102 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 103 .
Stealth and non-stealth emergency modes
Your radio is programmed to operate in one of
these ways:
■ Stealth : you often work in situations where you do
not want an assailant to know that you have acti-
vated emergency mode. For this reason, the radio
is silent and the display remains
unchanged—there is no indication that the radio
has entered emergency mode.
An optional feature of stealth emergencies is false
powerdown (‘keep alive’). When an unauthorized
person attempts to prevent you from using your
radio by turning it off, the radio
appears to turn off.
However, the radio is still in emergency mode.
■
Non-stealth : you often work in situations where
you want audible and visual confirmation that you
have activated emergency mode (for example, at
an accident scene).
