In case of soldering iron with temperature control, please set it to 700 20F (370 10C). Pb free solder will tend to splash when heated too high (about 1100F/600C). When soldering or unsolder

19、ing, 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-VK62DEE 6 Precaution of Laser Diode Caution : This product utilizes a laser diode with the unit turned ON, invisible laser radiatio

20、n is emitted from the pick up lens. Wavelength : 785 nm(CD)/662 nm(DVD) Maximum output radiation power from pick up : 100 W/VDE Laser 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 d

21、angerous. 2. Do not adjust the variable resistor on the pick up unit. It was already adjusted. 3. Do not look at the focus lens using optical instruments. 4.

25、 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 destruction during repair. 7.1. Handling Optical Pickup 1. Do not impact on optical pickup as the unit st

26、ructurally 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 from electrostatic destruction (Refer to Fig. 7.1 and Fig. 7.2) 3. Do not handle flexible cables forc

27、ibly 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 board, cut the anti-static flexible cable. (Refer to Fig. 7.1) Fig. 7.1 7.2. Replacing Precautions fo

28、r 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 prevention. Please remove the short clip and be sure to check that the short land is open, before connectin

29、g. (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 static electricity accumulated in your body. (Refer to Fig. 7.2) 2. Work place grounding Place a conductive

30、material (conductive sheet) or iron board 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 electricity charged in clothes.

Consumers worldwide are using PCs to create their own collections of music, photos and even video by burning the

32、m onto CDs. But how these 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 dr

33、amatically improves the digital 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

34、 on consumer electronics devices 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, Hi

35、ghMAT enable easier and more 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,

36、 there are numerous, inconsistent ways that devices read the data. For the consumer, the playback experience can be confusing: 15 SA-VK62DEE A Solution Created: HighMAT delivers a better digital media access experience by creating a standard approach for PCs to structure digital media on various phy

37、sical formats and for playback 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 inconsistant playback experince.
