Radio Shack 63-1120 User Manual

Digital Vehicle Compass

63-1120 OWNER’S MANUAL — Please read before using this equipment.

Thank you for purchasing a RadioShack Digital Vehicle C ompass. Your compass conveniently provides accurate heading information inside your vehicle. It incorporates the same magnetic sensor technology that is used in factory-installed vehicle compasses. The compass electronically separates the Earth’s magnetic field from the magnetic fields generated by your vehicle, to provide accurate compass headings.

Automatic Shut-Off — conserves power by turning off the compass about 10 minutes after you park the vehicle when there are no significant changes in the surrounding magnetic fields.

Magnetic Distortion Detection — alerts you when outside magnetic interference is affecting compass accuracy.

INSTALLING BATTERIES

Your compass requires two AAA batteries (not supplied) for power. For the best performance and longest life, we recommend RadioShack batteries. Battery life is about 11 months (based on an average of 8 hours of compass use and 2 hours of backlight use per week).

Cautions:

• Use only fresh batteries of the required size and recommended type.

• Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.

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 y ou 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 c an 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 u se a power sou rce that supplies 12V DC and delivers at least 3 amps. Its center tip must be set

to positive and its plug must fit the compass' jack. Using an adapter that does not meet these specifications could damage the compass or the adapter.

• Always connect the DC adapter to the compass before you connect it to the power source. When you finish, disconnect the adapter from the power source before you disconnect it from the compass.

Note: Since not all vehicles have constant power supplied to the power outlet, two AAA batteries are required to retain the compass calibration settings in memory (although they do not power the compass when vehicle battery power is used).

Insert the barrel plug of the 12V DC adapter (not supplied) into the

DC12V jack on the back of the compass. Then insert the DC plug

into your vehicle’s power outlet.

MOUNTING THE COMPASS

Choose a clean mounting location on the vehicle’s windshield where the compass is at least 5 inches away from any stereo speakers and will not obstruct the driver’s field of view .

Your compass comes with three suction cups for secure mounting.

1. Insert the small ball head of each suction cup into the larger hole on the bottom of the bracket and slide it into the bracket’s smaller hole so it fits tightly.

2. Place the compass in the holder. Note: To remove the compass from the holder, simply s lide it

out.
