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?
