1. Safety Precautions

1-1

This Document can not be used without Samsung's authorization

1-1. Repair Precaution

― Repair in Shield Box, during detailed tuning. Take specially care of tuning or test, becausespecipicty of cellular 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 bythe influence of magnetic force.

― Surely use a standard screwdriver when you disassemble this product, otherwise screw will beworn away.

― Use a thicken twisted wire when you measure level.A thicken twisted wire has low resistance, therefore error of measurement is few.

― Repair after separate Test Pack and Set because for short danger (for example an overcurrentand furious flames of parts etc) when you repair board in condition of connecting Test Pack andtuning on.

― Take specially care of soldering, because Land of PCB is small and weak in heat.

― Surely tune on/off while using AC power plug, because a repair of battery charger is dangerouswhen tuning ON/OFF PBA and Connector after disassembling charger.

― Don't use as you pleases after change other material than replacement registered on SEC System.Otherwise engineer in charge isn't charged with problem that you don't keep this rules.

Safety Precautions

1-2

This Document can not be used without Samsung's authorization

1-2. ESD(Electrostatically Sensitive Devices) Precaution

Several semiconductor 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.You can prevent from ESD damage by static electricity.

― Remove static electricity remained your body before you touch semiconductor or parts withsemiconductor. There are ways that you touch an earthed place or wear static electricity preventionstring on wrist.

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

― Use soldering removing tool to break static electricity. , otherwise ESD will be damaged by staticelectricity.

― Don't unpack until you set up ESD on product. Because most of ESD are packed by box andaluminum plate to have conductive power,they are prevented from static electricity.

― You must maintain electric contact between ESD and place due to be set up until ESD isconnected completely to the proper place or a circuit board.
