APPENDIX “A”

ALTIMETER CALIBRATION

The altimeter is calibrated in factory and usually requires
no calibration. Perform this procedure only if you notice
large differences compared to a reference altimeter.

1. Turn-on the Oblò and press the knob for 1 second to

enter in the function menu. Rotate the knob to select

the “Setup” menu and click to enter.

2. Rotate the knob to select the “Password” menu and

click to enter.

3. Insert the password “590691” by turning the knob to

increase/decrease the digit and press it to go to the

next digit.
The following screen appears:
