APX Mobile Dual-Radio Operation: Feature Operation
2.4.5.3 Gun Lock
• Gun Lock is accessible regardless of which radio is selected.
2.4.5.4 Aux Control
• Aux Control operation can be activated by the radio user, regardless of which radio is selected.

2.4.6
Advanced Unmute Rule
For APX Dual Radio In-Band combinations, when one radio is transmitting voice, the other radio will
automatically mute but can still play tones and Voice Announcement.
For APX Dual Radio Cross-band combinations, customers are given the option of having the other
radio mute or remain unmuted. If the "Cross-Band Mute Option" field is checked in CPS, the other
radio will mute automatically when the Selected Radio transmits voice. Refer to Section
"General," on page 1-1
Band" combinations.
If both radios are on the same trunking talkgroup and the "Talkgroup Mute Option" is set to "Always
Mute" in CPS, the Secondary radio will automatically mute when the Primary radio receives audio.
The Secondary Radio will still play tones and Voice Announcement. If the "Talkgroup Mute Option" is
set to "Never Mute", both radios will play the same audio. Refer to Section
Secondary Radio Talkgroup Mute Operation," on page 3-3
Mute Operation.
2.4.7
Radio Inhibit
Selective Radio Inhibit allows the dispatcher to deny an individual access to the radio system by
sending a Selective Radio Inhibit Command to the radio. In an APX Dual-Radio System, both radios
need to be inhibited or uninhibited together.
• When one radio is inhibited, the other radio shall become uninhibited.
• When both radios are in an inhibited state, and one radio is uninhibited, the other radio shall
become uninhibited.
2.4.8
Over-The-Air Rekeying (OTAR)
Both radios (if equipped) are capable of supporting OTAR. The OTAR System can direct rekeys to
either radio in the Dual-Radio System, one radio at a time. User initiated rekey requests are for the
Selected Radio only. In order to rekey both radios, the user will first initiate a rekey request on the
Selected Radio. Once there is a successful rekey, the user can then change the Selected Radio
using the Radio Swap Button. The user can then initiate a rekey request for the newly Selected
Radio.
Successful OTAR rekeys on conventional channels are associated with tone and display indications.
Successful OTAR rekeys on trunking channels are associated with a tone indication.
2.4.9
Audio
If an audio recorder connects to the control head, then it can only record the transmitting and
receiving audio of the Primary Radio. It cannot record any audio from the Secondary Radio.
If the audio recorder connects to the brick TIB(J600), then it can only record the audio of this radio.
