FIELD DEFINITIONS:
Silent Alarm
When enabled, the radio will operate silently when transmitting an emergency signal. No audible or visual
indicators will occur.  This feature is not compatible with Emergency Receive.  To enable Silent Alarm the
Emergency Receive (F4/F3/F6) must be disabled.  Emergency operation must be enabled on the Conventional
Personality screen (F4/F6/F3) and/or the Trunking Personality Emergency Options screen  (F4/F4/F4/F8). In
addition, the Emergency button must be configured from the Radio Wide Button screen  (F4/F3/F3/F2).
Warning
Programming of Silent Emergency provides the user NO indication, visible or
audible, that the emergency has been sent. If you program silent emergency in
conjunction with the Long Press Emergency feature users should be trained to
LONG PRESS the emergency press button for an extended duration to ensure
that the emergency will be sent.
Unmute Option
This feature is an optional ADDITION to the Emergency Silent Alarm feature Enabling this feature will cause the
radio to UNMUTE on the emergency talkgroup (for trunking) or frequency (for conventional) for voice traffic when
the radio is in SILENT ALARM EMERGENCY mode. The Unmute Option will allow the dispatcher to provide
feedback to the person initiating the emergency state via code words, without drawing undesirable attention.    
The factory default is Disabled.
Warning 
Channel Delay (sec)
The radio must be on a channel for this delay time before it can transmit an emergency signal.  For emergency
operation, sometimes this delay time is desired to prevent the radio from sending an emergency signal on an
undesired channel,which might occur while the user is changing channels and pressing the emergency button.
Valid selections are 0 to 7 seconds.  Factory default is 2 seconds.
Man Down Pre-Alert (sec)
This delay is the period between closure of the Man Down switch and the initiation of the Man Down Alert tone.
The radio must have an external Man Down switch for this feature to work.  The Man Down switch is an optional
switch that can be attached to the radio to detect when the radio position is not vertical.  Valid delays are 1 to 120
seconds.  Factory default is 10 seconds.
Man Down Post-Alert (sec)
This delay is the period between the Man Down alert tone and the actual transmission of the Emergency Alarm
sequence.  The radio must have an external Man Down switch for this feature to work.  The Man Down switch is
an optional switch that can be attached to the radio to detect when the radio position is not vertical.  Valid delays
are 1 to 120 seconds.  Factory default is 10 seconds.
