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 1
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.

(Except for U.K.)

Using the Radio Data System (RDS)

CD-BA3100H

RDS is a broadcasting service which a growing number of FM stations provide.
These FM stations send additional signals along with their regular programme
signals. They send their station names, and information about the type of pro­gramme such as sports or music, etc.

When tuned to an RDS station, "RDS" and the station name will be displayed.
"TP" (Traffic Programme) will appear on the display when the received broadcast car­ries traffic information, and "TA" (Traffic Announcement) will appear whilst a traffic
information is on air.
"EON" will appear whilst the EON (Enhanced Other Networks information) data is
broadcast.
"PTYI" (Dynamic PTY Indicator) will appear whilst the Dynamic PTY station is
received.
"RT" (Radio Text) will appear whilst the unit receives the Radio text data.
"CT" (Clock Time) will appear whilst the unit receives the RDS CT data.

You can control the RDS by using the buttons on the main unit only.

Information provided by RDS

Each time the DISPLAY MODE button is pressed, the display will switch as fol­lows:

Station name (PS) Frequency

Programme type (PTY) RDS clock time

Date (for 3 seconds)

When you are tuning in to a station other than an RDS station or to an RDS station
which sends weak signal, the display will change in the following order:

(8 Languages)

Programme type (PTY) Clock-time and date (CT)

(English fixed)

Radio text (RT)

Descriptions of the PTY (Programme Type) codes, TP (Traffic Programme) and

If trouble occurs

When this product is subjected to strong external interference

(mechanical shock, excessive static electricity, abnormal sup-

ply voltage due to lightning, etc.) or if it is operated incorrectly, it

may malfunction.

If such a problem occurs, do the following:

1. Set the unit to the stand-by mode and turn the power

on again.

2.

If the unit is not restored in the previous operation, un-

plug and plug in the unit, and then turn the power on.

Note:

If neither operation above restores the unit, clear all the memory

by resetting it.

Clearing all the memory (reset)

1. Press the ON/STAND-BY button to enter the power

stand-by mode.

2.

Whilst pressing down the MEMORY/SET button and the

X-BASS/DEMO button, press the ON/STAND-BY button

until “CLEAR AL” appears.

Caution:

This operation will erase all data stored in memory including

clock, timer settings, tuner preset, and CD programme.

Maintenance

Dirty heads, capstans or pinch rollers can cause poor

sound and tape jams. Clean these parts with a cotton swab

moistened with commercial head/pinch roller cleaner or

isopropyl alcohol.

When cleaning the heads, pinch rollers, etc., unplug the

unit which contains high voltages.

After long use, the deck’s heads and capstans may be-

come magnetised, causing poor sound. Demagenetise

these parts once every 30 hours of playing/recording time

by using a commercial tape head demagnetiser. Read the

demagnetiser’s instructions carefully before use.

Clean the dust or stain on the CD pickup lens using a com-

mercial cleaning disc (brush type).

Notes:

1: Description of the "FM IF Adjustment" is not carried on this

Manual. It is because the IF coil in the FM front end section
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.

2: The parts in the FM front end section are prepared in a

CD SECTION

• Adjustment

Since this CD system incorporates the following automatic
adjustment functions, readjustment is not needed when
replacing the pickup. Therefore, different PWBs and pickups
can be combined freely.
Each time a disc is changed, these adjustments are performed
automatically. Therefore, playback of each disc can be
performed under optimum conditions.

Items adjusted automatically

(1) Offset adjustment (The offset voltage between the head

amplifier output and the VREF reference voltage is
compensated inside the IC.)

* Focus offset adjustment
* Tracking offset adjustment

(2) Tracking balance adjustment (waveform drawing

Fig.16-2 EFBL)

(3) Gain adjustment (The gain is compensated inside the IC

so that the loop gain at the gain crossover frequency will
be 0 dB.)

* Focus gain adjustment
* Tracking gain adjustment

<Assembling method of lift gear>
After setting up the mode big gear in the

(gear on the lower side) at the position (A),
and assemble them, turning it in the arrow direction
into the position (B). (The short tooth directs toward the
center of the mode big gear.)
Check the gap (C) after assembly.
If no gap is found, repeat the above procedure.

Assembling procedure

1. Turn the mode big gear approx. 37 degrees in the arrow direction.

2. Assemble the change box L ass'y.
Note: At this time, the tray joint gear F must be located in the position shown in figure.
Moreover, the gear must be engaged securely.

3. After assembly, return the mode big gear to the initial position.

4. Assemble the lift cam.
Note: At this time, the lift cam (No.40) must be located in the position shown in figure 22.
