SAFETY INFORMATION
This product has been designed and manufactured according to FDA
regulations "title 21, CFR, chapter 1, subchapter J, based on the Radiation
Control for Health and Safety Act of 1968", and is classified as a class 1
laser product. There is no hazardous invisible laser radiation during
operation because invisible laser radiation emitted inside of this product
is completely confined in the protective housings.
The label required in this regulation is shown 1.
OCAUTION
USE OF CONTROLS OR ADJUSTMENT OR PERFORMANCE OF
PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN
HAZARDOUS RADIATION EXPOSURE.
Optical pickup:
Type
: GH20707A2A
Manufacturer
: SHARP CORPORATION
Laser output
: Less than 1mW on the objective lens
Wavelength
: 788±5 nm (CD), 650±10 nm (DVD)
1 For U.S.A.
The CORE PCB is beneath the VIDEO PCB. So remove the VIDEO
PCB before attempting adjustments.
3-1 Sled Offset Adjustment
1. Connect the probe of oscilloscope to pin 1 (SLCNT) of P205 on
CORE PCB, and the probe earth to pin 2 (SL18V).
2. Set the oscilloscope's voltage range to DC100mV, and the time
calibration to 10mS.
3. Adjust potentiometer R232 for a potential difference of 0V
between pins 1 and 2.
3-2 Sled Gain Adjustment
1. Connect the probe of oscilloscope to pin 3 (H1OUT) of P205 on
CORE PCB, and the probe earth to pin 2 (SL18V).
2. Set the oscilloscope's voltage range to AC200mV, and the time
calibration to 10mS.
3. Press the DF range button on RC-668 (P/No. E00380000A), a
remote controller for VRDS-8, to activate the sled, and adjust
potentiometer R235 for a sine wave output of 1Vp-p at pin 3.
Pressing the DF range button again beings the unit back to the
normal mode.
