Precaution to be taken when replacing and servicing the laser pickup. The following precautions must be observed during servicing to protect your eyesvagainst exposure to the laser. Warning of possible eye damage when repairing: If the AC power plug is connected when the inner cover of the unit is removed, the laser will light up during focus access (about 1 second) (Fig. 3-1). During this operation, the laser will leak from the opening between the magnetic head and cartridge holder (Fig. 3-2). In order to protect your eyes, you must not look at the laser during repair. Before repairing, be sure to disconnect the AC power plug.

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.

RDS (Radio Data System) OPERATION
DISPLAY
MD-X60H
Receiving FM Stations with RDS (Radio Data System)
RDS is a broadcasting service which a growing number of FM stations are now providing. It allows these FM stqtions to send additional signals along with their regular programme signals. For example, the stations send their station names, and information about what type of programme they broadcast, such as sports or music, etc. When tuned to an FM station which provide the RDS service, the RDS will appear, the station frequency (and then the station name if sent) is displayed. The TP (Traffic Programme) will appear on the display when the received broadcast carries traffic annoucements, and the TA (Traffic Annoucement) will appear whilst a traffic announcement is being received. EON will appear whilst the EON (Enhanced Other Networks information) data is being broadcast.
Note:
When the TP and TA appear at the same time, an announce­ment is being made. When only the TA appears, an announcement is not being made. (See page 34.)
Information Provided by RDS
With the MD-X60H, you can display two types of RDS service. To show them in the display, press the DISPLAY button. Each time you press the DISPLAY button, the display will change to show the following information.
Descriptions of the PTY (Programme Type) codes, TP (Traffic Programme) and TA (Traffic Announcement) Eith the MD-X60H, you can search for and receive the forrowing PTY, TP and TA signals.
News: News Affairs: Topical programme expanding on the
current news or affairs
Info: Programmes on medical service, weather
forecast, etc.
Sport: Sport events Educate: Educational programmes Drama: Radio plays Culture: Programmes on national or regional culture. Science: Programmes on national sciences and
technology.
Varied: Other programmes like comedies or
ceremonies
Pop M: Pop music Rock M: Rock music M.o.R. M: Middle-of-the-road music (usually called
"easy listening")
Light M: Light music Classics: Classics Other M: Other music Alarm: Emergency broadcasts NONE: No Programme type (receive only) TP: Broadcasts which carry traffic
announcements
TA: Traffic announcements are being broadcast
at present.
PS (Programme Service): Station names commonly
known will be diaplayed. " PS: " appears if no signal is being sent.
PTY (Progamme Type): Programme type will be
diplayed. "PTY: " appears if no signal is being sent.
Station Frequency: Channel number and tuning
frequency.
Note:
When the unit is in the EON stand-by mode and a pro­gramme is selected, the unit will display "TI" instead of "TP" or "TA".

• ASPM SCAN: 87.50MHz 108.00 MHz.
• Only RDS signal is memorized by ASPM because RDS signal has PI code and is suitable and convenient for ASPM operation. ASPM Comparing field strength, only one strongest RDS station is memorized of all stations (repeater relay stations) that have same
PI code.
Each PI has AF’S list by individually.
Same PI code — freq: different

P 2 PS 2
f 6 f 7 f 8
P 3 PS 3
Select signals (f1, f5, f7, f10) are memorized in the preset memory by ASPM.
• If tentative - ASPM operation is repeated intententionally, never memorized (over write) at the same frequecy. 1st time ASPM strongest stations of each PI are memorized.
ASPM is not only very usefull for PTY search, but also EON operation. 2nd time ASPM → 2nd strong stations of each PI are memorized and so on. PTY search function is equal to FM band search function as a result.

1. Introduction of RDS for MD-X60H
MD-X60H RDS function is equal to adding EON feature to the current CD-C75H RDS. EON feature is EON—PTY and EON—TI. Although PTY and TI indicators are separated, PTY contains TI in the PTY items (software) like current PTY search items.
NEWS, AFFAIRS, INFO, ALARM, TI (TTL 17 kinds)
EON—PTY EON—TI Can select and stand-by Can select and stand-by
EON—PTY and EON—TI are basically stand-by receive the desired program of ON station.
2.The difference point from current CD-C75H RDS. (CD-C75H — MD-X60H)
1. PTY item: added TA.TTL 18 kind.
2. Each “TP”, “TA” ind. light up or go out individually. “TA” ind. doesn’t light up on current model, CD-C75H due to none EON—TI.
3. Added 3 indicators(in FL) due to adding EON feature. EON: Lights up only during receiving EON data (14A). TI: During EON-TI stand-by Light up
During receiving ON station. blink.
PTY: During EON-PTY stanb-by Light up
During receiving ON station. blink.
4. No adjust type (None adjusting circuit.)
5. Added EON button. (Remote Control Only.)
6. Need to change RDS logo due to add EON feature.
7. Added EON—TI, EON—PTY function.
3. Summary of MD-X60H RDS—EON operation
EON—PTY: Select and set the desired “PTY” stand-byswitch to ON(other network) Station at the start of desired
PTY automatically stay and listen to PTY of ON station switch back to TN(This net) station automatically at the end of PTY(ON) i.e. after changing to another PTY(except AFFAIRS) or cancelling to receive PTY of ON station midway.
EON—TI: Select and set the “TI” stand-by switch to ON station at the start of traffic announcement automati
cally stay and listen to TA of ON station switch back to TN station autmatically at the end of TA(ON). ie after TA(ON) is over or cancelled to receive TA of ON station midway.
When switching TN ON station. In case of exist 2 more stations having the desired(specified) “PTY” or “TI”, the receiver will select and switch to ON station comparing field strength at the same time. But when the frequency of ON station exists in the preset-memory, then reciver switches straight to that ON station(CH), without comparing field strength so can make a quick switching from TN—ON station.Preset memory takes priority of switching TN—ON station. therefore ASPM is usefull not only for PTY search but also for rapid EON switching. Anyway MD-X60H EON is basically stand-by and receiving method, along with the Guidelines for EON implementation.
