3. Function
UP-mode
The UP-mode is used when the landing location is higher than the aircraft take-off location. The display shows the
icon. When
using this mode, switch the device on at the aircraft take-off location.
For the correct functioning of the
m
2
, it is necessary to preset the elevation difference between the landing and take-off location altitu-
de. The numeric value of how much higher the skydiver will land compared to aircraft take-off must be entered. In this case, the altitude
lock depends on the landing location, i.e. as per version 450 m (1,475 ft) or 900 m (2,950 feet), plus the specified altitude difference. In
such a case, the
m
2
device requires for the aircraft to immediately ascend up to at least 40m (130 ft) above the take-off location in order to
allow correct start detection,
and to remain above this alti-
tude. Upon reaching and ex-
ceeding this preset altitude of
plus 40 m (130 ft), the aircraft
must remain above this alti-
tude level until the skydiver’s
jump. Upon landing with the
preset altitude, the device au-
tomatically switches off. If you
do not reach the preset altitu-
de, switch the device off ma-
nually. Switch on the device
prior to the next jump. You will
be provided with failure-free
calibration and functioning of
the
m
2
device.
