Maintenance 34
Placement
Set the system up on an even surface away from direct sunlight, high temperatures, high humidity, and excessive vibration. These conditions can damage the cabinet and other components, thereby shortening the unit's service life.
Place it at least 15 cm away from wall surfaces to avoid distortion and unwanted acoustical effects.
Do not place heavy items on the unit.
Voltage
Do not use high voltage power sources. This can overload the unit and cause a fire.
Do not use a DC power source. Check the source carefully when setting the unit up on a ship or other place where DC is used.
AC mains lead protection
Ensure the AC mains lead is connected correctly and not damaged. Poor connection and lead damage can cause fire or electric shock. Do not pull, bend, or place heavy items on the lead.
Grasp the plug firmly when unplugging the AC mains lead. Pulling the AC mains lead can cause electric shock.
Do not handle the plug with wet hands. This can cause electric shock.
Foreign matter
Do not let metal objects fall inside the unit. This can cause electric shock or malfunction.
Do not let liquids get into the unit. This can cause electric shock or malfunction. If this occurs, immediately disconnect the unit from the power supply and contact your dealer.
Do not spray insecticides onto or into the unit. They contain flammable gases which can ignite if sprayed into the unit.
Service
Do not attempt to repair this unit by yourself. If sound is interrupted, indicators fail to light, smoke appears, or any other problem that is not covered in these instructions occurs, contact your dealer or an authorized service center. Electric shock or damage to the unit can occur if the unit is repaired, disassembled or reconstructed by unqualified persons.
Extend operating life by disconnecting the unit from the power source if it is not to be used for a long time.
(For United Kingdom)
("EB" area code model only)

Types of MDs

Prerecorded MDs
These discs are
for playback only.

Recording MDs
Apart from the time limitations, it is possible to record up to 254 tracks on an MD.
Recording on MDs
MDs are different to tapes
MDs give you control over how tracks are recorded and editing functions allow you to change the contents of an MD after recording.
Unlike cassettes, it is not necessary to find an empty portion to record onto. All recordings start from the first available space. The MD fills up and when the disc is full, either because the time limit has been reached or 254 tracks have been recorded, recording is no longer possible. You can use the editing functions to erase and move your recording around within the MD.
Limitations on digital recording
The serial copy management system (SCMS) prevents unlimited recording of digital material.
Digital recordings are of high quality, but to protect the rights of the producer of the original material, it is only possible to make one digital recording of a digital recording. This also applies if you record analog material digitally. That digital recording can be recorded digitally once more, but is blocked after that.
Analog recordings are otherwise unaffected.

Stereo and monaural recording
This unit is capable of recording in stereo and can playback MDs recorded in stereo or monaural.
Monaural recording allows approximately twice the amount of material to be recorded and played back, but sound quality is affected.
Protecting your recordings
Move the switch to open the write protect hole. Close the hole when you want to record or edit the MD again.

Glossary of terms
Analog - This is the method that records and cassettes use to handle sound signals. It is possible to make analog recordings with MDs.
Digital - This is the usual method used by MDs and CDs to carry and record sound signals. Digital recording can be of very high quality.
Editing - This refers to any post-recording changes made to the MD.
Marking - This is the act of adding track marks. It can be done automatically when recording, or it can be done manually during recording or after recording with the editing functions.
TOC - Table of contents. Information stored on the MD about the tracks and times.
Track marks - These marks separate tracks. There can be up to 254 marks on one MD. They can be inserted automatically or manually during recording, and they can be added or removed with the editing functions after recording.
UTOC - User table of contents. This is information the user can edit, such as text and track positions.
The message "UTOC Writing" appears on the display after recording and editing.
Care and storage
Label MDs only as recommended. Extra labels and exposed adhesive can cause malfunctions.
Do not open the shutter, and close it immediately if it accidentally opens. Never touch the disc inside the MD cartridge.
Keep your MDs out of direct sunlight, humid and dusty places, and away from the direct heat of heating appliances.
