also require this requirement. Any electrical and electronics products launched in the market after June 2006

should meet this RoHS requirements. Products launched in the market before June 2006 are not required to

compliant with RoHS parts. If the original parts are not RoHS complaints, the replacement parts can be non

ROHS complaints, but if the original parts are RoHS compliant, the replacement parts MUST be RoHS

complaints.

If the product service or maintenance require replacing any parts, please confirming the RoHS requirement

before replace them.

2.2. Safety Notice

1. Make sure your working environment is dry and clean, and meets all government safety requirements.

2. Ensure that other persons are safe while you are servicing the product.

DO NOT perform any action that may cause a hazard to the customer or make the product unsafe.

4. Always use approved tools and test equipment for servicing.

5. Never assume the product’s power is disconnected from the mains power supply. Check that it is

disconnected before opening the product’s cabinet.

6. Modules containing electrical components are sensitive to electrostatic discharge (ESD). Follow ESD safety

procedures while handling these parts.

7. Some products contain more than one battery. Do not disassemble any battery, or expose it to high

temperatures such as throwing into fire, or it may explode.

8. Refer to government requirements for battery recycling or disposal.

2.3 .Compliance Statement

Caution: This Optical Storage Product contains a Laser device. Refer to the product specifications and your

local Laser Safety Compliance Requirements.

2.4. General Descriptions

This Service Manual contains general information. There are 3 levels of service:

Level 1: Cosmetic / Appearance / Alignment Service
