1. Safety Precautions
1-1. Repair Precaution
Before attempting any repair or detailed tuning, shield the device from RF noise or static
electricity discharges.
Use only demagnetized tools that are specifically designed for small electronic repairs,
as most electronic parts are sensitive to electromagnetic forces.
Use only high quality screwdrivers when servicing products. Low quality screwdrivers can
easily damage the heads of screws.
Use only conductor wire of the properly gauge and insulation for low resistance, because of the low margin
of error of most testing equipment.
We recommend 22-gauge twisted copper wire.
Hand-soldering is not recommended, because printed circuit boards (PCBs) can be easily
damaged, even with relatively low heat. Never use a soldering iron with a power rating of
more than 100 watts and use only lead-free solder with a melting point below 250°C (482°F).
Prior to disassembling the battery charger for repair, ensure that the AC power is disconnected.
Always use the replacement parts that are registered in the SEC system. Third-party replacement parts
may not function properly.
