BEFORE RECORDING

■ Type of recording

Two types of recording are possible: “Digital recording” and “Analogue recording”. There are different cables and connections for each type of recording, depending on the sockets on the equipment being connected to the unit.

(1) Analogue recording

Connect the unit to equipment that has a line output socket, using the cable included with this unit.

●Main equipment: CD player, MD player, radio cassette player, etc.

●Cable required: Connecting cable included with this unit

■ Types of discs

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

● Playback-only MiniDisc:

● Recordable 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).

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 di-

rection 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

back to its original position.

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-

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.
