The service bulletin states that each affected Cypres 2 must be returned for repair before its next jump. Airtec in Germany and SSK Industries in Ohio are both authorized to perform the necessary changes. Each affected unit will be returned to the owner at no charge, along with a check for $70 to help each owner with the cost of shipping and a reserve repack.
 
More information appears in the company’s service bulletin. The user’s guide includes instructions on how to check the unit’s serial number using its display. In most cases, the serial number is also listed on the packing data card of the harness and container system the unit is installed in.
