Power consumption
European models:
The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.
230 V AC, 50/60 Hz

Design and specifications are subject to change without notice.
This appliance is classified as a CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT MARKING is located on the rear
exterior.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of soldering iron around 270˚C
during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.

TEST MODE
[MC Cold Reset]
• The cold reset clears all data including preset data stored in the
RAM to initial conditions. Execute this mode when returning
the set to the customer.
Procedure:
1. Press three buttons x , ENTER , and ?/1 simultaneously.
2. The fluorescent indicator tube displays “COLD RESET” and
the set is reset.
[CD Ship Mode]
• This mode moves the pickup to the position durable to vibration. Use this mode when returning the set to the customer after
repair.
Procedure:
1. Press 1/u button to turn the set ON.
2. Press CD button and 1/u button simultaneously until
“STANDBY” appears.
3. When you releaset he buttons, a message “LOCK” is displayed
on the fluorescent indicator tube, and the CD ship mode is set.
[MC Hot Reset]
• This mode resets the set with the preset data kept stored in the
memory. The hot reset mode functions same as if the power
cord is plugged in and out.
Procedure:
1. Press three buttons x , ENTER , and DISPLAY simultaneously.
2. The fluorescent indicator tube becomes blank instantaneously,
and the set is reset.
[CD Service Mode]
• This mode can run the CD sled motor freely. Use this mode, for
instance, when cleaning the pickup.
Procedure:
1. Press ?/1 button to turn the set ON.
2. Select the function “CD”.
3. Press three buttons x , ENTER , and OPEN/CLOSE simultaneously.
4. The CD service mode is selected.
5. With the CD in stop status, continue to press > to move the
pickup to outside track, continue to press . to inside track.
6. To exit from this mode, perform as follows:
1) Move the pickup to the most inside track.
2) Press three buttons in the same manner as step 2.
Note: • Always move the pickup to most inside track when exiting from
this mode. Otherwise, a disc will not be unloaded.
• Do not run the sled motor excessively, otherwise the gear can be
chipped.
[Change-over of AM Tuner Step between 9 kHz and
10 kHz]
• A step of AM channels can be changed over between 9 kHz and
10 kHz.
Procedure:
1. Press ?/1 button to turn the set ON.
2. Select the function “TUNER”, and press TUNER/BAND
button to select the BAND “AM”.
3. Press ?/1 button to turn the set OFF.
4. Press ENTER and ?/1 buttons simultaneously, and the display
of fluorescent indicator tube changes to “AM 9 k STEP” or
“AM 10 k STEP”, and thus the channel step is changed over.
[GC Test Mode]
• This mode is used to check the software version, FL tube, LED,
keyboard, headphone and volume.
Procedure:
1. Press three buttons x , ENTER and DISC 2 simultaneously.
2. LEDs and fluorescent indicator tube are all turned on.
3. When ENTER and DISC2 are pressed at the same time, the
key number check mode starts up. In this mode, the key numbers
of each key series are displayed.
4. In the key check mode, the fluorescent indicator tube displays
“KEY 000”. Each time a button is pressed.
5. When ENTER and DISC2 are pressed at the same time, the
key count check mode starts up. In this mode, the message “KEY
CNT @@” is displayed on the FL display tube. When each
button is pressed, the key row number is incremented first. Then
the key value is then incremented. However, one the button is
pressed, the key value cannot be counted.
6. When ENTER and DISC2 are pressed at the same time, the
headphones check mode starts up. In this mode, the message
“H_P ON” is displayed when the headphones are inserted. When
the headphones are not inserted. the message “H_P OFF” is
displayed.
7. When ENTER and DISC2 are pressed at the same time, the
volume check mode starts up. In this mode, the message
“VOLUME FLAT” is displayed on the FL display tube. When
the volume control knob is rotated in the positive (+) direction,
the message “VOLUME UP” is displayed. When the volume
control knob is rotated in the negative (-) direction, the message
“VOLUME DOWN” is displayed.
8. In order to quit the mode, either press ENTER and DISC2 at
the same time or press the three buttons at the same time as in
step 1.
9. To exit from this mode, press three buttons in the same manner
as step 1, or disconnect the power cord.
13
HCD-DX20/RG30

to its minimum and a message “GEQ MIN” appears.
6. When b (CURSOR LEFT) or B (CURSOR RIGHT) button
is pressed, GEQ is set to flat and a message “GEQ FLAT”
appears.
7. In the test mode, the default-preset channel is called even when
the TUNER is selected and an attempt is made to call the preset
channel that has been stored in memory, by operating the Shuttle
knob. (It means that the memory is cleared.)
8. When a tape is inserted in the Deck B and the TAPE B function
is selected, and when the REC PAUSE/START button is
pressed twice, recording starts.
The VIDEO function is selected automatically as the input
source.

2) Operation during aging mode
In the aging mode, the program is executed in the following
sequence.
(1) Rewind is executed up to the top of tape A and B.
(2) A tape on FWD side is played for 2 minutes.
(3) FF is executed up to either made for 20 second or the end of
tape.
(4) B tape is reversed, and the tape on REV side is played for 2
minutes.
(5) Rewind is executed up to the top of tape.
(6) Returns to step 2, and repeat steps from 2 to 5.
[Function Change Mode]
* elect either VIDEO or MD of the external FUNCTION input.
Procedure:
1. Turn on the power.
2. Press the two buttons MD (VIDEO) and ?/1 at the same
time.
The main power is turned on and the other function of the
previous function is selected and displayed. “MD” or
“VIDEO”.

1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10MΩ impedance.
4. Clean the object lens by an applicator with neutral detergent
when the signal level is low than specified value with the
following checks.
S-Curve Check
Procedure:
1. Supply a 98 MHz signal at 28 dB from the ANTENNA terminal.
2. Tune the set to 98 MHz.
3. Adjust RV101 to the point (moment) when the TUNED
indicator will change from going off to going on.

2. Connect between TP (FEI) and TP (VC) by lead wire.
3. Connect between TP (AGCCON) and TP (D GND) by lead wire.
4. Turn Power switch on.
5. Load a disc (YEDS-18) and actuate the focus search. (In
consequence of open and close the disc tray, actuate the focus
search)
6. Confirm that the oscilloscope waveform (S-curve) is
symmetrical between A and B. And confirm peak to peak level
within 4 ±1 Vp-p.

Procedure:
1. Supply a 98 MHz signal at 60 dB from the ANTENNA terminal.
2. Tune the set to 98 MHz.
3. Measure voltage between pin 21 and pin 23 of IC 101. Adjust
T101 ubtil the voltage becomes 0 V.

Note : • Try to measure several times to make sure than the ratio
of A : B or B : A is more than 10 : 7.
• Take sweep time as long as possible and light up the
brightness to obtain best waveform.

Part No.
• Due to standardization, replacements in the parts
list may be different from the parts specified in the
diagrams or the components used on the set.
• -XX, -X mean standardized parts, so they may
have some difference from the original one.
• Items marked “*” are not stocked since they are
seldom required for routine service. Some delay
should be anticipated when ordering these items.
• RESISTORS
All resistors are in ohms
METAL: Metal-film resistor
METAL OXIDE: Metal Oxide-film resistor
F : nonflammable
