6 – Zeroing and Altitude Offset

6.1 Zeroing the ALTITRACK

The ALTITRACK continuously adjusts to the local elevation and the pointer is at the
zero "0" position. If the pointer is not at "0" prior to jumping, the unit has not
adjusted itself to the local elevation and it must be manually zeroed.
Turn the unit OFF and then ON.

6.2 Altitude Offset

If the elevation at the DZ is different from that of the airport of take-off, then adjust
the ALTITRACK before entering the airplane by activating the "Altitude Offset" mode
which is called "ACCESS" :
1. Press Left Front Button and release quickly
2. When "ACCESS" lights, press the button immediately and keep it pressed
3. When "ACCESS" lights again, release the button immediately
