Emergency operation 93
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).
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.
