AAD SERVICE BULLETIN:
Airtec GmbH & Co., maker of the CYPRES 2 automatic activation device, released a service bulletin dated January 31, 2013, that pertains to all CYPRES AADs manufactured from February 2009 through December 2012. Service Bulletin 31012013 instructs all CYPRES 2 users, after the unit is switched on, to check the unit before each jump by pressing the control unit push button one time and watching for the red LED light to flash to ensure the unit is functioning properly. If the LED light does not flash, the user should not jump with the unit, since, as Airtec states, "It is not in a safe working condition, and the unit will not function as intended on a jump." Airtec reports that it "has become aware of a small number of CYPRES 2 units becoming 'non-responsive.' Although the subject units indicated a '0' (or the selected DZ setting) on the display, they were no longer operating." Additional details can be found in the service bulletin.
