Sending A Silent Emergency Alarm; Special Considerations For Emergencies - Motorola Astro APX Mobile 05 control head User Manual

Sending a Silent Emergency Alarm

This feature allows you to send an Emergency Alarm to another
radio without any audio or visual indicator.
Upon acknowledgement, your radio's microphone is
automatically activated, allowing you to communicate with the
other radio without pressing the PTT button.
This activated microphone state is also known as "hot mic".
Note: If you press the PTT button during hot mic, and
continue to press it after the hot mic duration expires,
the radio continues to transmit until you release the
PTT button.
Procedure:
1
Press the preprogrammed Emergency button to activate
the silent alarm feature.
2
Press and hold the emergency button until a tone sounds to
exit the silent alarm mode.
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 channel 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, the display shows NO
EMERGENCY 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.
