Panasonic DVDRV60 specifications Precaution Of Laser Diode, Handling Precautions For Traverse Deck

DVD-RV60

Caution

Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

8.Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise hamless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient to damage an ES device).

3 PRECAUTION OF LASER DIODE

Caution

This unit utilizes a class I laser. Invisible laser radiation is emitted from the optical pickup lens when the unit is turned on:

1.Do not look directly into the pickup lens.

2.Do not use optical instruments to look at the pickup lens.

3.Do not adjust the preset variable resistor on the optical pickup.

4.Do not disassemble the optical pickup unit.

5.If the optical pickup is replaced, use the manufactures specified replacement pickup only.

6.Use of control or adjustment or performance of procedures other than those specified herin may result in hazardous radiation exposure.

4 HANDLING PRECAUTIONS FOR TRAVERSE DECK

The laser diode in the optical pickup may break down due to potential difference caused by static electricity of clothes or human body.

So be careful of electrostatic break down during repair of the optical pickup.

4.1.Handling of optical pickup

1.Do not subject the optical pickup to static electricity as it is extremely sensitive to electrical shock.

2.To prevent the breakdown of the laser diode, an antistatic shorting pin is inserted into the flexible board (FPC Board). When removing or connecting the short pin, finish the job in as short times as possible.

3.Be careful not to apply excessive stress to the flexible board (FPC Board).

4.Do not turn the variable resistor (Laser power adjustment).

4.2.Grounding for electrostatic breakdown prevention

1.Human body grounding

Use the antistatic wrist strap to discharge the static electricity from your body.

2.Work table grounding

Put a conductive material (sheet) or steel sheet on the area where the optical pickup is placed and ground the sheet.

Caution

The static electricity of your clothes will not be grounded through the wrist strap. So take care not to let your clothes touch the optical pickup.
