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
(P.P.): Polypropylene type

• Schematic diagram and Wiring Side of P.W.Board for this
model are subject to change for improvement without prior
notice.

has been best adjusted in the factory so that its further
adjustment is not needed at the field. When replacing the
FM front end assembly, no adjustment is needed either.

CD SECTION

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.

• 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.

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

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-C621H

CD-C621H 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-C621H)

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-C621H 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 AF M FAIRS) 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 CD-C621H EON is basically stand-by and receiving method, along with the Guidelines for EON implementation.

CD-C621H

RDS (Radio Data System) OPERATION

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 announcements, and the

TA (Traffic Announcement) will appear whilst a traffic announcement is being received.

EON will appear whilst the EON (Enhanced Other Networks information) data is being broadcast.

The PTYI (Dynamic PTY Indicator) will appear whilst the Dynamic PTY station is being received.

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.

Information Provided by RDS

With the CD-C621H, you can display three 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 displayed.

"NO PS" appears if no signal

is being received.

PTY (Programme Type): Programme type will be dis-

played.

"NO PTY" appears if no sig-

nal is being received.

RT (Radio Text): Radio text will be displayed.

"NO RT" appears if no signal

is being received.

Station Frequency: Station frequencies.

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."

Turn the power off.
Gently clean the lens with a lens cleaning tissue and a small amount of isopropyl alcohol.
Do not touch the lens with the bare hand.

Dust gradually accumulates on the objective lens during use, and it may degrade performance.
To avoid this problem, use a cleaning disc designed for CD optical pickup lenses.

HOW TO USE

1. Using the brush in the cleaner cap, apply 1 or 2 drops of the cleaning fluid to the brush on the CD cleaner disc which has
the mark next to it.

2. Place the CD cleaner disc onto the CD disc tray with the brush side down, then press the play button.

3. You will hear musicfor about 20 seconds and the CD player will automatically stop. If it continues to turn, press the stop button.

CAUTION

The CD lens cleaner should be effective for 30 - 50 operations, however if the brushes become worn out earlier then please
replace the cleaner disc.
If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft cloth.
Do not drink the cleaner fluid or allow it to come in contact with the eyes. in the event of this happening then drink and / or
rinse with clean water and seek medical advice.
The CD cleaner disc must not be used on car CD player or on computer CD ROM drives.
