    測定リードを、 アンテナ端子やヘッドホンジャックなどの露出金属部 に順番に接触させて抵抗値を測定します。 1.5 kΩ/10W 露出金属部とシャーシとの間に帰路抵抗器が存在する場合、 抵抗計の 指示は1 ~ 5.2 MΩの範囲となります。 この帰路抵抗器が存在しない 場合、 抵抗計の指示は無限大です。 なんらかの異常が認められた場 合は、 受信機をユーザーに返却する前に、 その異常を修復する必要が あります。 Copyright © LG Electronics.

    1. 半導体部品や半導体を使用したアセンブリを扱う直前に、 接地され ていることがわかっている部分に触れて体内に蓄積されている静電 気を放電させます。 または、 市販の放電用リストストラップを装着します。 感電の危険を 防止するために、 テスト中に製品などに通電する場合は、 このストラ ップは外してください。 2. ES 部品を使用した電気系アセンブリを取り外した後、 それをアルミ ホイルのような導電性の表面上に置きます。 これにより、 静電荷の蓄 積が発生せず、 静電気にさらされることもなくなります。 Copyright © LG Electronics. Inc. All rights reserved. - 4 - LGE Internal Use Only Only for training and service purposes...
