DISCS TO AVOID

The RT-20 is compatible with 5-inch (12cm) and 3-inch (8cm) con-
ventional, round discs. Do not attempt to load discs with other size
and shape characteristics, such as those shown below. All discs
must align with the circular guide inside the disc drawer.

DISC CARE & HANDLING

Discs require special care and handling to ensure optimal perfor-
mance. All loaded discs must align with the circular guide inside the
disc drawer. Pay particular attention to the items below.
DO hold discs at their center hole and outer edges as shown above.
Take care not to leave fingerprints, dirt, and scratches on the disc
surfaces.
DO load single-sided discs with the label side facing upward.
DO load double-sided discs with the label for the side intended for
playback facing upward.
DO return discs to their cases when not in use. Discs should be
stored in an upright position out of direct sunlight and excessive
heat, humidity, or cold.

DO NOT write on disc labels or surfaces with ballpoint pens, pen-

cils, and other sharp-tipped writing instruments. Do not glue paper
or attach stickers to discs as shown below. Although not as fragile
as the recorded side, damage to the label side of the disc can still
render the disc unplayable.

DO NOT attempt to load cracked, chipped, scratched, warped,

dirty, or otherwise damaged discs in the disc drawer. Dirty or dam-
aged discs might affect playback performance or damage the
RT-20.
