OUTSIDE DIMENSIONS
The 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 fi nish of your unit will last indefi nitely with

steel wool, scourging powders or harsh chemical
agents (e.g., lye solution), alcohol, thinner, benzine,
insecticide or other volatile substances as these wil
mar the fi nish of the equipment. Likewise, never
use cloths containing chemical substances. If the
equipment get 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 in the solution and wring the it is
damp.
• wipe the equipment with the damp cloth.
• dry the equipment by wiping it with a dry cloth.
REPAIRS
Only the most competent and qualified service
technicians should be allowed to service the
factory-trained warranty station personnel have
