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.

1. Safety Precautions 1-2. ESD(Electrostatically Sensitive Devices) Precaution Many semiconductors and ESDs in electronic devices are particularly sensitive to static discharge and can be easily damaged by it. We recommend protecting these components with conductive anti-static bags when you store or transport them. Always use an anti-static strap or wristband and remove electrostatic buildup or dissipate static electricity from your body before repairing ESDs. Ensure that soldering irons have AC adapter with ground wires and that the ground wires are properly connected. Use only desoldering tools with plastic tips to prevent static discharge. Properly shield the work environment from accidental electrostatic discharge before opening packages containing ESDs. The potential for static electricity discharge may be increased in low humidity environments, such as air-conditioned rooms. Increase the airflow to the working area to decrease the chance of accidental static electricity discharges.
