4. Press the Right Front Button (+) or the Left Front Button (-) to move the pointer to
the DZ altitude. Range: -3,000 ft / -1000 m to +21,000 ft / 6000m.
The selected altitude is displayed on the screen on the rear side of the altimeter as
well.
When adjusting to a negative altitude on the ground, use the inner negative scale
indication or the value displayed on the rear side of the altimeter.
The ALTITRACK exits "Altitude Offset" mode if no button is pressed within 5 seconds.
Note: If the DZ elevation is higher than 3,000 ft / 1000 m from that of the airport of
take-off, then use this procedure:
- The airplane must fly level at the same altitude as that of the DZ.
- At that altitude switch the ALTITRACK OFF and the ON again and let it calibrate to "0"
before continuing climbing.
Note: When performing a manual adjustment of altitude, the ALTITRACK enters "Jump
Mode" and the altitude is stored in the memory for 14 hours if no jump is made.
