Enabling Secondary Radio Transmission; Figure 3-3. Secondary Radio Talkgroup Mute Operation Configuration - Motorola APX Instruction Manual

3-4
Following are the two selections for Secondary Radio Talkgroup Mute Operation:
1. Never Mute - The Secondary Radio mutes or unmutes according to normal group call
operation, where muting is never forced.
2. Always Mute - The Secondary Radio remains muted when both radios are programmed with
an identical Trunking Talkgroup (based on the Talkgroup ID), and/or Announcement Group
(based on the Announcement Group ID), regardless of which Talkgroup(s) for these radios
are operating in the field. However it can still unmute to individual calls such as Selective or
Private Calls, Call Alerts or Pages, Phone Calls, Alert Tones and Voice Announcements.
NOTE: The Secondary Radio remains muted even when the Primary Radio is not able to unmute due
to its normal unmute rules which are not being satisfied.

Enabling Secondary Radio Transmission

The APX Dual-Radio CPS provides the capability to enable and disable the Secondary Radio
transmission. It allows the Secondary Radio in APX Dual-Radio to transmit on the current channel,
and this feature works on a Radio Wide basis.
When the option is disabled, all transmissions from the Secondary Radio are disabled. Thus, the
radio cannot roam, register and affiliate, but it can still unmute to receive calls. See Section
"Configuring Secondary Radio Talkgroup Mute Operation," on page 3-3
