About This Manual This manual contains information about maintenance and service of acer products. Use this manual to perform diagnostics tests, troubleshoot problems, and align the acer product. 1.1 Trademark The following terms are trademarks of Acer Inc. : Acer Importance Only trained service personnel who are familiar with this Acer Product shall perform service or maintenance to it. Before performing any maintenance or service, the engineer MUST read the “Safety Note”. -3- Follow ESD safety procedures while handling these parts. and meets all government safety requirements. DO NOT perform any action that may cause a hazard to the customer or make the product unsafe. 6.4 General Descriptions This Service Manual contains general information. 3.3 Compliance Statement Caution: This Optical Storage Product contains a Laser device. or it may explode. Refer to the product specifications and your local Laser Safety Compliance Requirements. Use proper safety devices to ensure your personal safety. Products launched in the market before June 2006 are not required to compliant with RoHS parts. It should be stored for easy access place for quick reference. please read through carefully. If the product service or maintenance require replacing any parts. Modules containing electrical components are sensitive to electrostatic discharge (ESD). 2. There are 3 levels of service: Level 1: Cosmetic / Appearance / Alignment Service Level 2: Circuit Board or Standard Parts Replacement Level 3: Component Repair to Circuit Boards -4- . 2.2. If the original parts are not RoHS complaints. 2. the replacement parts MUST be RoHS complaints. Ensure that other persons are safe while you are servicing the product. 2. Introduction This section contains general service information. Always use approved tools and test equipment for servicing. Make sure your working environment is dry and clean. please confirming the RoHS requirement before replace them. 4. or expose it to high temperatures such as throwing into fire.2 Safety Notice 1. Check that it is disconnected before opening the product’s cabinet.1 RoHS (2002/95/EC) Requirements The RoHS (Restriction of Hazardous Substance in Electrical and Electronic Equipment Directive) is a legal requirement by EU (European Union) for the global electronics industry which sold in EU and some counties also require this requirement. 7. Never assume the product’s power is disconnected from the mains power supply. but if the original parts are RoHS compliant. Some products contain more than one battery. – Applied to all countries require RoHS. Refer to government requirements for battery recycling or disposal. 5. Do not disassemble any battery. 8. 2. Any electrical and electronics products launched in the market after June 2006 should meet this RoHS requirements. the replacement parts can be non ROHS complaints. 7 Millions 1000:1 (typ.). *All spec.
