Set the Magnetic Declination Angle The angle between magnetic north and the true north direction is called magnetic declination. The earth's magnetic poles fluctuate over time, and it also varies from place to place. Find the magnetic declination on a map or website, and then set the declination on this unit to offset the difference between magnetic north and true north. Please note that if you fail to do this, the readings you get from the compass could be in error. • In COMPASS mode, hold the "COMPASS" button for 3 seconds to enter the compass sensor calibration mode, press "MODE" button to enter setting of the declination angle. The angle will flash on the LCD. For example, below the "0° " will flash on the LCD). • Press "▲"or "▼" to change the angle value, range from -90° to 90°, and press "MODE" button to confirm and exit the setting. ENGLISH I 9

button to enter setting of the
declination angle. The angle will
flash on the LCD. For example,
below the “0° ” will flash on

The angle between magnetic north and the true north direction is called
magnetic declination. The earth’s magnetic poles fluctuate over time, and
it also varies from place to place. Find the magnetic declination on a map
or website, and then set the declination on this unit to offset the difference
between magnetic north and true north. Please note that if you fail to do this,
the readings you get from the compass could be in error.
