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
!
