If you wish, you may calibrate the barometric altimeter manually from „Main Menu > Settings >
Off-road >
Barometer Calibration‟ introducing the present altitude with the keypad that will be
displayed when pressing this option.
In order for this manual calibration not to be altered by the automatic calibration process, you
must set TwoNav to take the altitude by only taking the barometer reading.

Compass calibration
Calibration is a necessary procedure for the directions supplied by the electronic compass to be
correct.
It is an instrument very sensitive to weather and magnetic fields changes, so it has to be re-
calibrated each time it is going to be used in a new area.
Calibration must be carried out in the open air and far from sources of alterations of the magnetic
fields, such as cars, buildings or electric lines.
For more safety, it is recommended to calibrate the compass before each outing.
Once inside the calibration utility, all you have to do is to turn the device slowly on a horizontal
position for a few seconds.
