19、hen servicing and handling the laser diode. 7.1. Cautions to be taken in handling the Optical Pickup Unit The laser diode in the optical pickup unit may be damaged due to electrostatic discharge generating from clothes or human body. Special care must be taken avoid to electrostatic discharge damage

20、 when servicing the laser diode. 1. Do not give a considerable shock to the optical pickup unit as it has an extremely high-precise structure. 2. To prevent the laser diode from the electrostatic discharge damage, the flexible cable of the optical pickup unit removed should be short-circuited with a

21、 short pin or a clip. 3. The flexible cable may be cut off if an excessive force is applied to it. Use with caution when handling the flexible cable. 4. The antistatic FPC is connected to the new optical pickup unit. After replacing the optical pickup unit and connecting the flexible cable, cut off

22、the antistatic FPC. 7.2. Cautions to be taken when replacing the Optical Pickup Unit The flexible cable of the optical pickup unit which was supplied as a component is equipped with a short clip to prevent the laser diode from being damaged due to electrostatic discharge. Remove the short clip befor

23、e connecting the flexible cable and make sure that the short land is open. (If the flexible cable is short-circuited, remove the solder.) 7.3. Grounding for electrostatic breakdown prevention Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be dama

24、ged by static electricity in the working environment. Proceed servicing works under the working environment where grounding works is completed. 7.3.1. Worktable grounding 1. Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet. 8 SA-HT3

Consumers worldwide are using PCs to create their own collections of music, photos and even video by burning them onto CDs. But how these

27、collections can be experienced across different devices can be confusing to navigate, time consuming to access for a DVD player, and be incomplete in terms of music information available to the customer. HighMAT offers a solution to this growing consumer problem. HighMAT dramatically improves the di

28、gital media experience on consumer electronic devices by delivering a simple, standardized approach that allows consumers who have created personal collections of digital music, photography and video on their PC to: Create a HighMAT CD or DVD which can be easily played back on consumer electronics d

29、evices such as CD and DVD players, and car stereos. Move digital media files (using recordable media such as CD-R and CD-RW) between the PC and various playback devices such as CD and DVD players. A new standard for creating personal media on consumer electronic devices, HighMAT enable easier and mo

30、re seamless interoperability between Windows PCs and devices designed for your living room, or the car. 11.2. Why take advantage of HighMAT? A Problem Defined:Today, when consumers create their own digital audio, video or photo collections on CD-R or other physical formats, there are numerous, incon

31、sistent ways that devices read the data. For the consumer, the playback experience can be confusing: 14 SA-HT335EE A Solution Created: HighMAT delivers a better digital media access experience by creating a standard approach for PCs to structure digital media on various physical formats and for play

32、back devices to read the data. 11.3. Benefits of HighMAT? ConventionalHighMAT Even though DVD player is CD-R/RW compatible, the inconsistent ways that various DVD players can read the music or photos files often leads to a confusing and inconsistent playback experince.
