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 ST4000 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 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 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.
REPAIRS
Only the most competent and qualified service technicians shoud be
allowed to service your unit. Marantz and its factory trained warranty
station personnel have the knowledge and special equipment needed
for the repair and calibration of this precision instrument.
In the event of difficulty, call the proper toll-free telephone number listed
on the face of the warranty to obtain the name and address of the Marants
Authorized Service Center nearest you. In many cases, the dealer where
you purchased your Marants unit may be equipped to provide service.
Please include the model, serial number of your unit together with a
copy of your purchase receipt and a full description of what you feel is
abnormal in its behaviour.
TROUBLESHOOTING
GENERAL MALFUNCTION
If the equipment malfunctions, this may be because an electrostatic
discharge or AC line interference has corrupted the information in the
equipment memory circuits. Therefore:
– disconnect the plug from the AC line supply
– after waiting at least three minutes, reconnect the plug to the AC line
supply
– re-attempt to operate the equipment
Memory backup
• In case a power outage occurs or the power cord is acci-
dentally unplugged, the ST4000 is equipped with a backup
function to prevent memory data such as the preset memory
from being erased.
The memory funcitons are backed up for up to about one
week.
