– 2 – DSLR-A500/A550_L3 SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK OR DOTTED LINE WITH MARK ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. ATTENTION AU COMPOSANT AYANT RAPPORT À LA SÉCURITÉ! LES COMPOSANTS IDENTIFIÉS PAR UNE MARQUE SUR LES DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS QUE PAR DES PIÈCES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPLÉMENTS PUBLIÉS PAR SONY. Caution Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type. Dispose of used batteries according to the instructions. Caution 電池の交換は，正しく行わないと破裂する恐れがあります。電池を交換する場合には必ず同じ型名の電池又は同等品と交換してください。使用済み電池は，取扱指示に従って処分してください。 CHEMICALS Some chemicals used for servicing are highly volatile. Their evaporation caused by improper management affects your health and environment, and wastes resources. Manage the chemicals carefully as follows. • Store chemicals sealed in a specific place to prevent from ex- posure to high temperature or direct sunlight. • Avoid dividing chemicals into excessive numbers of small containers to reduce natural evaporation. • Keep containers sealed to avoid natural evaporation when chemicals are not in use. • Avoid using chemicals as much as possible. When using chemicals, divide only required amount to a small plate from the container and use up it. EXTERIOR PARTS Be careful to the following points for plastic parts used in this unit. • Use a piece of cleaning paper or cleaning cloth for cleaning plastic parts. Avoid using chemicals. Even if you have to use chemicals to clean heavy dirt, don’t use paint thinner, ketone, nor alcohol. • Insert the specific screws vertically to the part when installing a plastic part. Be careful not to tighten screws too much. UNLEADED SOLDER This unit uses unleaded solder. Boards requiring use of unleaded solder are printed with the lead free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.) : LEAD FREE MARK Be careful to the following points to solder or unsolder. • Set the soldering iron tip temperature to 350 °C approximately. If cannot control temperature, solder/unsolder at high temperature for a short time. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. • Be sure to control soldering iron tips used for unleaded solder and those for leaded solder so they are managed separately. Mixing unleaded solder and leaded solder will cause detachment phenomenon. SAFETY CHECK-OUT After correcting the original service problem, perform the following safety checks before releasing the set to the customer. 1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges. 2. Check the interboard wiring to ensure that no wires are “pinched” or contact high-wattage resistors. 3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. 4. Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement. 5. Check the B+ voltage to see it is at the values specified. 6. Flexible Circuit Board Repairing • Keep the temperature of the soldering iron around 270 °C during repairing. • Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). • Be careful not to apply force on the conductor when soldering or unsoldering. 各種薬品の取り扱いについて現在使用されている薬品の中には揮発性の高い薬品もあります。それらを不用意に取り扱い蒸発させてしまうと，環境や健康へ影響を与えたり，資源の無駄使いになります。各種薬品は，下記の点に注意して取り扱ってください。・保管場所を定め，高温になったり直射日光の当たらない場所に密閉して保管してください。・小分け（ハンドラップ等）する数は必要最小限に留め，容器による自然蒸発を防いでください。・作業に使用しない時は，必ずキャップ等をして自然蒸発を防いでください。・薬品を使用する回数を極力少なくし，使用する場合は使用する量だけ容器より出して受け皿に残さないようにしてください。樹脂系部品の取り扱いについて本機に使用されている樹脂系の部品は，下記の点に注意して取り扱ってください。・清掃には薬品を使用せず，清掃紙や清掃布を使用してください。やむを得ず汚れがひどくて薬品を使用する場合は，シンナー，ケトン，エーテルは使用しないでください。・各部品の取り付けには指定されたねじを使用し，部品に対して垂直に取り付けてください。また，ねじを締め付ける時は，無理な力を加えないでください。 1. 注意事項をお守りください。サービスのとき特に注意を要する個所については，キャビネット，シャーシ，部品などにラベルや捺印で注意事項を表示しています。これらの注意書き及び取扱説明書等の注意事項を必ずお守りください。 2. 指定部品のご使用をセットの部品は難燃性や耐電圧など安全上の特性を持ったものとなっています。従って交換部品は，使用されていたものと同じ特性の部品を使用してください。特に回路図，部品表に印で指定されている安全上重要な部品は必ず指定のものをご使用ください。 3. 部品の取付けや配線の引きまわしはもとどおりに安全上，チューブやテープなどの絶縁材料を使用したり，プリント基板から浮かして取付けた部品があります。また内部配線は引きまわしやクランパによって発熱部品や高圧部品に接近しないよう配慮されていますので，これらは必ずもとどおりにしてください。 4. サービス後は安全点検をサービスのために取外したネジ，部品，配線がもとどおりになっているか，またサービスした個所の周辺を劣化させてしまったところがないかなどを点検し，安全性が確保されていることを確認してください。 5. チップ部品交換時の注意・取り外した部品は再使用しないでください。・タンタルコンデンサのマイナス側は熱に弱いため交換時は注意してください。 6. フレキシブルプリント基板の取扱いについて・こて先温度を270℃前後にして行なってください。・同一パターンに何度もコテ先を当てないでください。（3回以内）・パターンに力が加わらないよう注意してください。サービス，点検時には次のことにご注意ください。無鉛半田について本機には無鉛半田が使用されています。無鉛半田を使用している基板には，無鉛（Lead Free）を意味するレッドフリーマークがプリントされています。（注意：基板サイズによっては，無鉛半田を使用していてもレッドフリーマークがプリントされていないものがあります）：レッドフリーマーク無鉛半田は，下記の点に注意して使用してください。・半田こてのこて先温度は約350℃に設定してください。温度調節が無理な場合は，高温短時間で作業を行ってください。注意：半田こてを長く当てすぎると，基板のパターン（銅箔）がはがれてしまうことがありますので，注意してください。また，従来の半田よりも粘性が強いため，IC端子などが半田ブリッジしないように注意してください。・半田こてのこて先は，必ず無鉛半田用と有鉛半田用に分けて管理してください。無鉛半田と有鉛半田が混在すると剥離現象が発生してしまいます。 – ENGLISH – – JAPANESE –
