SAFETY PRECAUTION OF MD SECTION FOR SERVICE MANUAL
WARNINGS
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 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 pickup 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.

CD-MD3000H/CD-MD3000W
OPERATION MANUAL
Using the Radio Data System (RDS) (CD-MD3000H Only)
RDS is a broadcasting service which a growing number of FM stations provide.
These FM stations send additional signals along with their regular programme
signals. They send their station names, and information about the type of
programme such as sports or music, etc.
When tuned to an RDS
“TP” (Traffic Programme) will appear on the display when the received broadcast carries traffic information, and “TA” (Traffic Announcement) will appear whilst a traffic information is on air.
“EON” will appear whilst the EON (Enhanced Other Networks information) data is broadcast.
“PTYI” (Dynamic PTY Indicator) will appear whilst the Dynamic PTY station is
received.
“RT” (Radio Text) will appear whilst the unit receives the Radio text data.
“CT” (Clock Time) will appear whilst the unit receives the RDS CT data.

What is a MiniDisc?
The disc is stored in a cartridge. Y ou can handle it easily without worrying about dust,
fingerprints, etc. However, dust entering the opening of the cartridge, dirt on the cartridge, warping, etc. may cause malfunctions. Please note the following.
■
To prevent recorded MiniDiscs from being
erased accidentally
Slide the accidental erase prevention tab, located on the side of the MiniDisc, in the
direction indicated by the arrow.
● The MiniDisc will then be protected against accidental erasure.
Recordable
To add a recording to such a MiniDisc, slide the accidental erase prevention tab back
to its original position.
■
Helpful tip when attaching a label
When attaching a label to a MiniDisc cartridge, be sure to note the following. If the label
is not attached properly, the MiniDisc may jam inside the unit and it may not be possible to remove it.
● If the label peels off or partially lifts away, replace it with a new one.
● Do not put a new label on top of an existing one.
● Attach the label only in the specified location.
■
Types of discs
There are two types of discs: playback-only and recordable types.
● Playback-only MiniDisc:
This type of MiniDisc is used for commercially available
prerecorded music. This is the same kind of optical disc
as CDs. Playback is performed using an optical pickup.
(Recording and editing are not possible.)
● Recordable MiniDisc:
This is a “raw disc” on which recording can be performed.
A magneto optical disc is used. Recordings are made
using a laser and magnetic field. Repeated recording is
possible.
Recording
prevented
A Shutter will be used on
only one side (back).
Shutters will be used on
both sides.
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 recording 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 a MiniDisc 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 MiniDisc 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 performed, 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.
A MiniDisc which has been recorded or edited repeatedly may skip during fast reverse or fast forward.

Measure to be taken when a disc cannot be removed due to a mechanism trouble
First, remove the mechanism unit section from the set, and check for the state of the disc.
(Remove the top plate R if necessary.)
<State of the disc>
(1) When the disc is in the normal PLAY (chucking) position -> Try to eject the disc by turning the mode big gear/tray big gear
manually.
* At this time, be sure to adjust the tray's position (height).
(2) When the disc is in the normal STOCK position -> Try to eject the disc by turning the tray big gear manually.
* At this time, be sure to adjust the tray's position (height).
(3) When the disc is not in the normal position -> The tray or disc is not in the normal position. (The tray or disc may catch
somewhere.)
Remove the TOP PLATE F/DISC OB lever.
Unlock the tray lock lever and pull out the tray which is not caught.
Move the caught tray or disc and remove the disc.
In case of (1) and (2), the mechanism is normal (defective circuit parts, etc.). However, it may stop somewhere.
This is the reason why you should try to turn the tray big gear first.
In case of (3), either of the big gears does not turn.
