3 ADJUSTMENTS
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 CORE PCB
calibration to 10mS.
3. Adjust potentiometer R232 for a potential difference of 0V
between pins 1 and 2.

P205 (Bottom Side)
3-2 Sled Gain Adjustment R235
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.

adhesive with UV irradiation.
Avoid applying a strong pushing force to the PU BASE ASSY
when removing/installing the PUSH SW 9.
First tighten

When fastening the SA SLED MOT ASSY a, push it against screws
the locating pin.
HOUSING ASSY,MOTOR
Avoid disassembling parts that are not "exploded" in the
diagram (such as PU BASE ASSY, MOTOR HOUSING ASSY).
Dedicated tools are required to assemble them. When those
parts are needed to replace, the MECH UNIT itself should be
replaced.
Fasten the STOPPER BELT PLATE @ so that there is a
clearance of 1 mm between it and PULLEY (B) PLATE ..
