7. Error Display
If any irregularities are detected during selftest, the
Aircrew CYPRES 2 shows a number on the dis-
play. The error code is displayed until the unit is
switched off manually or by the automatic shut off
after 14 hours running-time. During error display
the arming cable is out of function.

or
One or both of the attached release units are
not correctly electrically connected to the
unit. The reason may be a cable break, the
cutter plug could be disconnected, or the re-
lease unit(s) may have activated.
3333
Excessive variations in ambient air pressure
have been measured during the self-test pe-
riod. The unit is unable to obtain consistent
values for the ambient air pressure at ground
level. Possible reasons could be that an at-
tempt to switch CYPRES on has been made
in a car driving uphill or downhill, in an el-
evator or in a ying aircraft.
The switch-on procedure can be performed several
times after a „3333“ error was displayed. If the 0
is displayed, the unit has successfully gone through
the self-test.

After one of these three error displays appears,
the unit switches off. At all following switch ons
the unit will display the error code again and then
switches off. Please discontinue use and send the
unit in for service.
If other error codes appear in the display, if the unit
switches itself off and can not be switched on again,
if the unit does not switch off after 14 hours, if there
is no red light when the button is pressed, or if any-
thing else unusual occurs please record the error
code and contact Airtec or SSK before further use!
Every technical device can fail. So everything imag-
inable can happen with the CYPRES, including, but
not limited to: displaying a status which is not true,
failing to function, or functioning at a wrong mo-
ment or at a wrong occasion. If you or your friends
or family are not willing to accept these uncertain-
ties and risks, then please don’t use CYPRES.
