CARE AND MAINTENANCE
This section describes the care and maintenance tasks that must be performed to optimize the operation of your Marantz equipment.
MAINTENANCE
HEAD CLEANING
If the heads are not cleaned for a long period, dirt or dust may be deposited on the heads and capstans, causing degraded
To prevent this, clean the heads, etc., periodically as follows.
1.Turn the power off.
2.As shown in Figure 10, clean the parts which come in con- tact with tape, including the heads, capstans, tape guides, pinch wheels, etc., with a cotton swab soaked in head clean- ing solution or denatured alchohol.
HEAD DEMAGNETIZATION
When a magnetized metallic objects (such as a screwdriver tip, etc.) comes in contact with a head or capstan, or when the deck has been used for a long period of time, the head may be magnetized and noise may be generated. If the head is extremely magnetized, the high frequencies in recorded tapes could even be erased due to it. To prevent this, demagnetize the heads and capstans periodically (every 20 hours of use) using a
Caution:
Be sure to turn the power of the cassette deck off before using a head demagnetizer.
CLEANING OF EQUIPMENT EXTERNAL SURFACES
The exterior finish of your unit will last indefinitely with proper care and cleaning. Never use scouring pads, steel wool, scour- ing powders or harsh chemical agents (e.g., lye solution), al- cohol, 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
–dilute some washing up liquid in water, in a ratio of one part detergent 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 technicians should be allowed to service your unit. Marantz and its factory trained warranty station personnel have the knowledge and special equipment needed for repair and calibration of this precision instrument.
In the event of difficulty, call the
TROUBLESHOOTING
Should faults occur, it is in many cases not necessary to consult your dealer or technical service department. On the basis of the following checks you will be able to rectify a number of faults yourself without difficulty.
If the fault cannot be remedied after the following check, please consult your dealer or nearest Marantz service agent.
The tape does not travel.
1.Check that the power cord is plugged properly.
2.Check that the POWER switch is set to ON.
3.Check that the tape is rewound.
The tape travels, but no sound is output.
1.Check that the cassette tape is recorded.
2.Check that the mixer, amplifiers and speakers are connected and functioning properly.
Tape will not record.
1.Check that the protection tabs of cassette tape are not broken.
2.Check that the recording level is set properly.
Sound is distorted.
1.Check that the recording level is not too high.
2.Check that the head is not dirty.
Sound is unstable.
1.Check that the head is not dirty.
2.Check that the pinch wheels (capstans) are not dirty.
3.Check that the tape is wound regularly.
Noise is noticeable.
1.Check that the head is not dirty.
2.Check that the head is not magnetized.
3.Check that the DOLBY NR switch is set properly according to the tape.
Hum interferes with the sound.
1.Check that cords are connected properly.
2.Check that there is not any source of magnetism (TV, motor, transformer, etc.) placed near the unit ?
3.When this unit and amplifier are stacked, hum noise is some- times generated depending on the amplifier model. In such a case, place the components in positions where interfer- ence does not occur.
