The pressure you select will remain indicated on the display. The adjustment remains
until the unit will be switched off again. If you like to change your input you have to
switch CYPRES off and on again, this is necessary when your drop zone changes
and has a different air pressure.
When trying to set a pressure of less than 200 hPa (approx. 44.000 feet/approx.
13.500 meter ASL), the CYPRES switches itself off after 8 seconds. The display is
blank indicating that the desired adjustment is outside the programmed parameters.
When trying to set a pressure higher than 1050 hPa (approx. -1500 feet / approx. - 500
meter ASL), the counting is reversed until 0, the arrow will point down. This procedure
can be used to have a second 'try' if the correct setting was missed during the
upward counting. The fact that the arrow points down now is not relevant as the
adjusted pressure is the absolute pressure at the DZ.
air pressure at the DZ
location is 720 hPa
