Care And Maintenance; Troubleshooting - Marantz PM-82 User Manual

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 PM-82 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 sub-
stances. 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 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.
FUSE REPLACEMENT
If a fuse blows, unplug the equipment from the mains supply. Replace
the fuse only with a fuse of the same type and rating. Replacing the fuse
with one of a higher rating or a slower action will not protect the
equipment and will invalidate the warranty. If the replacement fuse
blows again after the equipment is turned on, the equipment should be
taken to an authorized service facility.
REPAIRS
Only the most competent and qualified service technicians should be
allowed to service the equipment. The Marantz company and its
factory-trained warranty station personnel have the knowledge and
special facilities needed for repair and calibration of this precision
equipment. After the warranty period has expired, repairs will be
performed for a charge if the equipment can be returned to normal
operation.
In the event of difficulty, refer to your dealer or write directly to the
nearest location to you that is listed on the Marantz Authorised Service
Station list. If writing, please include the model and serial number of the
equipment together with a full description of what you think is abnormal
about the equipment's behaviour.
TROUBLE SHOOTING
In case of trouble or abnormal operation of the unit, check the following
before contacting service personnel. What may seem to be a serious
malfunction is often the result of a simple operation mistake. If the
