1. Function
1.1 Design philosophy
CYPRES 2 (which stands for “CYbernetic Para-
chute RElease System”) is an automatic activa-
tion device that meets all of the needs of today‘s
skydivers.
The device is simple to operate: Switch it on prior
to the first jump of the day when your DZ and
airfield are at the same location and height . You do
not need to switch it off because CYPRES 2 will do
this automatically.
CYPRES 2 will check the weather conditions
continuously during the day by measuring the air
pressure twice a minute. This means that the unit
should always be precisely calibrated to the ambient
air pressure at ground level.
The parameters of the various CYPRES 2 models
have been chosen to meet the needs of the vast
majority of skydivers, without interfering with
routine parachuting operations. Millions of jumps
with CYPRES since 1991 have proven the sound-
ness of these parameters. Certain specific activities
may nevertheless require special considerations or
CYPRES 2 settings. Freefall - or any vertical speed
that is greater than the activation speed at the defined
activation altitude (with an Expert CYPRES 2 this
is set to 35 meters per second/78 mph at sea level)
- will cause CYPRES 2 to activate. The CYPRES
family of AADs is exceptionally reliable. CYPRES
units have saved the lives of well over 5,100 sky-
divers to date and no unit has ever failed to activate
when the appropriate conditions have been met.
CYPRES 2 is truly the most reliable piece of para-
chuting equipment ever produced.
CYPRES 2 cannot open your reserve - it is only
intended to cut your reserve closing loop. CYPRES 2
is strictly a backup device and is not a substitute for
proper training and the timely execution of emergency
procedures. It may show a faulty display or fail at any
time for any reason, potentially causing injury or death.
Do not use CYPRES 2 if you do not accept these risks.
You must ensure that the reserve closing loop passes
through the cutter hole. If you loan, rent or sell your
CYPRES 2 to somebody else it is your responsibility to
communicate this warning to them.
