Making an Emergency Call
Your radio may be programmed with an emergency call
function.
About Emergency calls
There are two different types of emergency call that may
be programmed for your radio, both of which are
activated using an assigned function key:
■
Selective emergency call (Selcall): Sends an
emergency call sequence to a group or individual.
■
DTMF emergency call: Sends an emergency call
sequence to a telephone or remote device.
When an emergency call has been made, the radio enters
emergency mode and cycles between receiving and
transmitting so that your operator can hear activity near
the radio. For your safety, the radio displays no signs that
an emergency call has been made.
Making an Emergency Call
Note: It is not necessary to change channels to
send an emergency call.
Your radio may be configured to use either a single press
or double keypress to send an emergency call.
Using a Single Keypress
To make an emergency call with a single keypress:
■
Short or long press the assigned function key
(depending on the configuration of your radio).
Using a Double Keypress
To avoid accidental use of the emergency function, the
emergency call may have been programmed with a
Double Keypress Activation option.
The double keypress activation option will have been
programmed to be used with a short or long press.
