TAKING CARE OF YOUR PDP-300Your PDP-300 is a fine musical instrument, and de-
serves the most careful treatment. Observe the following
points and your PDP-300 will sound and look great for
many years.
1. Never open the case and touch or tamper with the in-
ternal circuitry.
2. Always turn the POWER switch OFF after use, and
cover the instrument with the dust cover provided.
3. Clean the cabinet and keys of your PDP-300 only with
a clean, slightly damp cloth. A neutral cleanser may
be used if desired. Never use abrasive cleansers,
waxes, solvents or chemical dust cloths since these
can dull or damage the finish.
4. Never place any vinyl products on your PDP-300.
Contact with vinyl can cause irreversible damage to
the finish.
5. Install your PDP-300 in a place that is away from di-
rect sunlight, excessive humidity or heat.
6. Never apply excessive force to the controls, connec-
tors or other parts of your PDP-300, and avoid
scratching or bumping it with hard objects.
