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.
