SPT12 or more.
- Don't strip the insulation off more than shown in the figure, at
the speaker terminal connection of speaker cable.
Speaker cable (Type SPT12 )
- Connect speakers in correct polarity, according to the indication
for the polarity of speaker terminals.

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, scour-
ing powders or harsh chemical agents (e.g., lye solution), al-
cohol, thinners, benzine, insecticide or other volatile sub-
stances 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.
