Recommendation for repair actions in the RF- area  
To prevent some additional faults please take care of following recommendations for repairing the RF-area  
Don't use so much flux that it will go through the board and soiled the keyboard area  
Clean after every repair time the rest of the flux from PCB  
Don't make any loose wiring connection on the board  
To change some components it is necessary to remove the shield from the PCB, use matching nozzles for the  
solder machine. Don't cut it partially and solder the "old" part back or make some unqualified work  
Use a new shield after removing  
Low receiver signal strength indicator  
Antenna faulty / wrong - Tuning  
Check the fixed position of the antenna, don't touch the conducting area with the fingers  
Check the antenna spring connector X501, change it if bent  
Check the receiver signal indicator with a new antenna  
Retune the handset  
No Service  
Set first the RF-Generator to a high RF-Level output e.g. –40dBm  
Set the module with wintesla as follow mode: Initialise/ Local mode/ Testing/ RF Controls/ Active unit "RX"/  
Operation Mode "continuous"  
13MHz VCTCXO G701 out of range  
Check the 13MHz reference frequency pin 15 N700 (SUMMA) or pin 2 of G750, a frequency error  
higher +-50Hz can create deviation of the Intermediate frequencies

Check the LNA_AGC voltage 2,8V DC pin 28 N600  
Check the VRX_1 voltage 2,8V pin 15,16,23, 33, 38,45,46 N600  
Check the LNA_OUT frequency pin 23 N600 and input on pin 18, 19.  
An attenuation from aprox. 10-15dBm between signal input and output is normal!  
Check the UHF LO frequency (2036MHz GSM900 CH60) pin 3 N600 approx. –20dBm.  
No frequency deviations are allowed!  
Check the outgoing 71MHz Intermediate Frequency on pin 15, 16 N600  
Check the soldering of N600 or change it  
Z700 / faulty / poor soldering  
Check the 71MHz IF frequency on Z700. The normal attenuation between input and output are 15dBm  
Check the components C701, C704,C149, L701, R701 if the signal amplitude is different between the two lines

check the 13MHz IF on Z701, around 5dBm attenuation between signal-in and signal-out  
check the soldering of Z701 or change it  
check R717, R718, R719, C706 and the line resistance to ground (10Kwith all components)  
G700 UHF Oscillator faulty  
check the UHF frequency on G700 for high spurious or deviation  
check the UHF-VC on pin 21 N700 1,9V-3.2V DC depending of the channel  
check the 5V VCP supply voltage on pin 13, 22 from N700 SUMMA  
check R733 33K, R730 5K6 , R731 2K2, C740 2,2nF  
change the oscillator  
N700 SUMMA faulty / poor soldering  
check the 13MHz reference frequency pin 15 N700. (No frequency deviation higher ±50Hz is allowed!)  
check the power supply voltage VRX_2 2,8V DC pin 35 N600  
check the incoming IF 71MHz pin 37,38 N700  
check the 13MHz IF on pin 30(out),25, 26(in) N700 . The attenuation between input and output are 20dBm  
check the control-lines for the PLL pin 5, 6, 7 from N700 (see the diagrams below)  
check the incoming VHF_LO frequency 464MHz pin 8 N700 if the 13MHz IF are deviated or not exist  
measurable level approximate –20dBm!  
Check the synth. power supply 2,8V DC pin 9, 19 N700 and VCC G700, G702  
Check the VCP 5V DC pin 13, 22 N700  
Check the control voltage for the UHF and VHF oscillator  
(UHF pin 21 control voltage is channel dependent, pin12 2,2V DC on N700)  
Check the soldering of N700 or change it
