Function of the m
in a pressurized aircraft
2
The m
device can be used in pressurized aircraft providing the conditions below are observed.
2
The ambient atmospheric pressure (outside the aircraft) must be maintained inside the aircraft up to 450 m (1,475 ft) above the aircraft
take-off location for the m
specified altitudes, the device will be unlocked, which will be indicated by the disappearance of the centre line on the control unit. Once the
altitude lock unlocks, the aircraft can be pressurized. The aircraft must not be pressurized to a pressure higher than the ambient atmospheric
pressure adequate for an altitude of 450 m (1,475 ft) or 900 m (2,950 ft). If there are devices present in the aircraft with preset altitude locks
for 450 m (1,475 ft) and 900 m (2,950 ft), the pilot must pressurize the aircraft for ambient atmospheric pressure at 900 m (2,950 ft).
If the specified limits are not observed, the device may fail.
3.5
Altitude Lock
The altitude lock is preset in the device as the fixed value of the altitude above ground at which the device automatically unlocks
to activate the cutter during the aircraft ascent. The cutter activation is enabled only after exceeding this altitude. The device will
be unlocked, which will be indicated by the disappearance of the centre line on the control unit. This is a small but very important
interaction with the user.
Before unlocking:
In the aircraft does not exceed the altitude of the altitude lock, the m
parameters are met. With the aid of the indication of altitude lock release, the user can easily check the correct function of the device in
the aircraft with an altimeter, or the instructor can perform a quick m

Landing in water
The m
device can be used for landing in water, salt or fresh. The processing unit and the control unit, as well as the cutter, are waterproof

to a depth of 2 m (6.5 ft) under the surface for up to 24 hours. The processing unit contains a filter that has to be changed upon contact
with water. If it lands in the water but water doesn't get to the filter, replacement is not necessary. For the procedure of how to replace
the filter, see the Maintenance chapter. We recommend having the filter changed by your rigger. After the filter is replaced, check the
altitude lock release in the aircraft to find ensure the filter is 100% permeable and fully functional.
