When starting Emergency Operations, any ongoing voice call is aborted or cleared down, and any
packet data transfer in progress is aborted. However, the session is kept open.
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 the right SOFT key.
3.5.1
Emergency Alarm
The Emergency Alarm is a special status message sent while starting the Emergency Operations. The
radio sends the message in either TMO or DMO.
Each time the radio enters the Emergency Operation, it sends the Emergency Alarm. When the
Emergency Alarm is sent successfully, the respective audible tone sounds.
In addition, once the radio is in the Emergency Operation on pressing the E
MERGENCY
button, an
additional emergency alarm is sent (exception: during Hot Microphone transmission).
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, Emergency
Group Call can be started by pressing the E
MERGENCY
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 changes color to
red and a red triangle 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.
