■ Types of discs

There are two types of discs: playback-only and recordable discs.

● Playback-only MiniDisc:

This type of MiniDisc usually contains commercially available pre-recorded music. This is the same kind of optical disc as CDs. Playback is performed using an optical pickup. (Recording and editing are not possible.)

There will only be a shutter on one side (the back).

● Recordable MiniDisc:

This is a “raw disc” on which recording can be performed. This is a magnetooptical disc. Recordings are made using a laser and a modulated magnetic field. Repeated recording is possible.

Shutters can be seen on both sides of this type of disc.

■ To prevent recorded discs from being erased accidentally

Slide the accidental erase prevention tab, located on the side of the disc, in the direction indicated by the arrow.

● The disc will then be protected against accidental erasure.

● To add a recording to such a disc, slide the accidental erase prevention tab

Protected against accidental erasure

Notes:

● When making important recordings, it is recommended that you use the AC adaptor. A fully charged rechargeable battery should be loaded into the unit. Then, even if a power failure occurs, the power source will switch over to the rechargeable battery automatically.

● When using the rechargeable battery or the alkaline batteries, if the headphones volume level is set to “0", the bat-

back to its original position.

tery consumption will be less than when listening to the recording whilst it is being made.

● Insert each plug firmly. If the connections are poor, the recording may not be made properly. Always keep the plugs clean. If the plugs are dirty, electrical noise may be recorded.

RECORDING USING THE CABLE INCLUDED WITH THE UNIT

■ Recording from CDs or MDs (Synchro recording)

● Synchro recording is a method that detects the playback sound from the source

equipment. When sound is present, it automatically starts the recording. When the source is silent, the recording will be paused.

Recordings can not be made in the following situations:

● Recording on a playback-only MiniDisc (commercially available music)

● If a Minidisc is protected against accidental erasure (page 12)

About the recording level:

● If the recording level is too low, the playback sound volume may be too low to hear well. If it is too high, the playback sound may be greatly distorted. Since digitally recorded CDs have a large dynamic range (the volume can vary tremendously from very soft to extremely loud), do not set the recording level any higher than is necessary.

Precautions when recording:

● Do not jar or bump the main unit whilst recording. Otherwise, the recording may be unusable.

To interrupt recording:

Press the 38 button whilst recording.

● The unit will enter the recording standby mode.

● To resume recording, press the 38 button again. The track number will be increased by one each time you interrupt a recording.

● Depending on the strength and type of playback signal in the original recording, the new recording may not begin or pause at the correct point when in the synchro mode. If this happens, try making a manual recording.

Precautions when inserting a MiniDisc:

● To insert a Minidisc, push on the middle of the edge of the disc whilst holding it parallel to the main unit.

● If any resistance is felt, do not try to force the MiniDisc into the unit. It may cause more problems. If resistance is felt, remove the MiniDisc and try reloading it.

Notes:

● Whenever any button is pressed, the remote control display will light for about 4 seconds.

● The RECORDING button does not light.
