Please use a high temperature soldering iron. In case of soldering iron with temperature control, please set

19、 it to 700 20F (370 10C). Pb free solder will tend to splash when heated too high (about 1100F/600C). When soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat the soldering points with the Pb free solder until it melts enough. 6 SA-VK6

20、1DGS 7 Cautions to be taken when handling Optical Pickup The laser diode used inside optical pickup could be destroyed due to static electricity as a potential difference is caused by electrostatic load discharged from clothes or human body. Handling the parts carefully to avoid electrostatic destru

21、ction during repair. 7.1. Handling Optical Pickup 1. Do not impact on optical pickup as the unit structurally uses an extremely precise technology. 2. Short- circuit the flexible cable of optical pickup remove from the circuit board using a short- circuit pin or clip in order to prevent laser diode

22、from electrostatic destruction (Refer to Fig. 7.1 and Fig. 7.2) 3. Do not handle flexible cables forcibly as this may cause snapping. Handle the parts carefully (Refer to Fig. 7.1) 4. A new optical pickup is equipped with an anti- static flexible cable. After replacing and connecting to the flexible

23、 board, cut the anti- static flexible cable. (Refer to Fig. 7.1) Fig. 7.1 7.2. Replacing Precautions for Optical Pickup Unit DVD/CD Optical Pickup The optical pickup by which part supply was carried out attaches the short clip to the flexible board for laser diode electrostatic discharge damage prev

24、ention. Please remove the short clip and be sure to check that the short land is open, before connecting. (Please remove solder, when the short land short- circuits.) 7.3. Grounding for Preventing Electrostatic Destruction 1. Human body grounding Use the anti- static wrist strap to discharge the sta

25、tic electricity accumulated in your body. (Refer to Fig. 7.2) 2. Work place grounding Place a conductive material (conductive sheet) or ironboard where optical pickup is placed. (Refer to Fig. 7.2) Note : Keep your clothes away from optical pickup as wrist strap does not release the static electrici

Fig. 7.2 7 SA-VK61DGS 8 Precaution of Laser Diode Caution : This product utilizes a laser diode with the unit turned ON, invisible laser radiation is emitted from the pick up lens. Wavelength : 780 nm(CD)/658 nm(DVD) Maximum output radiation power from pick up : 100 W/VDE Lase

27、r radiation from pick up unit is safety level, but be sure the followings: 1. Do not disassemble the optical pick up unit, since radiation from exposed laser diode is dangerous. 2. Do not adjust the variable resistor on the pick up unit. It was already adjusted. 3. Do not look at the focus lens usin

28、g optical instruments. 4. Recommend not to look at pick up lens for a long time. CAUTION! THIS PRODUCT UTILIZES A LASER.

What is HighMAT? This word combines the abbreviations of Matsushita El

30、ectric Industrial Co. Ltd. and High Performance Media Access Technology, and is a trademark of Microsoft Corporation. The products with the HighMAT logo shown below are made according to the HighMAT standard. HighMAT is a format that allows users to save digital contents such as photographs, audio,

31、and images on a CD. This gives consistency in the way of reading data when general consumer products (such as DVD players) and PCs are used, and thus, it is easy to operate for the user. 12.2. Why use HighMAT? Up to now, there was no harmonized standard from playing digital content stored in CD- ROM

32、 formats (including CD- R) on consumer products like DVD players.Therefore, we used to have problems such as follow: There was no common play list or attached information on contents, which is called metadata. The data compression method differed according to the equipment. As the number of CD- ROMs

33、 recorded increased retrieved the contents became more difficult. Because display and operation methods were different depending on the equipment, the play order of the content on the same disc could change. 12.3. The advantages of using HighMAT Applying the HighMAT standard will solve the following

34、 problems and will improve usability. It will create a common user interface for both PC and consumer products. Regardless of the types of consumer products, such as DVD players, portable CD players, car stereos, and micro computers, a consistent way to pay for digital content will be created and it

35、 will make it easier to retrieve data. 14 SA-VK61DGS You can also play digital content on the disc, which was created in accordance with the HighMAT format with a conventional CD- ROM player. 12.4.
