If the corrected values are better than the measured values, press the lower button (ENTER) to store the results. If you
press the upper button, no changes will be stored.
Caution: Beware of placing another compass near this device when performing this calibration, because it might affect
the measurement and affects the calibration procedure.
Declination - Set magnetic declination, a constant value that will be added to the heading shown on the display (and to
all position calculations). If the value is marked as E (East), the correction will be positive. When marked as W (West),
the correction will be negative. The magnetic declination is a constant value, depending on your geographical region. It
can be obtained from many sources.
Deviation – Set magnetic deviation, a constant value that will be added to the heading shown on the display (and to all
position calculations). The deviation is a constant value caused by magnetic elements near the navigation device, that
cannot be removed. In most cases it will be set to 0.
Note: The compass heading on the device display (and the data recorded in memory) will use both declination and
deviation coefficients. There is a common rule: declination is a matter of geographical location and deviation is caused
by other equipment. That is why these two coefficients are separated.
