Safety Precautions

1.

Repair Precaution

1-1.

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

Hand-soldering is not recommended, because p rinted circuit boards(PCBs) can be easily

gauge twisted copper wire.

22-

damaged, even with relatively low heat. Never useasoldering iron withapower 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 replac
ement parts may not function properly.

Safety Precautions

ESD(Electrostatically Sensitive Devices) Precaution

1-2.

Many semiconductors and ESDs in electronic devices are particularly sensitive to static discha
rge and can be easily damaged by it. We recommend protecting these components with cond
uctive 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.
