SET THE TRUE NORTH CALIBRATION

When you do not know the declination angle, the true north

calibration function can be used to compensate for the

difference between magnetic and true north. All you need

to know is the direction of true north (this can be found from

landmarks in your immediate vicinity). Setting the true north

calibration makes the compass reading more accurate.

To set the true north calibration:

1. In any compass display screen,

press SET until the screen

opposite appears.

2. Press and hold SET to enter

setting mode.

3. Turn the compass to the position

of true north and press SET.

NOTE If the declination function is turned ON, the true

north function is automatically turned OFF and

vice-versa.
