•
Replace the battery once the self-test has stopped at 8998 or 8999 (voltage too
low), after two years or after 500 jumps, whichever comes first.
•
CYPRES is shielded against radio-transmitter signals. The electromagnetic
shielding has been developed with tremendous input of our effort and has been
investigated thoroughly. Airtec managed to give CYPRES an extraordinary
shielding, but it is impossible to have a 100% protection. We still recommend to
avoid strong radio-transmitters.
•
A release unit that has fired builds up a high internal pressure and will remain
pressurized. Never attempt to open it by force. It can, however, be stored safely
for an indefinite period of time, provided that it has not been damaged.
•
A good reserve pilot chute is an important safety factor. On systems with an
internally-mounted pilot chute, we recommend that owners equip their rigs with
one that has been Airtec tested and subsequently qualified by Airtec and the rig
manufacturer. Typically the rig manufacturer delivers these pilot chutes with the
rig. If there is any doubt, please contact Airtec.

Important notes for the special mode
7.2.1
Important notes for jump pilots
•
If you switch on CYPRES in the airplane the air pressure in cabin has to be
constant during the self-test and the adjustment. If the air pressure fluctuation is
too high, the CYPRES will not function.
•
If the pilot is asked for the air pressure in the cabin on flight level, he has to name
the real, not corrected air pressure.
7.2.2
For the user
•
Battery will last for 300 hours in special mode.
•
Flight or flight and jump can be longer than 1 1/2 hours. There is no restriction in
duration of the flight.
•
CYPRES is immediately at work. It is not necessary to reach a minimum altitude.
•
Special features with absolute pressure measuring instruments being one-sided
evacuated in combination with
α
-rays.
α
-rays have the property to shift the absolute value of this measurement instrument.
The CYPRES can be checked periodically or if required simply: The altitude adjustment
down to 1.072 hPa must be successful, the same down to 1.078 hPa must lead to the
unit switching itself off.
•
Unless an altitude adjustment has been set, CYPRES will not be armed if the
aircraft is exited before it reaches 1500ft (450m) for the Military CYPRES,
3000ft (900m) for the Military Tandem CYPRES and 3500 ft (1100m) for the
Military Bundle CYPRES above the height at which the jumper intends to land.
Once the aircraft has climbed through that altitude and CYPRES has become
fully operational it will work for any exit height.
