Care and maintenance
To remove dust from the cabinet of the Nº31, use a feather duster. To
remove dirt and fingerprints, we recommend isopropyl alcohol
applied to a soft cloth. Don’t apply water, dusting sprays, solvents,
abrasives, or cleaning fluids directly to the cabinet.
Make sure that the Remote sensor window on the front panel and the
Remote Control’s projection lens are kept clean and dust-free.
Fluorescent lighting and sunlight may interfere with the operation of
the Remote Control. Avoid placing the Nº31 near fluorescent lamps or
in direct sunlight.
When the Remote Control’s batteries need to be replaced, use only
AA batteries; always replace both batteries at the same time. If you
don’t plan to use the Remote Control often, remove the batteries.
When not used for an extended period, even "leak-proof" batteries
can leak corrosive acids that will damage the Remote Control (and
will void the warranty).
A CD, handled carefully, will last indefinitely. A warped, dusty, or
scratched CD can cause playback problems or may sound noisy.
Handle a CD by the outer edges only; if necessary, support it with your
index finger at the center hole. Don’t touch the bottom (unprinted)
side of the CD, and never apply stickers, labels, or adhesive-backed
rings to either side of the CD.
If a CD becomes dirty, use a silicone-treated cloth (like those made for
cleaning camera lenses) or a special CD cleaning kit. Don’t use
solvents, anti-static fluids, or cleaners made for cleaning phonograph
records.
When you’re finished playing a CD, always return it to its plastic case.
Store your CDs where they won’t be exposed to direct sunlight, high
humidity, or extremely high or low temperatures.
