If your MD recorder fails to operate normally, check the following table. It lists common operating errors and simple
measures which you can take to correct the problem. If it cannot be corrected, or the symptom is not listed, disconnect the
recorder's power cord and contact your authorized YAMAHA dealer or service center for help.
Fault
The unit does not respond to
operations.
It happens that this unit does not work
normally.
Playback is not possible.
Recording is not possible.
The MD cannot be removed when
partially inserted.
Excessive noise.
The remote control does not operate.
To clean the cabinet
Use a soft cloth slightly moistened with mild detergent solution.
Care of MDs
• Do not expose the MD to direct sunlight or heat sources such as hot air ducts, nor leave it in a car parked in direct sunlight
as there can be a considerable rise in temperature inside the car.
• Periodically remove dust and debris from the cartridge surface by wiping it with a dry cloth.
• Because the MD itself is housed in a cartridge, you can handle it normally without being concerned about dirt or
fingerprints. However, malfunctioning may result if the cartridge itself is dirty or warped.
Do not open the shutter on the MD cartridge
Trying to force the shutter open will damage the shutter.
