over again by switching off then back on.
Once you have made a dropzone offset adjust -
ment, it will be displayed until the jump has been
made, or until CYPRES switches itself off or is
switched off by you.
On landing, CYPRES will accept the new ground
level as its actual „Ground Zero“ reference,
when the preset altitude has been hit precisely
or if the landing elevation is lower than the one
set. This action can be observed by noticing that
immediately after the landing (within a maximum
of 30 seconds), the preset dropzone offset is au -
tomatically replaced by .
It would then be possible to take off from and land
at this location again under canopy without doing
any further adjustment.
But, if you take off at this location and jump into
a dropzone with a different elevation you have to
do another dropzone offset adjustment.
If the landing elevation is higher than set, the unit
will not change to zero display right away. In such
a case, CYPRES must be recalibrated to the correct
Ground Zero by switching it off and on again prior
to the next jump. Do this on the airfield where the
aircraft will take off.
In case you want the same dropzone setting, that
you have used on your last jump to another eleva-
tion: your CYPRES 2 makes it easy for you. It
automatically offers you this value immediately
after the end of the self-test and before it starts to
offer the regular steps. You can choose this setting
again by just releasing the button while you see
its value on the display.
Note:
After a model change, the settings of the chosen
model will be reset to the standard settings (see
Section 14).
Dropzone Offset: It is necessary to do a dropzone
offset adjustment before each individual jump,
whenever the airfield and the dropzone where you
intend to land are at different elevations.
Not doing so can cause injury or death.
