Message Priority Interrupt
During a call on the channel, this function allows you
to send a short message which will also interrupt the

Emer Alarm
In case of an emergency, you can use the feature to
ask for help from your companion or control center.
The emergency alarm has the highest priority. You
can make emergency operation even when your
radio is transmitting or receiving.
Caution:
Any of the two situations below will occur
when the emergency alarm initiator exits
the Emergency mode:
●
The initiator presses the programmed
Emergency Off key or Power Off key to
exit the Emergency mode.
●
When exiting this mode in other ways
(as introduced below), the radio can only
exit the emergency alarm on the current
channel temporarily, and will continue
to give the alarm when it returns to
this channel; moreover, when the radio
switches to another channel which is also
designed with the Emergency feature, it
will give an alarm on that channel, too.
The Emergency feature is enabled by your dealer.
