Page 6: Precaution
SECTION 1 PRECAUTION Safety Precautions Burrs formed during molding may be left over on some parts of the chassis. Therefore, pay attention to such burrs in the case of preforming repair of this system. Please use enough caution not to see the beam directly or touch it in case of an adjustment or operation check.
Page 7 Preventing static electricity Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs. 1.2.1 Grounding to prevent damage by static electricity Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as laser products.
Page 8 Important for laser products 1.CLASS 1 LASER PRODUCT 5.CAUTION : If safety switches malfunction, the laser is able to function. 2.CAUTION : (For U.S.A.) Visible and/or invisible class II laser radiation 6.CAUTION : Use of controls, adjustments or performance of when open.

SECTION 4 ADJUSTMENT Test instruments required for adjustment Standard measuring conditions (1) Digital oscilloscope (100MHz) Power supply voltage : DC14.4V(11 to 16V) Load impedance : 4 Ω (2 Speakers connection) (2) Jitter meter Line Output : 20K Ω (3) Digital tester (4) Electric voltmeter Caution: (5) Tracking offset meter...
Page 25 Adjustment method for jitter After replacing the pickup, set the unit in the service mode to display a jitter value on the LCD. Confirm that the jitter value measured with a jitter meter is within 12% of the jitter value displayed on the LCD. If it is within 12%, then adjustment is not necessary.
Page 26 Jitter value conversion table Load the test DVD and set the unit to the service mode. A jitter value converted to the hex value is displayed on the LCD. Refer to the corresponding decimal notation value shown in the following Jitter Conversion Table. The adjustment is OK if the jitter value measured with a jitter meter is within 12% of the jitter value displayed on the LCD.
