120 Emergency operation
Standard emergency mode
When you press the emergency key your radio enters
‘emergency mode’, if your radio is programmed in
this way.
When the radio enters emergency mode, it will
automatically send alerts together with your radio unit
ID to the dispatcher. These alerts are usually sent on
a designated emergency channel.
Warning The way your radio behaves in emergency
mode depends on how your radio is programmed.
For further information on what your radio may do in
emergency mode, see
"What happens during an
emergency call?" on page 120 .
What happens during an emergency call?
The exact way your radio behaves when it enters
emergency mode depends on how your radio is
programmed.
The main phases for emergency modes are
summarized below. The length of each phase is
determined when the radio is programmed.
When the emergency key is pressed:
Digital channels: the radio continually sends
emergency alerts to the dispatcher until a
response is received. Details of your location
may also be sent (if this feature is available for
your radio).
The radio alternately transmits and receives
so the dispatcher can hear what is happening
in the vicinity of your radio.
(Emergencies end once this phase is
complete or when you end emergency mode.)
