Landing location lower than the take-off location
The m
device must be preset to the negative value for the elevation difference between the take-off and the landing location altitude. The

altitude lock in such cases depends on the landing location, i.e. as per version 450m or 900m, minus the specified altitude difference. In or-
der to provide problem free functioning and take-off detection ability in such cases, the m

seconds, it is possible to even descend lower than the take-off altitude; nevertheless, descending more than -40m below the preset landing
altitude is strongly warned against. Upon landing with the preset altitude, the device will automatically switch off. Switch on the device
prior to the next jump, i.e. at the take-off altitude of the aircraft. This will provide failure free calibration and functioning of the m
