1. Safety Precautions

1-1. Repair Precaution

― Repair in shield box during detailed tuning.

Take specially care of tuning or test because the specification of mobile phone is sensitive for

surrounding interference(RF noise).

― Be careful to use a kind of magnetic object or tool because performance of parts is damaged by

the influence of the magnetic force.

― Surely use a standard screwdriver when you disassemble this product.

― Use a thicken twisted wire when you measure level because a thicken twisted wire has low

resistance.

― Repair after separate test pack and set because of short danger (for example an overcurrent and

furious flames of parts etc) when you repair the board in condition of connecting Test Pack and

tuning on.

― Take specially care of soldering iron because the board of the PCB is small and weak in heat.

― Surely tune on/off while using AC power plug because a repair of battery charger is dangerous

when tuning ON/OFF PBA and Connector after disassembling the charger.

― Don't use the unauthorised materials except for the replacement registered on SEC System.

Otherwise the engineer isn't charged with issues that you don't keep.

Safety Precautions

1-2. ESD(Electrostatically Sensitive Devices) Precaution

Several semiconductors may be damaged easily by static electricity. Such parts are called by ESD

(Electrostatically Sensitive Devices), for example IC,BGA chip etc. Read Precaution below.

Protect you from ESD damage by static electricity.

― Remove electrical charges emitted by the human body before you touch semiconductors or parts.

There are ways that you touch an earthed place or wear static electricity prevention string on wrist

to prevent these problems.

― Use a earthed soldering steel when you connect or disconnect ESD.

― Use a soldering removing tool equipped with static electricity isolation.Otherwise ESD will be

damaged by static electricity.

― Don't unpack product until you set up ESD in the product. Because most of the ESD is packed by

box and aluminum plate to have conductive power, it is prevented from static electricity.

― You must maintain electric contact between ESD and a part to be set up until ESD is connected

completely to the proper place or a circuit board.
