Military CYPRES versions
The Military CYPRES is identified by the green button on the control unit. The button
has the imprint ‘Military’, ‘Tandem’ or ‘Bundle’. All of the Military CYPRES are available
in a Relative or Absolute altitude adjustment configuration, which permits setting of
the DZ elevation (and therefore the activation altitude) relative to either the switch-
on pressure-altitude or a reference pressure value from the DZ. See Chapter 4.4 for
procedures to set the DZ elevation.
The Military CYPRES will activate at approximately 1000 feet above the ground, or
1000 feet above the designated landing elevation. The Military Tandem CYPRES will
activate at 1900 feet and the Military Bundle CYPRES will activate approximately
2500 feet above the ground or the designated landing elevation. Activation occurs
if the jumper’s rate of descent is greater than two-thirds of terminal freefall speed
when passing through the activation altitude.
