Audio Section
MIC Circuit
MIC must have a bias voltage in order to operate. When MIC is in good condition but loop MIC has no
echo, then you need to check the basic bias voltage signal of the MICBIASP and MICBIASSP, the
language signals of the RECEIVER and MIC also need to be checked.
Receiver Circuit

Speaker
Circuit
The audio PA (in SC6820) driveSpeaker directly through Filter and ESD protected network,.
Headset Loop
Headset loop includes two signals: Headset speaker and MIC，If the headset fitting were in good condition,
when the headset plug in, it appears abnormal, such as: The Headset speaker has no sound、the MIC is
invalid. All this need to check the access conditions of the circuit blow:

Safety Precautions
Repair Precaution
Repair in Shield Box, during detailed tuning.
Take specially care of tuning or test,
because specipicty 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 by the influence of manetic
force.
Surely use a standard screwdriver when you disassemble this product,
otherwise screw will be worn 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 overcurrent and furious flames of parts etc) when you repair
board in condition of connecting Test Pack and tuning 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 dangerous when tuning ON/OFF PBA and Connector after
disassembing 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.
ESD(Electrostatically Sensitive Devices)
Precaution
Several semiconductor may be damaged easilly by static
electricity. Such parts are called by ESD(ElectrostaticallySensitive
Devices),for example IC,BGA chip etc. Read Precautionbelow.You
can prevent from ESD damage by staticelectricity.
Remove 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.
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 ESD are packed by box and aluminum 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 is connected completely to the proper
place or a circuit board
