SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power
cord is less than 460 kohms, the unit is defective.

DRA-700AE/700AEDAB/500AE

CAUTION

Please heed the points listed below during servicing and inspection.

◎ Heed the cautions!

Spots requiring particular attention when servicing, such as
the cabinet, parts, chassis, etc., have cautions indicated on
labels or seals. Be sure to heed these cautions and the cau­tions 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 cause
electric shock. Take care to avoid electric shock, by for ex­ample using an isolating transformer and gloves when
servicing while the set is energized, unplugging the power
cord when replacing parts, etc.

(2)There are high voltage parts inside. Handle with extra care

when the set is energized.

◎

Caution concerning disassembly and assembly!

Though great care is taken when manufacturing parts from
sheet metal, there may in some rare cases be burrs on the
edges of parts which could cause injury if fingers are moved
across them. Use gloves to protect your hands.

◎ Only use designated parts!

The set's parts have specific safety properties (fire resis­tance, voltage resistance, etc.). For replacement parts, be
sure to use parts which have the same properties. In particu­lar, for the important safety parts that are marked ! on wiring
diagrams and parts lists, be sure to use the designated parts.

◎ Be sure to mount parts and arrange the

wires as they were originally!

For safety reasons, some parts use tape, tubes or other insu­lating materials, and some parts are mounted away from the
surface of printed circuit boards. Care is also taken with the
positions of the wires inside and clamps are used to keep
wires away from heating and high voltage parts, so be sure to
set everything back as it was originally.

◎ Inspect for safety after servicing!

Check that all screws, parts and wires removed or discon­nected for servicing have been put back in their original posi­tions, inspect that no parts around the area that has been
serviced have been negatively affected, conduct an insulation
check on the external metal connectors and between the
blades of the power plug, and otherwise check that safety is
ensured.

(Insulation check procedure)
Unplug the power cord from the power outlet, disconnect the
antenna, plugs, etc., and turn the power switch on. Using a
500V insulation resistance tester, check that the insulation re­sistance between the terminals of the power plug and the ex­ternally exposed metal parts (antenna terminal, headphones
terminal, microphone terminal, input terminal, etc.) is 1MΩ or
greater. If it is less, the set must be inspected and repaired.

CAUTION

Many of the electric and structural parts used in the set have
special safety properties. In most cases these properties are
difficult to distinguish by sight, and using replacement parts
with higher ratings (rated power and withstand voltage) does
not necessarily guarantee that safety performance will be pre­served. Parts with safety properties are indicated as shown
below on the wiring diagrams and parts lists is this service
manual. Be sure to replace them with parts with the designat­ed part number.

(1) Schematic diagrams ... Indicated by the ! mark.

(2) Parts lists ... Indicated by the ! mark.

Concerning important safety parts

Using parts other than the designated parts
could result in electric shock, fires or other
dangerous situations.

サービス、点検時にはつぎのことにご注意願います。

◎注意事項をお守りください！

サービスのとき特に注意を必要とする個所についてはキャ
ビネット、部品、シャーシなどにラベルや捺印で注意事項を
表示しています。これらの注意書きおよび取扱説明書などの
注意事項を必ずお守りください。

◎感電に注意！

(1) このセットは、交流電圧が印加されていますので通電時

に内部金属部に触れると感電することがあります。従っ
て通電サービス時には、絶縁トランスの使用や手袋の着
用、部品交換には、電源プラグを抜くなどして感電にご
注意ください。

(2) 内部には高電圧の部分がありますので、通電時の取扱に

は十分ご注意ください。

◎分解、組み立て作業時のご注意！

板金部品の端面の『バリ』は、部品製造時に充分管理をして
おりますが、板金端面は鋭利となっている箇所が有りますの
で、部品端面に触れたまま指を動かすとまれに怪我をする場
合がありますので十分注意して作業して下さい。手の保護の
ために手袋を着用してください。

◎指定部品の使用！

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。特に配線図、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。

◎部品の取付けや配線の引きまわしは、

元どおりに！

安全上、テープやチューブ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ーによって発熱部品や高圧部
品に接近しないように配慮されていますので、これらは必ず
元どおりにしてください。

◎サービス後は安全点検を！

サービスのために取り外したねじ、部品、配線などが元どお
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、外部金属端子部
と、電源プラグの刃の間の絶縁チェックをおこなうなど、安
全性が確保されていることを確認してください。

（絶縁チェックの方法）

電源コンセントから電源プラグを抜き、アンテナやプラグな
どを外し、電源スイッチを入れます。500V 絶縁抵抗計を用
いて、電源プラグのそれぞれの端子と外部露出金属部［アン
テナ端子、ヘッドホン端子マイク端子、入力端子など］との
間で、絶縁抵抗値が１ MΩ 以上であること、この値以下の
ときはセットの点検修理が必要です。
