OR
press the
or
arrow keys to decrease the low
speed limit. The 'Low Speed' limit may be set between 5 and 100
knots. The default is 10 knots. To disable, decrease the 'Low
Speed' setting to 0. This will default to 'Disabled'. When disabled,
the DZM will transmit GPS data even when stationary and will not
register takeoff and landings.
If the 'Collective Switch' is used to trigger takeoff and landing
information, the 'Low Speed' setting will be automatically set and
cannot be disabled.

Setting automatic GPS transmission for takeoff and landing based on collective
switch position
The DZM 'Collective Switch' feature is used as an alternative to the 'Low Speed' setting for helicopters. As
helicopters are used for hovering, using just the 'Low Speed' setting, takeoffs and landings may be recorded
when the helicopter is still flying.
With a connection to the helicopter's collective switch, the DZM instead records takeoff and landing events based
on the lifting and lowering of the collective plus the helicopter’s speed.
The DZM's collective switch configuration is set based on the normal status of the switch during flight. For
example, if the collective switch is normally open (when the collective is off the floor) during flight, the DZM will
not transmit GPS positions, or will transmit GPS positions at the lower rate (depending on the GPS Tracking
setting), when the switch is closed (collective on the floor). GPS positions will only be transmitted at their
configured rate when the switch is open and the helicopter deemed to be in flight.
If the 'Collective Switch' is used to record takeoff and landing information, the 'Low Speed' setting will be
automatically set and cannot be disabled. Refer to "Setting automatic GPS transmission based on low speed limit"
on page 57 for further information about using the 'Low Speed' setting.
