FM-19 牆壁安裝充電器有聲槽但會移位或脫落

• Screw heads do not engage the keyhole slots
• Screw exposure or spacing is incorrect
• Fasteners are not secured in sound wall material
• Cord strain or pack handling pulls the charger
• Mount is too close to a corner or airflow obstruction

1. The sound charger remains fully engaged and stable during a gentle battery cycle with clear airflow, or it is kept in safe tabletop service.

1. Verify sound supporting material and install appropriate screws to the current official head, engagement, spacing, and exposure requirements.
2. Remount within cord reach and away from corners, heat, and airflow obstructions, with no cord strain.
3. Perform an unloaded hand stability check and then a gentle battery insert/remove test; if the charger moves, return it to tabletop use or obtain qualified installation.
4. Remove the battery, unplug the charger, and take it off the wall; use it on a hard tabletop until the mount is proven secure.
5. Inspect both keyhole slots and the surrounding housing; use FM-18 if any slot or plastic is cracked, enlarged, or broken.
