Be sure to heed these cautions and the cau-tions indicated in the handling instructions.Caution concerning electric shock!(1) An AC voltage is impressed on this set, so touching inter-nal metal parts when the set is energized could causeelectric shock. Take care to avoid electric shock, by for ex-ample using an isolating transformer and gloves whenservicing while the set is energized, unplugging the powercord when replacing parts, etc.(2)There are high voltage parts inside. Handle with extra carewhen the set is energized.Caution concerning disassembly and assembly!Though great care is taken when manufacturing parts fromsheet metal, there may in some rare cases be burrs on theedges of parts which could cause injury if fingers are movedacross them. Use gloves to protect your hands.Only use designated parts!The sets parts have specific safety properties (fire resis-tance, voltage resistance, etc.). For replacement parts, besure to use parts which have the same properties. In particu-lar, for the important safety parts that are marked ! on wiringdiagrams and parts lists, be sure to use the designated parts.Be sure to mount parts and arrange thewires as they were originally!For safety reasons, some parts use tape, tubes or other insu-lating materials, and some parts are mounted away from thesurface of printed circuit boards. Care is also taken with thepositions of the wires inside and clamps are used to keepwires away from heating and high voltage parts, so be sure toset everything back as it was originally.Inspect for safety after servicing!Check that all screws, parts and wires removed or discon-nected for servicing have been put back in their original posi-tions, inspect that no parts around the area that has beenserviced have been negatively affected, conduct an insulationcheck on the external metal connectors and between theblades of the power plug, and otherwise check that safety isensured.(Insulation check procedure)Unplug the power cord from the power outlet, disconnect theantenna, plugs, etc., and turn the power switch on. Using a500V insulation resistance tester, check that the insulation re-sistance between the terminals of the power plug and the ex-ternally exposed metal parts (antenna terminal, headphonesterminal, microphone terminal, input terminal, etc.) is 1M orgreater. If it is less, the set must be inspected and repaired.Concerning important safety partsMany of the electric and structural parts used in the set havespecial safety properties. In most cases these properties aredifficult to distinguish by sight, and using replacement partswith higher ratings (rated power and withstand voltage) doesnot necessarily guarantee that safety performance will be pre-served. Parts with safety properties are indicated as shownbelow on the wiring diagrams and parts lists is this servicemanual. Be sure to replace them with parts with the designat-ed part number.(1) Schematic diagrams . Indicated by the ! mark.(2) Parts lists . Indicated by the ! mark.Using parts other than the designated partscould result in electric shock, fires or otherdangerous situations.SAFETY PRECAUTIONSThe following check should be performed for the continued protection of the customer and service technician.LEAKAGE CURRENT CHECKBefore returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassisresistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the powercord is less than 460 kohms, the unit is defective.CAUTIONCAUTION、点検時注意願。注意事項守！特注意必要個所、部品、捺印注意事項表示。 注意書取扱説明書注意事項必守。感電注意！(1) 、交流電圧印加通電時内部金属部触感電。従通電時、絶縁使用手袋着用、部品交換、電源抜感電注意。(2) 内部高電圧部分、通電時取扱十分注意。分解、組立作業時注意！板金部品端面、部品製造時充分管理、 板金端面鋭利箇所有、 部品端面触指動怪我場合十分注意作業下。 手保護手袋着用。指定部品使用！部品難燃性耐電圧安全上特性持。従交換部品、使用同特性部品使用。特配線図、部品表 ! 印指定安全上重要部品必指定使用。部品取付配線引、 元！安全上、絶縁材料使用、基板浮取付部品。 内部配線引発熱部品高圧部品接近配慮、 必元。後安全点検！取外、部品、配線元、 個所周辺劣化点検、外部金属端子部、電源刃間絶縁、安全性確保確認。（絶縁方法）電源電源抜、 外、電源入。500V 絶縁抵抗計用、電源端子外部露出金属部端子、端子端子、入力端子間、絶縁抵抗値 M 以上、値以下点検修理必要。安全上重要部品本機使用多電気部品、 機構部品安全上、 特別特性持。 特性場合、外観判別、部品高定格（定格電力、耐圧）持使用安全性維持、限。安全上特性持部品、配線図、 部品表表示必指定部品番号使用願。(1) 配線図 ! 表示。(2) 部品表 ! 表示。指定部品異使用場合、感電、火災危険生恐。注意注意RadioFans.CN 收音机爱 好者资料库3AVR-1707/1507/687/587/487DIMENSION21717279.356.200244.5339.5316.316.5017221715131.5170.54AVR-1707/1507/687/587/487CAUTION IN SERVICINGInitializing AV SURROUND RECEIVERAV SURROUND RECEIVER initialization should be performed when the com, peripheral parts of com, and Digital P.W.B. are replaced.1.
