In TXI mode, the radio joins group calls for any group that the radio is monitoring, but the transmitting
on that call is still prohibited.
If you initiate an emergency call, the radio immediately leaves TXI mode and attempts to start the
emergency call if the radio is in service.
If the radio is turned off in the transmit inhibit mode, on turning on the radio asks whether to exit the
transmit inhibit mode. If you press the Back touch icon, the radio turns off.

Emergency Operations
Emergency Operations are used in critical situations.
Pressing and holding the Emergency button activates one or more services (depending on your
service provider settings).
When starting Emergency Operations, any ongoing voice call is aborted or cleared down.
During Emergency Operations, the radio rejects phone, PABX, and private calls, and does not monitor
the talkgroups in the selected scan list.
To terminate Emergency Operations, press and hold the Back key.
3.5.1
Emergency Alarm
The Emergency Alarm is a special status message. Your radio sends the message in either TMO or
DMO.
Your radio sends the message each time it enters Emergency Operation. An audible tone sounds for a
successfully sent message. To resend the message, press the Emergency button.
NOTE: During Hot Microphone transmission, your radio is not allowed to resend the message.
3.5.2
Emergency Group Call
The Emergency Group Call has the highest communication priority and it is a pre-emptive call.
Emergency Group Call is available in both TMO and DMO. During Emergency Operations, start
Emergency Group Call by pressing the Emergency button. The radio can also support Hot
Microphone operation, which allows the Emergency Call to be conducted without pressing the PTT
button.
When a radio receives or generates a group call with emergency priority, the display shows the
talkgroup ID and the emergency icon is displayed. A special alert tone is played.
An emergency group call can be configured as:
• A non-tactical call – initiated on a talkgroup preprogrammed by your service provider. When in non-
tactical emergency mode, you cannot switch talkgroups.
• A tactical call – initiated on the currently selected talkgroup.
Pressing the Emergency button during an ongoing emergency broadcast call has no effect. No new
call is started and no emergency alert is sent.
When the Emergency Group Call you participate in terminates, your radio can behave in several ways,
depending on your service provider settings:
• If you are the call initiator, the radio can either stay in the Emergency Mode, or return to TMO.
• If you are not the call initiator, the radio always returns to TMO.
