The release method of a CD disc tray LOCK function
There is a disc lock function for the disc theft prevention for a demonstration at a shop front in this machine. Procedue:
1. Press the ?/1 button to turn the set on.
2. Press two buttons of x and Z (EJECT) simultaneously for five seconds.
3. The message “LOCKED” is displayed and the tray is locked. (Even if exiting from this mode, the tray is still locked.)
4. Press two buttons of x and Z (EJECT) simultaneously for five seconds again.
5. The message “UNLOCKED” is displayed and the tray is unlocked.
6. To exit from this mode, press the ?/1 button to turn the set off.
Unleaded solder
Boards requiring use of unleaded solder are printed with the lead­free 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 viscous (sticky , less prone to flow) 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.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY .

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
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.

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

HCD-RG222
[Change-over of AM Tuner Step between 9 kHz and 10 kHz]
•A step of AM channels can be changed ov er 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 TUNER/BAND 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.
[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 , PLAY MODE/TUNING MODE ,
and DISC 1 simultaneously.
2. The fluorescent indicator tube displays “COLD RESET” and
the set is reset.
[Aging Mode]
This mode can be used for operation check of CD section and tape deck section.
• If an error occurred: The aging operation stops and is displayed status.
• If no error occurs: The aging operation continues repeatedly.
1. Operating method of Aging Mode
Turn on the main power and select “CD” of the function.
1) Set three discs in tray. Select ALL DISCS, and REPEAT OFF.
2) Load the tapes recording use into both decks.
3) Press three buttons x , PLAY MODE/TUNING MODE ,
and EX-CHANGE simultaneously.
4) Aging operations of CD and tape are started at the same time.
5) To exit the aging mode, perform [Cold Reset].
