TROUBLESHOOTING

Whenever you have a problem with the amplifier, check the follow-

ing points before requesting service. What may seem to be a serious

malfunction is often the result of a simple operational error. If you

still have problems, contact your original dealer or write directly to

your nearest service provider as listed on the Marantz Authorised

Service Station list.

The amplifier does not operate and indicators do not light.

1. Check to see if the power cord is correctly inserted into a power

outlet.

Indicators light, but the amplifier does not operate.

1. Check the SELECTOR and VOLUME settings.

2. Check to see if the supplied connecting pins are correctly in-

serted into the PROCESSOR IN/OUT jacks.

Sound is being produced by only one speaker.

1. Check the BALANCE setting.

2. Turn off the amplifier and switch the connections of the left and

right speaker cords. If the same speaker still does not produce

sound, it probably means that the connection cord or the speaker

itself is defective.

Considerable humming is produced when playing from a

turntable.

1. Check to see if the plugs from the turntable are properly con-

nected to the amplifier’s PHONO jacks.

2. Connect the turntable’s ground wire to the GND terminal on the

rear panel of the amplifier. If the ground wire is already

connected, try disconnecting it.

3. Check to make sure that the turntable’s phono cartridge is se-

curely attached to the tone arm.

4. Unplug the amplifier’s power cord, turn over the plug so the two

blades go into opposite holes, and plug it back in.

Cannot perform remote operation.

1. Make sure the remote control unit’s (RC8000PM) transmitter is

pointed directly as the amplifier’s remote sensor when you per-

form a remote control unit operation.

2. Check for obstructions between the remote control unit’s trans-

mitter and the amplifier’s remote sensor.

3. Check the batteries of the remote control unit.

4. Make sure there is no strong light (from a window or other source)

shining on the amplifier’s remote sensor.

5. Check to see if there is an RCA cord connected to the REMOTE

CONTROL IN jack on the amplifier’s rear panel.

CARE AND MAINTENANCE

This section describes care and maintenance that you must per-

form in order to make sure your Marantz amplifier performs at the

level for which it is designed. Be sure to unplug the amplifier from

the mains supply before any care and maintenance.

NORMAL CLEANING

The exterior of your amplifier will last indefinitely with proper care

and cleaning. For normal cleaning, wipe exterior surfaces with a

soft, lint-free cloth.

IMPORTANT:

Any of the following will mar the finish of your amplifier and should

never be used for cleaning.

— Scouring pads, steel wool, abrasive powders

— Harsh chemical agents (such as a lye solution)

— Alcohol, thinners, benzine, insecticide, or other volatile agents.

SPECIAL CLEANING

Should it amplifier ever become so soiled that normally cleaning is

not enough, use the following procedure for cleaning.

1. Prepare a cleaning solution of one part mild neutral liquid deter-

gent and six parts water.

2. Moisten a soft, lint-free cloth in the cleaning solution and then

wring out all excess moisture from the cloth.

3. Wipe off the amplifier with the damp cloth.

4. Dry the amplifier by wiping it with a soft dry cloth.

REPLACING THE FUSE

(for variable mains voltage version)

Should the fuse blow, immediately unplug the amplifier from the

mains supply. Replace the fuse with a new one of the same type

and rating. If the fuse blows again after the amplifier is turned on,

take the amplifier to an authorized Marantz service provider.

IMPORTANT:

Using a fuse with a higher rating or slower action does not protect

the amplifier and invalidates your warranty.

REPAIRS

Only the most competent and qualified serviced technicians should

be allowed to service this amplifier. Marantz and its factory-trained

warranty personnel have the special knowledge and facilities re-

quired for the repair and calibration of this amplifier. After expira-

tion of the warranty period, repairs can be performed for a separate

charge.

Whenever you experience problems, first try to solve the problem

yourself using the troubleshooting procedures provided on this page.

your nearest service provider as listed on the Marantz Authorised

Service Station list. When you write, be sure to include the model

and serial number of your amplifier, together with a detailed

description of the problem.
