3 Man Down condition continues for the time
duration defined in the Post-Alert Timer field. Once
the timer expires, the Emergency alarm is
transmitted. The Man Down Clear function is used
in this phase to cancel the Man Down condition.
The following scenarios affect the timers:
• Pressing the PTT button suspends the Man Down
timers; releasing the PTT button re-initiates the
Pre-Alert Timer.
• Pressing other buttons on the radio does not
impact these timers.
• Repositioning the radio exits the Man Down
feature, which stops and resets the timers.
• Pressing a preprogrammed Clear button or
pressing a Menu Select button preprogrammed
for Clear stops and resets the timers. The timers
do not restart until the radio is repositioned.
Note
Emergency must be set up for this feature to
operate. For details on operating the
Emergency alerts, please see

Operation on page 49.
If the radio is preprogrammed to horizontal
only, it must be worn in a vertical position
otherwise the Man Down alert may be
inadvertently triggered.
When the radio is programmed with Man
Down feature, special care is required when
charging the radio with a wall mounted
charger. See
Proper Ways to Handle the
Radio on page 87 for details.
Pre-Alert Timer
This timer sets the amount of time that a Man Down
condition must be present before the radio-user is
warned of the Man Down condition.
When the radio detects that it has returned to the
vertical position or when the radio detects motion, the
Pre-Alert timer stops and is reset.
The Pre-Alert timer reinitiates when the radio detects
it is in the horizontal position or motionless again.
Post-Alert Timer
This timer sets the amount of time the radio needs to
remain in the Man Down condition before the
Emergency alarm is transmitted. When the Post-Alert
Timer is initiated, the radio alerts the user with an
audible tone and displays the “

” text.
