HCD-RV20/RV50/RV60
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCKOR BASE UNIT
The laser diode in the optical pick-up block may suffer
electrostaticbreakdown because of the potential difference
generated by thecharged electrostatic load, etc. on clothing and
the human body.During repair, pay attention to electrostatic
break-down and alsouse the procedure in the printed matter which is
included in therepair parts.The flexible board is easily damaged
and should be handled withcare.
NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model
is concentrated so as to be focused onthe 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 capableof emitting radiation
exceeding the limit forClass 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 LOCKFUNCTIONThis set has
a disc tray lock function to prevent discs fordemonstration at
shops from theft. While this lock function is set,the tray will not
be delivered out even when the OPEN/CLOSEbutton is pressed.
Setting method:Press the OPEN/CLOSE button while pressing the
STOP button.After a few seconds, the message “LOCKED” will appear
on thefluorescent indicator tube with the tray locked.
Releasing method:Just as the lock is set, press the OPEN/CLOSE
button whilepressing the STOP button.After a few seconds, the
message “UNLOCKED” will appear withthe lock released.

THIS NOTE IS COMMON FOR PRINTED WIRINGBOARDS AND SCHEMATIC
DIAGRAMS.(In addition to this, the necessary note isprinted in each
block.)
for schematic diagram:• All capacitors are in µF unless
otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolyticsand
tantalums.
• All resistors are in Ω and 1/4 W or less unless otherwise
specified.• % : indicates tolerance.• f : internal component.• C
: panel designation.
• A : B+ Line.• B : B– Line.• H : adjustment for repair.•
Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.• Voltages are taken with a
VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-tion
tolerances.no mark : FM( ) : CD[ ] : TAPE
• Waveforms are taken with a oscilloscope.Voltage variations may
be noted due to normal produc-tion tolerances.
• Circled numbers refer to waveforms.• Signal path.
F : FMf : AME : PB (DECK A)d : PB (DECK B)G : REC (DECK B)J :
CDc : digital outL : VIDEO
for printed wiring boards:• X : parts extracted from the
component side.• Y : parts extracted from the conductor side.• x :
parts mounted on the conductor side.• : Pattern from the side which
enables seeing.
(The other layer’s patterns are not indicated.)
Note: The components identified by mark 0 or dotted linewith
mark 0 are critical for safety.Replace only with part number
specified.
