REPLACING THE DC ADAPTER’S FUSE

If the CD player stops operating, check the fuse in the DC adapter’s cigarette- lighter plug. If it has blown, follow these steps to replace it with a 3-amp, 5 × 20 mm, fast-acting fuse such as Cat. No. 270-1054 (not supplied).

Caution: Using a fuse that does not meet these ratings can damage your CD player or the vehicle’s electrical system.

1.Carefully unscrew the tip of the ciga- rette-lighter plug.

2.Remove the old fuse and replace it with the new fuse.

3.Screw the cigarette-lighter plug’s tip back onto the body.

CD CARE TIPS

Even though a CD is very durable, you should handle it with care.

•Keep the CD inside the CD player or in its protective case or sleeve when you are not playing it.

•Handle a CD by its edges to avoid fingerprints that can prevent the CD player’s laser beam from accurately reading the CD. Your local Ra- dioShack store sells a suitable CD cleaner kit.

•Do not write on either side of the CD, particularly the non-label side. (Signals are read from the non-label side.)

•Keep the CD dry. A water drop can act as a lens and affect the laser beam’s focus.

•Never use chemicals such as record cleaning sprays, anti-static sprays or fluids, benzene or thinner to clean CDs. These chemicals will perma- nently damage the plastic surface of the CD.

•If a CD skips when you try to play it, the CD might be scratched. Your local RadioShack store sells a Scratch ’n Fix kit (Cat. No. 42-127) that might stop the skip. Also see “Troubleshooting” on Page 19.
