SAFETY-RELATED COMPONENT
WARNING!!

COMPONENTS IDENTIFIED BY MARK ON THE
SCHEMATIC DIAGRAM AND IN THE PARTS LIST ARE
CRITICAL FOR RISK OF FIRE AND ELECTRIC SHOCK.
REPLACE THESE COMPONENTS WITH ONKYO
PARTS WHOSE PART NUMBERS APPEAR AS SHOWN
IN THIS MANUAL.
MAKE LEAKAGE-CURRENT OR RESISTANCE
MEASUREMENTS TO DETERMINE THAT EXPOSED
PARTS ARE ACCEPTABLY INSULATED FROM THE
SUPPLY CIRCUIT BEFORE RETURNING THE
APPLIANCE TO THE CUSTOMER.

SERVICE PROCEDURES 1

PROTECTION OF EYES FROM LASER BEAM DURING SERVICING

C-701A

This set employs a laser. Therefore, be sure to follow
carefully the instructions below when servicing.

WARNING!!

SERVICE WARNING : DO NOT APPROACH THE
LASER EXIT WITH THE EYE TOO CLOSELY.
IN CASE IT IS NECESSARY TO CONFIRM LASER
BEAM EMISSION, BE SURE TO OBSERVE FROM
A DISTANCE OF MORE THAN 30cm FROM THE
SURFACE OF THE OBJECTIVE LENS ON THE
OPTICAL PICKUP BLOCK.

LASER WARNING LABEL

The labels shown below are affixed.

1. Warning label

Laser Diode Properties

Material: GaAS/GaAlAs
Wavelength: 780nm
Laser output: max. 0.5mW*
Emission Duration: continuous
*This output is the value measured at a distance about 1.8mm
from the objective lens surface on the Optical Pickup Block.

DANGER:

INVISIBLE LASER RADIATION WHEN OPEN AND
INTERLOCK FAILED OR DEFEATED. AVOID DIRECT
EXPOSURE TO BEAM.

CAUTION:

HAZARDOUS LASER AND ELECTROMAGNETIC
RADIATION WHEN OPEN AND INTERLOCK DEFEATED.

ATTENTION:

RAYONNEMENT LASER ET ELECTROMAGNETIQUE
DANGEREUX SI OUVERT AVEC L'ECLENCHEMENT
DE SECURITE ANNULE.

2.Safety check out

(Only U.S.A. model)

After correcting the original service problem perform
the following safety check before releasing the set
to the customer.
Connect the insulating-resistance tester between the
plug of power supply cord and terminal GND on the
back panel.
Specifications: More than 10 M ohm at 500V.

SERVICE PROCEDURES 2

1. Removement of tray

1. Remove the top cover

2. Turn the locked screw to the clockwise to release the lock of gear.

2. Replacement of optical pick-up

The laser diode in the optical pickup block is so sensitive to static
electricity, surge current and etc. that the components are liable to
be broken down or its reliability remarkably deteriorated.
During repair, carefully take the following precautions.

1. Solder the LD short terminal on mechanism.

2. Disconnect the flexible flat cable P101.

3. Replace the optical pickup.

4. Connect the flexible flat cable P101.

5. Unsolder the LD short terminal on mechanism.

NOTE

1. Ground for the work-desk.
Place a conductive sheet such as a sheet of copper
(with impedance lower than 10Mohm) on the work­ desk and place the set on the conductive sheet so that
the chassis can be grounded.

2. Grounding for the test equipments and tools.
Test equipments and toolings should be grounded in
order that their ground level is the same the ground of
the power source.

Pick up short land

3. Grounding for the human body.
Be sure to put on a wrist-strap for grounding whose
other end is grounded.
Be particularly careful when the workers wear
synthetic fiber clothes, or air is dry.

4. Select a soldering iron that permits no leakage and
have the tip of the iron well-grounded.

5. Do not check the laser diode terminals with the
probe of a circuit tester or oscilloscope.

ADJUSTMENT PROCEDURE

1. SERVO ADJUSTMENT

1-1. Preparation
Set the VR123 is center position.
Connect the cables to the test point. (Fig.-1)

1-2. Focus gain adjustment
Load the test disc (YEDS-18) on the tray and play the track 2.
Adjust R123 until 1kHz the waveform of channels 1 and 2 on
oscilloscope become specified level.
Check the jitter meter reading . It must be less than 12ns.
1-3. Remove the oscilloscope and audio oscillator.
