CARE AND MAIN TENANCE
This section describes the care and maintenance tasks that must be
performed to optimize the operation of your Marantz equipment.
CLEANING OF EQUIPMENT EXTERNAL
SURFACES
The exterior finish of your PMD800 will last indefinitely with proper care
and cleaning. Never use scouring pads, steel wool, scouring powders
or harsh chemical agents (e.g., lye solution), alxohol, thinners, benzine,
insecticide or other volatile substances as these will mar the finish of the
equipment. Likewise, never use cloths containing chemical substances.
If the equipment gets dirty, wipe the external surfaces with a soft, lint-
free cloth.
If the equipment becomes heavily soiled:
– dilute some washing up liquid in water, in a ratio of one part deter-
gent to six parts water;
– dip a soft, lint free cloth in the solution and wring the cloth out until it
is damp;
– wipe the equipment with the damp cloth;
– dry the equipment by wiping it with a dry cloth.
