CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
HCD-RG550/RG660
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown 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 pick-
up 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.
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.

SETTING AND RELEASING THE CD DISC TRAY LOCK
FUNCTION
This set has a disc tray lock function to prevent discs for
demonstration at shops from theft. While this lock function is set,
the tray will not be delivered out even when the OPEN/CLOSE
button is pressed.
Setting method:
Press the OPEN/CLOSE button while pressing the STOP button.
After a few seconds, the message “LOCKED” will appear on the
fluorescent indicator tube with the tray locked.
Releasing method:
Just as the lock is set, press the OPEN/CLOSE button while
pressing the STOP button.
After a few seconds, the message “UNLOCKED” will appear with
the lock released.
PARTS No.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
Carry out the “S curve check” in “CD section adjustment” and check
that the S curve waveforms is output three times.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to about
350 °C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscou-s (sticky , less prone to flo w) than
ordinary solder so use caution not to let solder bridges occur such
as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may also
be added to ordinary solder.

SECTION 3
TEST MODE
[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 the [POWER] key to turn the power ON.
2. Press three keys of x , [GROOVE] and [POWER] simultaneously.
3. The message “COLD RESET” is displayed on the fluorescent
indicator tube momentarily, then becomes standby states.
[TUNER STEP CHANGE-OVER]
(Except AEP and UK models)
•A step of AM channels can be changed over between 9 kHz and
10 kHz.
Procedure:
1. Press the [POWER] key to turn the power ON.
2. Press the [TUNER BAND] key to select “AM”.
3. Press the [POWER] key to turn the power OFF.
4. Press two keys of [ENTER] and [POWER] simultaneously.
5. The message “9K STEP” or “10K STEP” is displayed on the
fluorescent indicator tube, and thus the channel step is changed
over.
[CD SHIP MODE]
•This mode moves the optical pick-up to the position durable to
vibration. Use this mode when returning the set to the customer
after repair.
Procedure:
1. Press the [POWER] key to turn the power ON.
2. Press the [CD] key to select “CD”.
3. Press two keys of [CD] and [POWER] simultaneously.
4. The message “LOCK” is displayed on the fluorescent indicator
tube, and the CD ship mode is set.
[CHANGE-OVER FUNCTION OF MD/VIDEO]
•This mode is used to enable function of external input to change
over between MD and VIDEO.
Procedure:
1. Set to standby state.
2. Press two keys of [MD VIDEO ] and [POWER] simultaneously.
3. The message “MD” or “VIDEO” is displayed on the fluorescent
indicator tube, and the function of external input is changed
over.

3. Set disc on the tray.
4. While pressing the x key, press the Z key for 5 seconds.
5. The message “LOCKED” is displayed on the fluorescent
indicator tube and the tray is locked. (Even if pressing
the Z key, the message “LOCKED” is displayed on the
fluorescent indicator tube and the tray is locked)
6. To release from this mode, while pressing the x key, press
the Z key for 5 seconds.
7. The message “UNLOCKED” is displayed on the fluorescent
indicator tube and the tray is unlocked.
[AMP TEST MODE]
•This mode is used to set the parameter of AMP IC for adjustment
of tone quality and VACS level and display VACS status.
Procedure:
1. Press the [POWER] key to turn the power ON.

simultaneously.
3. When the AMP test mode is activated, the message “AMP
TEST” is displayed on the fluorescent indicator tube
momentarily.
4. Press two keys of [GAME EQ] and [DISC 2] simultaneously, mode
is changed over to parameter setting of AMP IC and display of
VACS status.
5. When the VACS status, the message VACS level, VACS signal
level, and VACS signal hold le vel is displayed on the fluorescent
indicator tube.
6. Press the [GROOVE] key, DBFB ON/OFF is changed over.
7. Press the [GAME MIXING] key, surround ON/OFF is changed
over.

ELECTRICAL ADJUSTMENTS
CD SECTION
Note:
1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.
2. Use YEDS-18 (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10MW 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. Connect an oscilloscope to TP (FE) and TP (VC).
2. Turn the power on.
3. Load a disc (YEDS-18) and actuate the focus search. (In
consequence of open and close the disc tray, actuate the focus
search)
4. Confirm that the oscilloscope waveform (S-curve) is
symmetrical between A and B. And confirm peak to peak level
within 3 ± 0.5 Vp-p.
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.
RF LEVEL CHECK
Procedure :
1. Connect an oscilloscope to TP (RF) and TP (VC).
2. Turn the power on.
3. Load a disc (YEDS-18) and playback.
4. Confirm that oscilloscope waveform is clear and check if RF
signal level is correct or not.
Note: Clear RF signal wav eform means that the shape “ ◊ ” can be
clearly distinguished at the center of the waveform.
