RESETTING THE

SYSTEM

If the system locks up after a power outage, has no display, or has an ab- normal display, reset the system by using a round-headed object, such as a ball-point pen, to press RESET on the back of the system. The STAND BY indicator lights and AM 12:00 flashes on the display.

•Always handle a CD by the edges to avoid fingerprints and always keep it in its protective case or sleeve when it is not in use. Fingerprints and scratches on the CD’s surface can prevent the laser beam from correctly reading the digital information. If the CD gets scratched, use Scratch ’n Fix (RadioShack Cat. No. 42-127).

CD CARE TIPS

Even though a CD is very durable, treat its surface with care. We recom- mend that you:

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

•Do not store CDs in high temperature, high-humidity loca- tions. They might warp.

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

TAPE TIPS

Erasing a Cassette Tape

To erase a previously recorded sec- tion of a tape, simply record over it. To erase the entire cassette tape, let the tape record to the end with no source playing.

You can quickly erase both sides of a cassette tape using a bulk tape eras- er (such as Cat. No. 44-232).
