Care and Maintenance
To remove dust from the cabinet of the Nº390S, use a feather
duster. To remove dirt and fingerprints, we recommend isopropyl
alcohol and a soft cloth.
Caution! Always apply the isopropyl alcohol to the soft cloth and then
wipe the Nº390S with the dampened cloth. Never pour or spray
even small amounts of any liquid directly on the Nº390S, as
doing so may allow the liquid to reach the circuitry inside the
unit. Any liquid inside the unit poses a hazard to both the user
and to the unit, and must be avoided.
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 Nº390S 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
“leakproof” 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, including audible
skipping or other noises. Handle a CD by the outer edges only; if
necessary, support it with your index finger at the center hole.
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.
