41、nect the power cable from the AC outlet.Spread soft cloth or the like and perform the work on it.Use full care as you may be injured by the front grilleor other part.All screws must be tightened securely to prevent airleakage. Check the number of screws and their posi-tions when installing them.When

42、 installing parts, be careful not to have anythingsuch as cables caught between other parts.Make sure that all the removed driver (tweeter) partsare reinstalled at specified positions.I SERVICE PRECAUTIONS / 時注意事項安全対策 製品内部高電圧部分危険。修理際、絶縁性手袋使用安全対策行。 下記箇所電源OFF後電荷残、高電圧維持危険。修理作業前放電用抵抗 （5 k/10 W） 下記箇所端子間接

Be sure to take safety measures dur-ing

44、servicing, such as wearing insulating gloves.Note that positions indicated below are dangerous evenafter the power is turned off because an electric chargeremains and a high voltage continues to exist there.Before starting any repair work, perform discharge by con-necting a discharge resistor (5k-oh

45、ms/10W) between ter-minals at following positions. The time required for dis-charging is about 30 seconds.1. C502 on INPUT (1) P.C.B.2. C523 on INPUT (1) P.C.B.Refer to “PRINTED CIRCUIT BOARDS: INPUT (1)P.C.B.” .Caution for P.C.B. replacementWhen replacing INPUT (1) and INPUT (2) P.C.B.s, be sure to

46、replace them at the same time. Installing either P.C.B. of dif-ferent version from the other may cause failure of operation.Disassembly Procedures as far as P.C.B.s1. 外方a. 13本外、L取外。（Fig. 1）b. 23本外、R取外。（Fig. 1）c. 330本、44本、54本、65本外。 （Fig. 1）d. 後方取外。(Remove parts in the order as numbered.)（番号順部品取外。）P.C
