Man-Down Alarm
The Man-Down alarm notifies nearby personnel if the instrument remains motionless for about 30
seconds when it should be moving, indicating a possible worker in distress. If the wireless option is
enabled, alarm notification is also sent to a remote location. During the Warning Time the alarm
beeps 2x per second and asks the user ‘Are You OK?’. If so, the user can acknowledge and stop
the alarm by pressing the Left Key, or simply tilting the instrument briefly. If the Warning Time
expires without acknowledgment, the full Man-Down Alarm of 3x beeps per second begins.

Sensitivity
This sensitivity of motion sensor can be set to Low, Medium or High. Low
sensitivity means fewer alarms and High sensitivity means easier detection of
stopped motion and more chance of an alarm. Use Up or Mode to move up or
down the list, Right to select, and Left to save and exit.
Warning Time
The Warning Time is the amount of time the Man-Down alarm stays on after it
is triggered. The default time is 30s.

intervals (this function cannot be turned off). In the datalog sub-menu, a user
can adjust the interval or clear all data. Press Right to enter the Datalog menu.
