1. Safety Precautions

1-1. Repair Precaution

Repair 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).


Be careful of using any kind of magnetic object or tool,
because performance of parts is damaged by the influence of magnetic force.


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


Use a thick twisted wire when you measure level.
A thick twisted wire has low resistance, therefore, a chance of measurement error is low.


Repair after separate Test Pack & Set because of 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.


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


Surely turn on/off the phone while using AC power plug, because a repair of battery
charger is dangerous when you turn 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. 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 as following:


Remove remaining static electricity on your body before you touch semiconductor or parts with
semiconductor. Please touch an earthed place or wear static electricity
prevention string 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
static electricity.


Don't unpack until you set up ESD on product. Because most of ESDs are packed in box and
aluminum plate to have conductive power to avoid static electricity.


You must maintain electric contact between ESD and plate until ESD is connected
completely to the proper place or a circuit board.
