EN For places elsewhere in the world, visit the website: http://www.magnetic-declination.com When you set the declination angle on the compass you compensate for the difference between true and magnetic north. This makes the compass reading more accurate. To set the declination angle: 1. Press DISP/- repeatedly to navigate to compass mode. 2. Press and hold SET. Display will show CALI. 3. Press DISP/- to toggle to declination option. Display will show DECLI. 4. Press SET to confirm. 5. Set the following options: on / off; West / East (only if ON is selected); degree of declination angle by pressing the following buttons: • to increase value or toggle options • DISP/- to decrease value or toggle options • SET to confirm 2. Press and hold SET. Display will show CALI. 3. Press DISP/- to toggle to True North option. Display will show NORTH. 4. Press SET to enter settings. 5.

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.

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 True North calibration:
1. Press
DISP/-
repeatedly to navigate to compass mode.
2. Press and hold
SET
. Display will show CALI.
3. Press
DISP/-
to toggle to True North option. Display will
show NORTH.
4. Press
SET
to enter settings.
5. Press
to select on / off, then press
SET
to
confirm.
If ‘ON’ has been selected, rotate the unit to align direction
indicator to true north when prompted, then press
SET
to
confirm.
NOTE
If the declination angle is turned ON, the True north
function will automatically turn itself OFF and vice-versa.
