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 Amplifier 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 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 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 Authorized 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 behavior.
TROUBLESHOOTING
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 trouble
persists after checking the following, please contact your dealer or
nearest Marantz distributor.
The amplifier does not operate and the indicators do not
light.
1. Check to see if the power cord is inserted properly into the power
outlet.
The indicators light but the amplifier does not operate.
1. Check to see if the SELECTOR switches and VOLUME control are
properly set.
Sound is heard from only one of the speakers.
1. Check to see if the BALANCE control is properly set.
2. Switch the power of the unit to OFF, and change the connections of
the left and right speaker cords. If the sound from the same speaker
is still not heard, its connection cord or the speaker itself may be
defective.
Considerable hum noise is heard when the turntable is played.
1. Check to see if the plugs from the turntable are properly connected
to the PHONO jacks.
2. Connect the grounding wire of the turntable to the GND terminal on
the rear panel of this unit. If it has already been connected, try
removing it.
3. Check to make sure that the phono cartridge is attached securely to
the tone arm.
4. Unplug the power cord and plug it in again after inverting the
orientation of the blades.
What happens when the SOURCE DIRECT switch is pressed:
The audio signal from the program source is directed to the bypass
circuit, which sends the signal through the minimum required circuit
length to minimize signal degradation in the signal path.
Therefore, when the
SOURCE DIRECT switch is pressed, the signals
from the TAPE and CD-R/MD jacks are not output to the speakers or
headphones.
To output the tape deck or CD-R (MD) signals, the
SOURCE DIRECT
switch should be set to OFF.
Remote control operation is not possible.
1. Is the remote control unit's (RC8000PM) transmitter pointed correctly
at the remote sensor on the front of the Amplifier (PM6010OSE)?
Or, is there an obstruction between the transmitter and the remote
sensor?
2. Are the batteries in the remote control unit (RC8000PM) exhausted?
3. Is there another strong light (from a window, etc.) striking the
Amplifier (PM6010OSE) remote sensor?
4. Is an Audio RCA cord connected to the " REMOTE CONTROL IN " jack
on the Amplifier (PM6010OSE) rear panel?
