11、PERSONNEL 1. Critical Components Information Components having special characteristics are marked Z and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to ve

12、rify that all exposed conductive surfaces are properly insulated from supply circuits. GMeter impedance should be equivalent to 1500 ohms shunted by 0.15F. GLeakage current must not exceed 0.5mA. GBe sure to test for leakage with the AC plug in both polarities. WARNING: Laser Safety This product con

13、tains a laser beam component. This component may emit invisible, as well as visible radiation, which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must be used during servicing of the unit. 1) When testing and/or repairing any component within th

14、e product, keep your eyes and skin more than 30 cm away from the laser pick-up unit at all times. Do not stare at the laser beam at any time. 2) Do not attempt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual. 3) CAUTION : Use of controls, adjustments or pe

15、rfor- mance of procedures other than those specified herein may result in hazardous radiation exposure. WARNING: CHEMICAL CONTENT NOTICE! The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also co

16、ntain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER! Avoid prolonged, unprot

17、ected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food. Laser Emitting conditions: 1) When the Top

18、Cover is removed, and the STANDBY/ ON SW is turned to the ON position, the laser component will emit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through the lens of the laser pick- up unit. Do not attempt any servicing during this per

19、iod! If no disc is detected, the laser will stop emitting the beam. When a disc is loaded, you will not be exposed to any laser emissions. 2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factory prior to shipping from the factory. Do n

20、ot adjust this laser level control unless instruction is provided elsewhere in this manual. Adjustment of this control can increase the laser emission level from the device. 警告：安全対策 本機光線放射部品搭載。 部品放射光線目損傷起。 光線目及肌保護、本機 修理作業中下記注意厳守。 1） 時修理時、目及肌光 30c以上離。場合 光線見。 2） 光再調整及分解 。 3） 上指定以外制御、調 整、手順光線照射結果招恐 。 放

31、rized by Macrovision Corporation, and is intended for home and other limited viewing uses only unless otherwise authorized by Macrovision Corporation. Reverse engineering or disassembly is prohibited. q w r w t t r w y e t The laser diode in the traverse unit (optical pickup) may be damaged due to s

32、tatic electricity from clothes or the human body. Use caution to prevent electrostatic damage when servicing or handling the laser diode. 1. Grounding for electrostatic damage prevention 1. Worktable grounding Put a grounded conductive material (sheet) or iron sheet on the area where the optical pic

33、kup is placed. 2. Human body grounding Use an anti-static wrist strap to discharge the static electricity from your body. 2. Handling of the optical pickup 1. To prevent damage to the optical pickup replacement parts during transportation and before installation, both ends of the laser diode are sho

34、rt-circuited. After installing the new part, remove the short circuit according to the correct procedure in this service manual. 2. Do not use a tester to check the laser diode in the optical pickup. The power supply in the tester will damage the laser diode. 3. Handling Precautions for the Traverse

35、 Unit (Optical Pickup) 1. Handle the traverse unit (optical pickup) gently, as it is an extremely high-precision assembly. 2. The flexible cable lines may break if an excessive force is applied to it. Use caution when handling the cable. 3. The semi-fixed resistor for laser power adjustment should n

36、ot be adjusted. Do not turn the resistor. 1M Conductive material (sheet) or steel sheet Anti-static wrist strap DVR-S300/NX-P301/NX-P302 5 DVR-S300 NX-P301/NX-P302 I SYSTEM COMPOSITION / 構成 The DVX-S301 consists of the DVR-S300 and the NX-P301.
