condition must be present before the radio-user is warned
of the Man Down condition.

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.

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
