6. If the calibration is successful the display will show Cal in the

center line and end in the lower line and automatically advance

to the compass display.

7. If the calibration was unsuccessful, an err message will appear

in the lower line of the display, and you will need to repeat the

calibration sequence.

8. If you have chosen to set a magnetic declination, adjust the

degrees and direction using the s1 and s2 keys. Set and advance

from variable to variable using the s4 key.

9. If you do not know the Magnetic Declination for your area, leave

this setting at zero.

10. When you have completely entered the magnetic declination, exit

the calibration sequence using the s5 key.

MagnetiC deClination

A magnetic compass points to the earth’s magnetic north pole. Depending on your location, this may

be different from True North. Adjusting the MagnetiC deClination allows you to compensate for

this variation. Magnetic Declination for an area can be found on topographical maps. Declination can

change over time and distance. Make sure the source for your declination settings is up to date. The

following websites are good sources for finding local Magnetic Declination.
