6. CARE AND MAINTENANCE
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 unit will last indefinitely with proper
care and cleaning. Never use scouring pads, steel wool,
scouring powders or harsh chemical agents (e.g., lye solution),
alcohol, 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
detergent 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.

allowed to service your unit. Marantz and its factory trained
warranty station personnel have the knowledge and special
equipment needed for repair and calibration of this precision
instrument.

of the speaker cable is inserted into the terminal and
that the bare core of the speaker cable is never exposed
outside the terminal.
