Radio Alerts When Man Down Feature is Triggered
The Man Down alert tone volume is directly related to
the radio's volume. Ensure that the radio's volume is
loud enough so that the user does not miss the Post-
Alert tone.
Note: If the radio is programmed with Silent
Emergency, the radio inhibits the alert tone and visual
alert associated with the emergency feature.
If the radio is programmed in Surveillance Mode, the
radio inhibits all tones and lights on the radio
including the Man Down tones.
Triggering Emergency
When the user does not clear the Man Down
condition and the Post-Alert Timer comes to an end,
Emergency Alarm or call is triggered. The radio sends
emergency message to units within the same
Talkgroup. The radio also sends ID number and GPS
coordinates to dispatcher if these features are
enabled. User can exit Emergency following the
Emergency procedure. See
page 50 for details.
