1. Safety Precautions

1-1. 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 magnetic 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.

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.

●

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.

6-3. Tx Power Tune up Procedure

-GMSK

1) Procedure:
a. Calibraion equipment HP8960 and the cell phone are connected

through RF cable.

b. Target power ( required power level according to the specification

which should be set by calibration program) is set to equipment as

power level (ex: GSM 5 level is 32.5 dBm).
c. Activate phone in Tx_Mode_Only.
d. HP8960 equipment measures transmitted power through rf test cable

from the phone and reports measured level to calibration program.

Test Command & Test Procedure

e. The program compares measured power with the target power.
f. The calibration program decides power code which is defined in

advance in the program and writes the codes to the flash memory in

the phone.

2) Target value is defined according to the value of GSM specification.
See the TX power level definition table below.

3) Target values of the peak level of the phone are set normally in

conducted mode

-GSM8505level:32.5dBm

- EGSM900 5 level : 32.5dBm

- DCS 0 level : 2 9.5dBm

- PCS 0 level : 29.5dBm (Tolerance : -2dB ~ +1dB )

4) Accuracy
All the TX level from the phone after tuned-up satisfy the GSM
specification

5) TX ramp mask specification applied to the calibration program :

1) Procedure:
a. Calibraion equipment HP8960 and the cell phone are connected

through RF cable.

b. Target power ( required power level according to the specification

which should be set by calibration program) is set to equipment as

power level (ex: GSM 8 level is 27 dBm).
c. Activate phone in Cont_8psk_Tx_Mode_Only.
d. HP8960 equipment measures transmitted power through rf test cable

from the phone and reports measured level to calibration program.
e. The program compares measured power with the target power.
f. The calibration program decides power code which is defined in

advance in the program and writes the codes to the flash memory in

the phone.

2) Target value is defined according to the value of EGPRS specification.
