SHOCK, FIRE HAZARD SERVICE TEST :

CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC

cord connector pins ( with unit NOT connected to AC mains and its Power switch ON ), and the face or Front Panel of product and controls and chassis bottom. Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied, and verified before it is return to the user/customer. Ref. UL Standard No. 1492.

In case of difficulties, do not hesitate to contact the Technical Department at above mentioned address.

Electrical adjustment 1 Precaution during confirmation of Laser Diode emission

During adjustment, do not view the emission of a laser diode from lust above for confirmation. This may damage your eyes.

2 Precaution on handling of Optical pick-up (KMS-260B)

The laser diode in an optical pick-up is easy to be subject to electrostatic destruction. Therefore, solder-bridge the laser tap on the flexible board when handling the optical pick-up. When removing the flexible board from the connector, make a solder bridge in advance, then remove the board. Be careful not to remove the solder bridge before inserting the connector. Moreover, take careful measures against electrostatic destruction. The flexible board is cut easily. Handle the flexible board with care.

3 Precaution during adjustment

1) Perform the adjustment and confirmation marked with "O" in the order shown in the table when the parts below are replaced.

2. Laser power adjustment O O X O

3.Trtvense adjustment O O X O

4. Focus bias adjustment O O X O

5. Error rate confirmation O O X O

2) In the test mode, perform the adjustment. After adjustment is completed, chancel the test mode.

3) Perform the adjustment in the order described.

4) Use the following tools and measurement equipment.

CD test disc TGYS-1 Laser power meter Oscilloscope (with bandwidth of more than 40 M Ohms) (Calibrate the probe before measurement) Digital voltmeter Thermometer

5) Take care that VC and GND (ground) are not connected on the oscilloscope when two or more signals are monitored on the oscilloscope. (VC and GND are short-circuited in this case,)

During this adjustment, the oscilloscope changes in units of about 2%. Adjust so that the waveform comes nearest to the specified value. (MO groove read power traverse adjustment)

Notes:

1. Data is erased during MO write when a recorded disc is used for this adjustment

2. If the traverse waveform is difficult to be monitored, connect an oscilloscope as shown in the figure below.
