Emergency operation 99
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 both stealth and non-stealth
emergency modes are summarized below. The length
of each phase is determined when the radio is
programmed.
When the emergency key is pressed:
See also "Stealth and non-stealth emergency modes"
on page 98 .
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.
(Non-stealth emergencies end once this
phase is complete or when you end
emergency mode.)
Stealth emergencies only: The radio is
inactive, but it can receive special ‘messages’
from the dispatcher so that he or she can hear
what is happening in the vicinity of the radio.
(Stealth emergencies end once this phase is
complete or when you end emergency mode.)
