercom communications will resume
when the voice call ends.
• “TG: INTERCOM” appears in the control head’s display when talking on
the intercom. This indicates microphone audio is not sent out on the
selected talk group; rather, it remains localized between the radio control
positions (i.e., the control heads connected to the mobile radio).
• If a call exists on the currently selected talk group when a PTT button is
pressed at one of the control heads, “TG: in use” appears in the display to
indicate intercom mic audio cannot preempt the call on the talk group.
CAUTION
A user at a radio with only one control head/front panel
can turn intercom mode on. In this case, pressing the
microphone’s PTT button will not send microphone
audio anywhere.
