SAFETY PRECAUTION FOR SERVICE MANUAL

Precaution to be taken when replacing and servicing the
Laser Pickup.

The AEL (Accessible Emission Level) of Laser Power Output
for this model is specified to be lower than Class I Requirements.
However, the following precautions must be observed during
servicing to protect your eyes against exposure to the Laser
beam.

(1) When the cabinet has been removed, the power is turned

on without a compact disc, and the Pickup is on a position
outer than the lead-in position, the Laser will light for several
seconds to detect a disc. Do not look into the Pickup Lens.

(2) The Laser Power Output of the Pickup inside the unit and

replacement service parts have already been adjusted prior
to shipping.

(3) No adjustment to the Laser Power should be attempted

when replacing or servicing the Pickup.

(4) Under no circumstances look directly into the Pickup Lens

at any time.

(5) CAUTION - Use of controls or adjustments, or performance

of procedures other than those specified herein may result
in hazardous radiation exposure.

has been best adjusted in the factory so that its further

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.

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-C611H, 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.

1. Introduction of RDS for CD-C607H/611H

CD-C607H/611H 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-C607H/611H)

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-C3H 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 midwa y.
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 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-C607H/611H EON is basi-

cally stand-by and receiving method, along with the Guidelines for EON implementation.

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.

• The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the chas­sis with no signal given.
