TrueMagnetic Compass is More Than 5 Degrees Off:

As any magnetic compass the TrueMagnetic compass is disturbed by magnetic fields.

Since the internal electronics and batteries can generate magnetic fields inside the Multi-

Navigator you must calibrate (autodeviate) the compass to compensate for these

disturbances. Calibrate it at least every time you change batteries.

After Calibrating the Compass it is Still off From North:

Check the local magnetic variation (declination) normally indicated on the map of your

area. If you are unsure of the magnetic variation select AUTO. The TrueMagnetic

compass function will calculate the size and direction of the magnetic variation needed

using the current GPS position. Also check to see if the meridians on your map are

referring to Geographic North, Magnetic North or the local grid system as the North

reference system. Select the North reference as the one used on your map.
