CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
HCD-RV20/RV50/RV60
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.
