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 mustbe used during servicing of the unit.1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away fromthe 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 performance of procedures other than those specified herein may result inhazardous radiation exposure.WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/orplastic (where applicable) components may also contain traces of chemicals found by the California Health andWelfare 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 FORANY REASON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumesor expose eyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your handsbefore handling food.RadioFans.CN 收音机爱 好者资料库DVR-S60/NX-SW60DVR-S60NX-SW603Laser Emitting conditions:1) When the Top Cover is removed, and the STANDBY/ON SW is turned to the ON position, the laser component willemit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate throughthe lens of the laser pick-up unit. Do not attempt any servicing during this period!If no disc is detected, the laser will stop emitting the beam. When a disc is set, you will not be exposed to any laseremissions.2) The laser power level can be adjusted with the VR on the pick-up PWB. However, this level has been set by the factoryprior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in thismanual. Adjustment of this control can increase the laser emission level from the device.Laser Diode PropertiesType:Semiconductor laser GaAAlAsWave length:650 nm (DVD)790 nm (CD)Output Power:CLASS 11mW (DVD)0.5mW (CD)VARO!: AVATTAESSA JA SUOJALUKITUS OHITETTAESSA OLET ALTTIINA NKYMTTMLLELASER-STEILYLLE.

Reverseengineering or disassembly is prohibited.qwrwttrwyetThe laser diode in the traverse unit (optical pickup) may be damaged due to static electricity from clothes or the humanbody. Use caution to prevent electrostatic damage when servicing or handling the laser diode.1. Grounding for electrostatic damage prevention1. Worktable groundingPut a grounded conductive material (sheet) or iron sheet on the area where the optical pickup is placed.2. Human body groundingUse an anti-static wrist strap to discharge the static electricity from your body.2. Handling of the optical pickup1. To prevent damage to the optical pickup replacement parts during transportation and before installation, both endsof the laser diode are short-circuited. After installing the new part, remove the short circuit according to the correctprocedure 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 thelaser diode.3. Handling Precautions for the Traverse 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 not be adjusted. Do not turn the resistor.1MConductive material(sheet) or steel sheetAnti-static wrist stripDVR-S60/NX-SW60DVR-S60NX-SW605The DVX-S60 is composed of the DVR-S60 and the NX-SW60.I SYSTEM COMPOSITION / 構成PHONESSTANDBY/ONFM MODETUNINGSURROUNDBASSMUSICINPUTPRESETMEMORYVOLUMENX-S60SNX-S60SNX-S60CSW-S60DVR-S60NX-SW60M DVR-S60 (U, C, R, A, T, K, J models)I FRONT PANELSM DVR-S60 (B, G models)DVR-S60/NX-SW606DVR-S60NX-SW60M SW-S60M U, C, R, A, T, K modelsI REMOTE CONTROL PANELSM B, G modelsM J model初期設定 開閉電源調整時計FM消音 音量画面表示字幕音声 DVR-S60JV984410DVR-S60/NX-SW60DVR-S60NX-SW607I REAR PANELSM DVR-S60 (U, C models)M DVR-S60 (R model)M DVR-S60 (A model)M DVR-S60 (G, B models)DVR-S60/NX-SW608DVR-S60NX-SW60M DVR-S60 (T model)M DVR-S60 (K model)M DVR-S60 (J model)M SW-S60DVR-S60/NX-SW60DVR-S60NX-SW609I SPECIFICATIONS / 参考仕様AMPLIFIER SECTION / 部 Output Power / 実用最大出力 （EIAJ ）FRONT L/R, CENTER, SURROUND L/R1 kHz, 10% THD, 8 . . . . . . . . . . . . . . . . . . 35 WSUBWOOFER100 Hz, 10% THD, 8 . . . . . . . . . . . . . . . . . 40 WU, C modelsFRONT L/R, CENTER, SURROUND L/R1 kHz, 0.9% THD, 8 . . . . . . . . . . . . . . 30 WSUBWOOFER100 Hz, 0.9% THD, 8 . . . . . . . . . . . . . 35 W Inputs / 入力端子VIDEO 1 (RCA)AUDIO . . . . . . . . . . . . . . . . . . . . . . . . . . .
