1.Slide the battery compartment cover in the direction of the OPEN arrow to remove it.

2.Place two AAA batteries in the compartment as indicated by the polarity symbols (+ and –) marked inside.

3.Replace the cover. All the arrows flash. After you install or replace batteries, you must calibrate the compass (see “Calibrating the Compass” on Page 4).

If all the arrows and digits flash, and the backlight turns on when you turn on the compass, replace the batteries or use vehicle battery power (see “Using Vehicle Battery Power”).

Warning: Dispose of old batteries promptly and properly. Do not burn or bury them.

Caution: If you do not plan to use the compass for a month or more, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.

USING VEHICLE BATTERY POWER

This compass is designed to be used with RadioShack’s 12V DC adapter Cat. No. 270-031A (available at your local RadioShack store). Using any other adapter could void the warranty and damage the compass.

You can power the compass from a vehicle’s 12V power source (such as cigarette-lighter socket) using a 12V, 3 amp DC adapter (not supplied, available at your local RadioShack store).

Cautions:

You must use a power source that supplies 12V DC

!and delivers at least 3 amps. Its center tip must be set
