Yes Yes No No Yes

Yes No No Yes No

Push the button for power up, is the consumption is about 50mA and connect

with PC?

The consumption is about 50mA and after

down to 0.5mA?

Go to “A”

pag. 4

Replace U900

Are there these voltages? VBoost=5.8v on C921 VBuck=1.9v on L920

RF 5v REG=5v on C933

Replace U800. If the problem persists then

replace U700.

The consumption is about 0.5mA always?

ENDReflash the PCB, switch on?

NO POWER UP

Connect the PCB to Radiocomm with USB’s cable: SKN6371A and supply it with external supply (4.2 v)

NOTE: Should connect a keyboard flex assy (P/N: 8489976N03) to PCB for power up by hand.

Follow procedure of pag. 7

No Yes No Yes

Replace Y805

Replace Y301 Measure on Y301, Is there 32.7KHz´s

signal?

Measure on Y805, Is there 26MHz´s

signal?

“A”

Replace PCB

NOTA If when I connect PCB to external power supply and are a high current (1.5 or 2 A) look

up component hoter than others, desolder that component and connect other again to external power supply and look up hot component again and repeat the procedure.

No Yes

No Yes

Yes No No Yes No

No TX

Measure in J40´s output. Is there the TX signal with

2 dBm power and one current about 360 mA?

Measure in PA´s input (C80 y L80). Is there the Tx´s signal with -8dBm?

Replace U150 (Algae)

Replace U800(Neptune)

and U700 (Flash/Sram)

Is there in L181 TX_CP´s signal?

Replace U50 (PA)

Measure in (U50) PA´s output. Is there the Tx´s

signal with 12dBm?

Replace J40

Measure in J40´s input. Is there the TX signal with 5

dBm power and one current about 360 mA?

Use this procedure to set TX in any band (GSM, DCS, etc). Main difference between setting bands is:

- Set band with Radiocomm. - Set channels (accordingly to band selected) with Radiocomm.

Connect the PCB to Radiocomm with USB’s cable: SKN6371A and supply it with external supply (4.2 v), NOTE: Should connect a

keyboard flex assy (P/N: 8489976N03) to PCB for power up by hand. Put it to transmit with 10 of LEVEL PA and select

00- All zeroes, in window CARRIER, select the band and channel.

No Yes No Yes

Replace U150 (Algae)

Replace FL100

Is there the same signal in the

FL100´s output as the signal’s inject?

Replace U50

Is there the same signal in the FL100´s input as

the signal´s inject?

Use this procedure to set RX in any band (GSM, DCS, etc). Main difference between setting bands is:

- Set band with Radiocomm. - Set channels (accordingly to band selected) with Radiocomm.

Connect the PCB to Radiocomm with USB’s cable: SKN6371A and supply it with external supply (4.2 v) NOTE: Should connect a

keyboard flex assy (P/N: 8489976N03) to PCB for power up by hand. Inject a signal (-50 dBm GSM channel or -50 dBm DCS channel) to

external connector (J40).

NO RX

Procedure flash’s

replacement

FOLLOW THIS PROCEDURE TO REPLACE THE FLASH

AND MICROPROCESOR

REQUIREMENTS: FOR THIS PROCEDURE WE USE, WINDOWS 2000, PST 6.8 or RSD AND Internal RADIOCOMM 7.1.1 or higher

ALWAYS 1. - Download this software with this cable P/N: SKN6371A

R374_G_0E.40.2AI_LP0003_DRM0001_GMMV3xx000AA014_image.shx. 2. - To restore the BD Address (Bluetooth Device Address), with Internal Radiocomm 7.1.1 or higher. - Put the PCB in suspend mode. - Click in “GSM 2” - In STELEM/RDELEM write that information: Bluetooth Address Element ID 00AB

Record # 0001 Record Offset 0000 Length 0006

Data xxxxxxxxxxx*Note

*Note: BD ADDR, can be found at approval label on the rear housing. BD ADDR is unique to each phone. -Click on STELEM

3. - Then restore IMEI, with Radiocomm 7.1.1 or higher:

- Put the PCB in suspend mode. - Click in “GSM 2” - In STELEM/RDELEM write that information: Element ID 0004 Record # 0001 Record Offset 0000 Length 0009

Data xxxxxxxxxxx IMEI *Note

*Note: Example for writing an imei: Pcb´s Imei 3 5 0 9 0 7 2 0 8 0 6 3 0 5 9 For write in Data: 0 8 3 A 0 5 0 9 2 7 8 0 6 0 0 3 9 5 -Click on STELEM 4. - Then restore Subsidy Lock, with Internal Radiocomm 7.1.1 or higher:

- Put the PCB in suspend mode. - Click in “GSM 2” - In STELEM/RDELEM write that information:

Element ID 0348 Record # 0001 Record Offset 0000 Length 0004

Data xxxxxxxxxxx Subsidy Lock *Note

Element ID 0349 Record # 0001 Record Offset 0000 Length 0004

Data xxxxxxxxxxx Subsidy Lock *Note
