1 The Talkgroup Lock Feature can be enabled / disabled from a programmable button or 

menu. The radio must be on a P25 Conventional Channel or else the radio will bad 
beep.

2 Talkgroup Select

The current functionality of Talkgroup Select is (TG Lock Disabled)

User is able to direct entry a Talkgroup or select a Talkgroup from a list. The 
selected Talkgroup will permanently replace the selected channel's Talkgroup.

If Direct Entry and the Talkgroup does not exist in the radio’s profile, the 
Talkgroup is replaced and the radio will automatically enable the Override 
Talkgroup Security Settings on the Zone page. The current Override settings will 
be used for that Talkgroup since it doesn't reside the radio’s profile.

For Direct Entry, a valid Talkgroup of 1 - 65535 must be entered, otherwise the 
radio will display Invalid TG and bad beep.

If Talkgroup Lock is Enabled, the Talkgroup Select feature will have new 
functionality.

If Talkgroup is entered via Direct Entry and the talkgroup resides in the Armada 
profile, the radio will store the Talkgroup as the Lock Talkgroup and will exit 
menu mode.

If the Talkgroup is entered via Direct Entry and the Talkgroup does not reside in 
the Armada profile, the radio will display Invalid TG and bad beep.

If the Talkgroup is selected from the list, the radio will store the Talkgroup as the 
Lock Talkgroup and will exit menu mode.

If Talkgroup Lock is enabled, no permanent changes will be made to the selected 
Talkgroup, only the Lock Talkgroup will be affected.

3 Radio will use the key that is assigned to the active TG unless the Override Talkgroup 

Security Settings is active. In that case it will use the security parameters that are 
defined in the Security section on the Channels tab.

4 If Talkgroup Lock is enabled, the radio will only use the Lock Talkgroup for the 

selected channel. The rest of the channels will use the programmed Talkgroup. If this is 
not done, then the radio would only be able to monitor a single TG for all scan 
channels.

5 If Emergency is declared while Talkgroup Lock is active, the radio will use the 

Emergency Talkgroup first if it is defined. If no emergency Talkgroup is defined, it will 
use the Lock Talkgroup.

Standard conventional calls can be placed to other radios monitoring the selected channel. 
The proper coded Call Guard squelch tone or code or P25 NAC may need to be 
transmitted by your radio for them to receive your call (see Sections 5.4 and 5.13.3).
