THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. THEREFORE IT IS IMPORTANT THAT THE FOLLOWING PRECAUTIONS ARE OBSERVED DURING SERVICING TO PROTECT YOUR EYES AGAINST EXPOSURE TO THE LASER BEAM.

1-WHEN THE CABINET IS REMOVED, THE POWER IS

TURNED ON WITDOUT A COMPACT DISC IN POSITION AND THE PICK-UP IS ON THE OUTER EDGE THE LASER WILL LIGHT FOR SEVERAL SECONDS TO DETECT A DISC. DO NOT LOOK INTO THE PICK-UP LENS.

2-THE LASER POWER OUTPUT OF THE PICK-UP UNIT

AND REPLACEMENT SERVICE PARTS ARE ALL FACTORY PRE-SET BEFORE SHIPMENT. DO NOT ATTEMPT TO RE-ADJUST THE LASER PICKUP UNIT DURING REPLACEMENT OR SERVICING.

3-UNDER NO CIRCUMSTANCES STARE INTO THE PICK-

UP LENS AT ANY TIME.

4-CAUTION-USE OF CONTROLS OR ADJUSTMENTS, OR

PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

WARNINGS (MD)

The AEL (ACCESSIBLE EMMISSION LEVEL) of the laser power output is less than class 1 but the laser component is capable of emitting radiation exceeding the limit for class 1. Therefore it is important that the following precautions are observer during servicing to protect your eyes against exposure to the laser beam.

1) When the unit case cover is removed and LOADING SW (SW 1956) is turned on and then PLAY SW (SW 1954 mechanism PWB) is turned on in a few second.

The laser will light for several second to detect a disk.

2) The laser power output of the pickup unit and replacement service parts are all factory pre-set before shipment.

Do not attempt to re-adjust the laser pick-up unit during

replacement or servicing.

3) Under no circumstances stare into the pickup lens at any time.

4) If laser optical unit becomes faulty, replace the complete laser optical unit.

5) CAUTION-USE of controls or adjustments, or performance of procedures other than those specified herein may result in hazardous radiation exposure.

MINIDISC SYSTEM LIMITATIONS

Even if the maximum recording time of a MiniDisc has not

been reached, "TOC FULL" may be displayed.

Even if the maximum recording time of a MiniDisc has not

been reached, "DISC FULL" may be displayed.

Even if several short tracks are erased, the remaining rec-

ording time may not show an increase.

Two tracks may not be combined in editing.

The total of the recorded time and time remaining on a

disc may not add up to the maximum possible recording

time.

If recorded tracks are fast reversed or fast forwarded, the

sound may skip.

In the MD system, the delimiter of the recording area on an MD is programmed

in a TOC. If partial erasing, recording and editing are repeated several times,

TOC information will fill up, even though the number of tracks has not reached

the limit (255 tracks), and further recording will be impossible. (If you use the all

erase function, this MD can be used from the beginning.)

If there is any flaw on the MiniDisc, that part is automatically excluded from the

space available for recording. Therefore, the recording time becomes shorter.

When the remaining recording time of a disc is displayed, short tracks less than

12 seconds long may not be included in the total.

For MiniDiscs on which repeated recording and editing operations were per-

formed, the COMBINE function may not work.

A track recorded from a CD (digital recording) and a track recorded from a radio

or other equipment (analogue recording) cannot be combined.

A cluster (about 2 seconds) is normally the minimum unit of recording. So, even

if a track is less than 2 seconds long, it will use about 2 seconds of space on

the disc. Therefore, the time actually available for recording may be less than

the remaining time displayed.

If there are scratches on discs, those sections will be automatically avoided (no

recording will be placed in those sections). Therefore, the recording time will be

reduced.

An MD which has been recorded or edited repeatedly may skip during fast reverse

or fast forward.
