Since this CD system incorporates the following automatic adjustment function, when the pickup is replaced, it is not necessary
to readjust it.
Since this CD unit does not need adjustment, the combination of PWB and laser pickup unit is not restricted.
• Automatic adjustment item
1. Focus offset (Fig. 11-2)
2. Tracking offset (Fig. 11-3)
3. E/F balance (tracking error balance) (Fig. 11-4)
4. RF level AGC function (HF level: constant)
5. RF level automatic follow-up of the tracking gain
This automatic adjustment is performed each time a disc is changed. Therefore,
each disc is played back using the optimal settings.

RDS (Radio Data System) OPERATION
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 stations 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 announce-
ment is being made.
When only the TA appears, an announcement is not being
made. (See page 15.)
Information Provided by RDS
With the CD-C421/C411H, you can display two types of RDS
service. To show them in the display, press the DISPLAY
MODE button.
Each time you press the DISPLAY MODE button, the display
will change to show the following information.
PS (Programme Service): Station names commonly
known will be diaplayed.
"NO PS" appears if no signal
is being sent.
PTY (Progamme Type): Programme type will be
diplayed.
"NO PTY" appears if no
signal is being sent.
Station Frequency: Station frequencies.
Descriptions of the PTY (Programme Type) codes, TP (Traffic
Programme) and TA (Traffic Announcement)
Eith the CD-C421H/C411H, you can search for and receive
the forrowing PTY, TP and TA signals.

4. No adjust type (None adjusting circuit.)
5. Added EON button.
6. Need to change RDS logo due to add EON feature.
7. Added EON—TI, EON—PTY function.
3. Summary of CD-C421H/C411H RDS—EON operation
EON—PTY: Select and set the desired “PTY” → stand-by → switch 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 toON 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 sta
tion. 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 CD-C421/C411H EON is basi
cally stand-by and receiving method, along with the Guidelines for EON implementation.
• 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.
Same PI code — freq: different
(AF’S)
PS: same
PTY: same
Each PI has AF’S list by individually.
Exa: P1 has f
1, f2, f3 (same PTY).
P2 has f
4, f5 (same PTY).
[For example] Pickup and memorized to preset CH.
f 1
f 2 f 3
P 1 (PI cord)
PS 1 (Station Name)
f 5 f 4
P 2
PS 2
f 6
f 7 f 8
P 3
PS 3
f 9 f 10
f 11 f 12 f13
P 4
PS 4
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 CD-C421H/C411H
CD-C421H/C411H 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 — CD-C421H/C411H)
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.

EON summary notice for reference
1. EON-TI/PTY EON stand-by can be set, only when EON ind. lights up.
While EON ind. goes out (NO EON STATION), EON stand-by can't be set.
If the EON button is pressed, then “NO EON” is indication the display.
2. EON-TI/PTY Even if switch back ON→TN station continue to keep EON stand-by.
3. EON-TI Don’t switch TN→ON during TN broadcast TA. (same item)
4. EON-TI/PTY
EON can be cancelled during receiving ON station by pressing EON button if necessary and
switch back ON
→
TN.
5. EON-TI/PTY EON stand-by is perfectly cancelled (cleared) by pressing EON button 2 times during stand-by or
powerOFF or Tun Up/ Down or change band or recall pre-set CH.
6. EON-TI/PTY After setting EON stand-by, stand-by items can be confirmed by pressing EON button one time.
7. EON-TI/PTY EON button function: •EON setting
•Confirm stand-by items
•Cancel (ON→TN)
•EON clear cancel (2 times)
8. EON-TI/PTY After setting EON-TI and EON-PTY stand-by, if when EON data is not transmitted, EON ind goes out
and EON stand-by is automatically cancelled display “NO EON”.
9. EON-TI EON-TI stand-by can't be set. When TP=0,TA=0(TN) even if EON ind. lights up and the EON button is
pressed then “NO TI” is indication the display.
10. EON-PTY Don’t switch TN→ON during TN broadcast same specified PTY. (same item of PTY)
11. EON-TI/PTY Switch TN→ON→ TN station one cycle.
Never switch TN→ON1→ON2→ Other net to other net station.
12. EON-TI/PTY After switch TN→ON station. When ON station is NO RDS, NO signal, TA=OFF or different PTY items.
The receiver switch back ON→TN displaying “NO READY”.
13. During receive ON station. when ON station become to be NO RDS, NO signal, TA=ON to OFF or
different PTY item, The receiver switch back ON→TN.
14. EON-TI/PTY Switch TN→ON in case of 2 more stations exist, comparing field strength and switch to the strongest
station, if these signals are same strength, switch to the first previous station.
If same frequency as AF'Sexists in the preset memory, then switch TN→ON (preset memory station)
straight.
In case of exist 2 more preset memories of AF’S,then switch to the preset CH which taken in EON DATA
first, also in this case no concern to field strength.
15. Even if switch TN→ON preset memory straight, that ON station is very weak signal, then search another
AF'S (ON) station comparing field strength and switch to the strongest station as a result. Of all atations
of AF'S are very weak or no good condition, then, switch back ON→TN automatically display "NO
READY".
16. EON-TI/PTY No linkage volume, power ON/OFF, and switch function.

• Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression “capacitance/withstand
voltage” is used.
