General Radio Features
Initiating a Silent Emergency Alarm
1
Press the emergency button to activate the silent alarm feature.
During a silent emergency alarm, there are no display changes,
and the receiver audio mutes so that no indication is given that
an emergency alarm has been sent.
2
To exit the silent alarm mode, press and hold the emergency
button until a tone sounds.
Note: If silent emergency alarm is used with emergency call,
pressing the PTT button exits the silent mode and initiates
the emergency call.
Special Considerations for Emergencies
•
If you press the emergency button while in a mode that has no
emergency capability, a low-pitched tone sounds.
•
If the unit is out of the range of the system and/or the emergency
alarm is not acknowledged, a tone sounds and the display shows
NO ACKNOWLEDGE.
•
If you press the emergency button, then change to a mode that
has no emergency capability, a NO EMERGENCY display alternates
with the mode name display, and a continuous low-pitched tone
sounds until a valid emergency mode is selected or until the
emergency is cancelled.
•
When an emergency is active, changing to another mode where
emergency is enabled (trunked or conventional) causes an
emergency alarm and/or emergency call to be active on the new
mode.
