Heed the cautions!Spots requiring particular attention when servicing, suchas the cabinet, parts, chassis, etc., have cautions indicatedon labels or seals. Be sure to heed these cautions and thecautions indicated in the handling instructions. Caution concerning electric shock!(1) An AC voltage is impressed on this set, so touching in-ternal metal parts when the set is energized couldcause electric shock. Take care to avoid electric shock,by for example using an isolating transformer andgloves when servicing while the set is energized, un-plugging the power cord when replacing parts, etc.(2)There are high voltage parts inside. Handle with extracare when the set is energized. Caution concerning disassembly andassembly!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 aremoved across 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 par-ticular, for the important safety parts that are marked z onwiring diagrams and parts lists, be sure to use the desig-nated parts. Be sure to mount parts and arrange thewires as they were originally!For safety reasons, some parts use tape, tubes or other in-sulating materials, and some parts are mounted away fromthe surface of printed circuit boards. Care is also taken withthe positions of the wires inside and clamps are used tokeep wires away from heating and high voltage parts, sobe sure to set 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 po-sitions, inspect that no parts around the area that has beenserviced have been negatively affected, conduct an insu-lation check on the external metal connectors and betweenthe blades of the power plug, and otherwise check thatsafety is ensured.(Insulation check procedure)Unplug the power cord from the power outlet, disconnectthe antenna, plugs, etc., and turn the power switch on. Us-ing a 500V insulation resistance tester, check that the in-sulation resistance between the terminals of the powerplug and the externally exposed metal parts (antenna ter-minal, headphones terminal, microphone terminal, inputterminal, etc.) is 1M or greater. If it is less, the set mustbe inspected and repaired.Concerning important safetypartsMany of the electric and structural parts used in the sethave special safety properties. In most cases these prop-erties are difficult to distinguish by sight, and using re-placement parts with higher ratings (rated power andwithstand voltage) does not necessarily guarantee thatsafety performance will be preserved. Parts with safetyproperties are indicated as shown below on the wiring dia-grams and parts lists is this service manual. Be sure to re-place them with parts with the designated part number.(1) Schematic diagrams . Indicated by the z mark.(2) Parts lists . Indicated by the z mark.Using parts other than the designatedparts could result in electric shock, fires orother dangerous 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 thepower cord is less than 460 kohms, the unit is defective.CAUTIONCAUTIONRadioFans.CN 收音机爱 好者资料库3AVR-2309CI/AVR-889、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 z 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 以上確認。 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 z 表示。(2) 部品表 z 表示。指定部品異使用場合、感電、火災危険生恐。注意注意4AVR-2309CI/AVR-889DIMENSION AVR-2309CI/AVR-889 model 5AVR-2309CI/AVR-889WIRE ARRANGEMENTIf wire bundles are untied or moved to perform adjustment or parts replacement etc., be sure to rearrange them neatly asthey were originally bundled or placed afterward.Otherwise, incorrect arrangement can be a cause of noisegeneration.Wire arrangement viewed from the topBack Panel sideFront Panel side整形図調整部品交換等、類結束移動場合、作業完了時点整形。正整形発生原因。上面整形6AVR-2309CI/AVR-889CAUTION IN SERVICINGInitializing AV SURROUND RECEIVER/AM-PLIFIERAV SURROUND RECEIVER/AMPLIFIER initialization should be performed when the com, peripheral parts of com, and Digital P.W.B. are replaced.1. Switch off the unit.2. Hold the following INPUT MODE button and SPEAKERS button, and switch on the unit.3. Check that the entire display is flashing with an interval of about 1 second, and release your fingers from the 2 but-tons and the microprocessor will be initialized.Note:If step 3 does not work, start over from step 1. All user settings will be lost and this factory setting will be recovered when this initialization mode.So make sure to memorize your setting for restor-ing after the initialization.About RS-232C communicationsRS-232C communications are not possible when Z4 is dis-played on the FL display.Press and hold in the STATUS and buttons for over 3 seconds with the power turned on to turn the Z4 display off.
