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 err or 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(Electrostaticall y 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-stat i c 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.

1) Launch Fenrir by clicking on the icon on the desktop

- SVH (Fenrir_Home) : It uses Home binary which does not have user data area in the memory when
flashed to a device. (Keep user data)

- SVC (Fenrir_Factory) : It uses Factory binary which erases all user data in the memory when flashed to a
device. (Clear user data)

- SVA (Fenrir_All) : It uses Factory and Home binaries. you can download Home and Factory binary in a
PC(but requires double HDD storage and NW traffic)

2) Input ID & password
※You need to reset the ID information in case of PC change and format and repair, hard disk change
