1. Safety Precautions
1-1
This Document can not be used without Samsung's authorization
1-1. Repair Precaution
zRepair in Shield Box, during detailed tuning. Take specially care of tuning or test, because specificity
of cellular phone is sensitive for surrounding interference(RF noise).
zBe careful to use a kind of magnetic object or tool, because performance of parts is damaged by the
influence of magnetic force.
zSurely use a standard screwdriver when you disassemble this product, otherwise screw will be worn
away.
zUse a thicken twisted wire when you measure level.
A thicken twisted wire has low resistance, therefore error of measurement is few.
zRepair after separate Test Pack and Set because for short danger (for example an overcurrent and
furious flames of parts etc) when you repair board in condition of connecting Test Pack and tuning on.
zTake specially care of soldering, because Land of PCB is small and weak in heat.
zSurely 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 charger.
zDon'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.

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.
zRemove static electricity remained your body before you touch semiconductor or parts with
semiconductor. There are ways that you touch an earthed place or wear static electricity prevention
string on wrist.
zUse earthed soldering steel when you connect or disconnect ESD.
zUse soldering removing tool to break static electricity. , otherwise ESD will be damaged by static
electricity.
zDon't unpack until you set up ESD on product. Because most of ESD are packed by box and
aluminum plate to have conductive power,they are prevented from static electricity.
zYou must maintain electric contact between ESD and place due to be set up until ESD is connected
completely to the proper place or a circuit board.
