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 unit 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 equip- ment 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 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 should 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 Marantz Authorized Service Center nearest you. In many cases, the dealer where you purchased your Marantz 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.

THE PROTECTION CIRCUIT

If the protection circuit does work, the unit will enter to standby mode and do not only working for 3 seconds.

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:

–power switch turns OFF

–after waiting at least three minutes, power switch turns ON

–re-attempt to operate the equipment

Memory backup

•In case a power outage occurs or the power cord is accidentally unplugged, the unit is equipped with a backup function to prevent memory data such as the preset memory from being erased.

The memory functions are backed up for up to about 2 week.
