3-when i understand that is rx and tx problem???

3/1The most problems of TX are(when you power on the

phone, signal is well but..before the light is off,

signal shut down

3/2 The most problems of RX are (when you switch on

the phone and you have not signal

I DONT KNOW IF YOU UNDERSTAND THE DIFERENCE OF 2 CAUSES?

ANYWAY THESE ARE IN GENERAL

4- Whitch parts of nokia are RX and TX?

4/1- PA (power amplificator)is only TX(trasmiter)

4/2- DUBLEXER is RX and TX too

PA AND DUBLEXER EXEPT THE SIGNAL THEY CAUSE MOST OF

PROBLEMS WHEN NOKIA SHUT DAWN WHEN MAKE A CALL

4/3 HAGAR -is RX and have a little part of TX but 80%

of received signal is hagar

of signal and when the phone shut dawn inormaly

you must listen the ring of the phone if it is

too slowly 32.768khz must be change

4/6 CCONTI TRASMIT ELECTRICITY ALL NOKIA PARTS

4/7 FLASH IC cause most of contact service in nokia
