Alerting User 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 
Emergency Operation on page 66 for details.
Note: At this point the Man Down features is complete. Use 
normal Emergency procedures to cancel Emergency 
transmissions.
Alerting User When Man Down Enhanced is 
Triggered
Note: This feature is to be preprogrammed specifically to a 
zone and channel which supports Emergency feature. 
The volume and repetition duration of Man Down 
Enhanced alert tone could be customized and 
preprogrammed to suite the required situation.
Consult your agent or qualified technician for more 
details.
When the radio initiates Man Down Enhanced, you hear the 
Critical Man Down Continuous alert tone from the radio 
speaker. The volume of this tone is preprogrammed to a 
minimum level or to the current radio speaker level. Whichever 
louder is applied. This can act as a beacon to find the radio. 
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 
alert tone can be heard from the radio speaker.
Once the alert tone is active, changing to another channel with 
different setup triggers different response from the radio.
• To a channel without Emergency feature – The alert tone 
is inhibited.
