診断の概要

FM-11 充電は正常だがインジケーターが暗い、固着、または誤表示

考えられる根本原因

  • Indicator lens or printed legend is dirty
  • Bright ambient light masks the indicator
  • LED, lens, or internal indicator connection is failing
  • Indicator-control circuit is latched or damaged

簡単チェック

  1. The indicator clearly matches actual charging and completion, or the charging outcome is normal and the indicator-only fault is routed to service/replacement.

修理プレビュー

  1. If the indicator remains unreliable, stop relying on it and have the complete charger serviced or replaced; do not open the housing.
  2. Unplug the charger, remove the pack, and clean only the outside of the indicator lens and legend with a dry soft cloth.
