Emergency in TMO
Overview
Please check with your Service Provider for the configuration
of your terminal.
Your terminal may be configured with one of the following:
Emergency Group Call
The terminal will enter Emergency Mode when you press
and hold the Emergency button.
The Emergency Mode allows you to use the
PTT to transmit
with Emergency priority (by either initiating an Emergency
Group Call or requesting emergency transmit priority).
After entering Emergency Mode, you may send an
Emergency Alarm (if configured) and then start the
Emergency Group Call and activate Hot Microphone (if
configured).
The
Emergency Alarm is a special Status message sent to
the infrastructure before the Emergency Group Call starts.
The terminal may wait for infrastructure acknowledge for this
Alarm and attempt retries. Each time you press the
Emergency button, the terminal will send an Emergency
Alarm.
Hot Mic (Hot Microphone) allows you to talk without pressing
the PTT . Pressing PTT during Hot Mic ends Hot Mic
transmission. Pressing the End soft key ends Hot Mic
activity. If Hot Mic is disabled, then use PTT to talk.
Emergency Private Call (half-duplex or full-duplex)
The terminal will start an Emergency Private Call to a pre-
defined ID when you press and hold the Emergency button.
If an Emergency Private Call gets modified to an Emergency
Group Call, the terminal will enter Emergency Mode and will
leave the Emergency Mode when the call ends.
