Note: If you press LIGHT while calibrating your compass (except

after installing/replacing batteries), the compass does not store

the calibration setting and the original setting is unchanged.

USING THE COMPASS

The 8 displayed cardinal points for this compass are N, NE, E, SE,

S, SW, W, and NW.

Distortion Detection

When DIST appears, the compass is detecting magnetic

interference that compromises its accuracy. Distortion occurs

when there has been a significant change in the surrounding

magnetic fields, such as when you are driving under an overpass,

or over a bridge. The steel in these structures causes inaccurate

readings in any magnetic compass, but unlike other compasses,

this compass detects interference and alerts you.

DIST appears continuously, recalibrate your compass (see

“Calibrating the Compass” on Page 4).

Turning the Compass On and Off

Press POWER to turn the compass on and off. Or, you can press

LIGHT to turn on the compass and the backlight.

To turn off the compass and the backlight, press

POWER.

Important: The compass automatically turns off after about 10

minutes to conserve power if no significant changes occur in the

surrounding magnetic fields.
