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
