Discs to Avoid
The Nº51 Media Player is compatible with 5-inch (12 cm) and
3-inch (8 cm) conventional, round discs. Do not attempt to load
discs with other size and shape characteristics. All discs must align
with one of the circular guides inside the disc drawer.
Disc Care and Handling
Discs require special care and handling to ensure optimal perfor-
mance. Pay particular attention to the following:
DO hold discs at their center hole and outer edges. Take care not to
leave fingerprints, dirt, and scratches on the disc surfaces.
DO load single-sided discs with the label side facing upward and
double-sided discs with the side intended for playback facing
downward. All loaded discs must align with the circular guide inside
the disc drawer.
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,
pencils, or other sharp-tipped writing instruments. Do not glue
paper or attach stickers to discs. Although not as fragile as the
recorded side, damage to the label side of the disc can render the
disc unplayable.
Caution!
The Nº51 is a single-disc player. Do not attempt to insert more
than one disc in the disc drawer at one time. This might cause
damage to the player, the discs, or both.
Dirty or damaged discs might affect playback performance or
damage the player. Do not attempt to load cracked, chipped,
scratched, warped, dirty, or otherwise damaged discs in the disc
drawer.
