• Namely, two speakers are connected in parallel to one
amplifier.
• In the Pro Logic BYPASS mode the amplifier for C-ch (center

MUTE state. The SP output is cut.
• In the normal mode of Pro Logic ON mode the amplifiers for
C-ch and S-ch are in operative state, so that the SP output
appears.
• In the Phantom mode of Pro Logic ON mode the amplifier for
C-ch is in MUTE state, so that the SP output is cut. The

L-ch or R-ch outputs.
• If you want to output signal waveform to S-ch SP out, you can
use either Normal mode or Phantom mode. However, 180°
reverse phase input must be given to L-ch/R-ch INPUT.

RDS (Radio Data System) OPERATION
DISPLAY MODE
Receiving FM Stations with RDS (Radio Data
System)
Descriptions of the PTY (Programme Type) codes, TP (Traffic
Programme) and TA (Traffic Announcement)
Eith the CD-C471H, you can search for and receive the
forrowing PTY, TP and TA signals.
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.

When the TP and TA appear at the same time, an announcement is being made.

With the CD-C471H, you can display two types of RDS

ASPM is not only very usefull for PTY search, but also EON operation.

PTY search function is equal to FM band search function as a result.
1. Introduction of RDS for CD-C471H
CD-C471H 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.

2.The difference point from current CD-C75H RDS. (CD-C75H — CD-C471H)
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.
6. Need to change RDS logo due to add EON feature.
7. Added EON—TI, EON—PTY function.
3. Summary of CD-C471H 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-C471H EON is
basically stand-by and receiving method, along with the Guidelines for EON implementation.

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".

NOTES ON SCHEMATIC DIAGRAM
• 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.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type

TROUBLESHOOTING (CD SECTION)
When the CD does not function
When the CD section does not operate When the objective lens of the optical pickup is dirty,this section may not operate.Clean
the objective lens,and check the playback operation.When this section does not operate even after the above step is taken,check
the following items.
Remove the cabinet and follow the troubleshooting instructions.
"Track skipping and/or no TOC(Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup lens.
Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below."
