WARNING
The ALFA is intended to be a backup device and must not be relied upon as your primary means of maintaining altitude awareness. Use the ALFA at your own risk
Altimeters may give erroneous readings if you are tumbling or the altimeter is in a burble (wake). Chest mount altimeters are more vulnerable to this problem
compared to hand/wrist mounted altimeters. If you are in doubt about how this limitation affects your skydiving, consult a licensed instructor
DO NOT use this equipment unless you are currently participating in, or have successfully passed, an approved skydiving course
Please read ALL instructions carefully prior to use
The ALFA must be switched ON prior to entering the airplane
