11、caution of Laser Diode CAUTION: 1. Do not look directly into the pick up lens. 2. Do not use optical instruments to look at the pick up lens. 3. Do not adjust the preset variable resistor on the pickup lens. 4. Do not disassemble the optical pick up unit. 5. If the optical pick up is replaced, use t

12、he manufacturers specified replacement pick up only. 6. Use of control or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. CAUTION! THIS PRODUCT UTILIZES A LASER. USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER T

13、HAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. 6 SA-PM71SDGN / SA-PM71SDGT 6 Handling Precautions For Traverse Deck The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be c

14、areful of electrostatic breakdown during repair of the traverse deck (optical pickup). Handling of traverse deck (optical pickup) 1. Do not subject the traverse deck (optical pickup) to static electricity as it is extremely sensitive to electrical shock. 2. To prevent the breakdown of the laser diod

15、e, an antistatic shorting pin is inserted into the flexible board (FFC board). 3. Take care not to apply excessive stress to the flexible board (FFC board). When removing or connecting the short pin, finish the job in as short time as possible. (Fig 6.1) 4. Do not turn the variable resistor (laser p

16、ower adjustment). It has already been adjusted. Grounding for electrostatic breakdown prevention 1. Work table grounding. (Fig 6.2) Use the anti-static wrist strap to discharge the static electricity from your body. 2. Work table grounding. (Fig 6.2) Put a conductive material (sheet) or steel sheet

17、on the area where the traverse deck (optical pickup) is place, and ground the sheet. Caution: The static electricity of your clothes will not be grounded through the wrist strap. So, take care not to let your clothes touch the traverse deck (optical pickup). Caution when replacing the Traverse Deck

18、The traverse deck has a short point shorted with solder to protect the laser diode against electrostatics breakdown. Be sure to remove the solder from the short point before making connections.

Its a high-capacity, high-speed storage medium for the digital age.

21、 Incredibly small yet durable, the SD Memory Card is about the size of a postage stamp. It can store all kinds of digital content, like video, still images, music and more! So you can transfer data easily between products with an SD Card slot. The miniSD card The miniSD card was developed to meet in

22、dustry demands for a memory card small enough for todays compact mobile phones. It is about 40% smaller than a Panasonic SD Memory Card, but offers all the benefits-including copyright protection. Each miniSD card comes with an adapter that makes the miniSD card compatible with standard SD-enabled p

23、roducts. Ideal for MPEG2 Video Recording The increasing data volume and expanding range of digital contents require high data reading and writing speeds. Panasonic SD Memory Cards, 256MB1and higher, achieve the data writing speed fast enough to record MPEG2 video in fine mode. Compact & Slim The SD

24、Memory Card measures a mere 0.94 x 1.26 x .08 (24mm x 32mm x 2.1mm). Its slim, compact design promotes easy handling-an important factor for moving between different SD-compatible products. Our SD Memory Cards are small enough to be used in select mobile phones and PDAs, as well as many other compac

25、t or multi-functional products. Large Capacity SD Memory Cards are currently available in several capacities up to 1GB2. Be on the lookout in the near future for 2GB2and 4GB2 cards. This kind of large capacity is essential for use with various digital content types, especially high-quality MPEG2 vid

26、eo. Fast Access Providing quick response and effortless handling of digital content, SD Memory Cards 256MB1and higher can write data fast enough to record high-quality MPEG2 video in fine mode. Copyright Protection The copyright protection technology used for the SD Memory Card, Content Protection f

27、or Recordable Media (CPRM), is the key to enabling a new distribution system for music and other commercial media. CPRM assures a high level of protection against illegal copying and was developed by 4C (The digital contents copyright protection technology licensing organization of IBM, Intel, Matsu

28、shita, and Toshiba.). This protection is enhanced in the SD Memory Card through the use of key revocation technology that is built into the card. The 13 SA-PM71SDGN / SA-PM71SDGT cards control circuitry allows data to be read and written, in its protection area only when appropriate external devices

29、 are detected. Copying data (checking-out) from a PC to an SD Memory Card is restricted to three copies in compliance with the SDMI specification.
