General instructions for tuning
Connect the phone to a PC, which has Phoenix Service Software and a dongle installed, using 
either
• repair jig and DAU-9S (RS232) cable or
• repair jig and XCS-4 cable via FPS-8 flash box or
• DAU-9T cable (RS232).
Connect the phone to a power supply (DC voltage of 3.6V, min. current of 3A) and switch the 
phone on.
Start Phoenix Service Software and open FBUS connection.
Select <Scan Product> (Ctrl-R  or in menu file < Scan Product>). 
Wait until the phone information is shown in the lower right corner of the screen.
Set operating mode to <Local>.
NOTE: PHOENIX automatically selects the product (phone) by scanning when using the CCS-
dongles, e.g. PKD-1CS or PKD-1. This means all commands 
SelectScan ProductCtrl-R
as mentioned in this document are irrelevant ! 
NOTE:  The screenshots of Phoenix windows displayed in this document showing RH-37, are 
also valid for RM-31.

RF tuning after repairs
Following tunings have to be performed after repairs:
• Repairs in the TX part will require "TX Power Level Tuning". 
• When component replacements around the modulator area (RF path from UEM 
via RF ASIC to RF PA) have been done, "TX IQ Tuning" is additionally required.
• In general, repairs in the RX front-end always require "RX Calibration" and  “Rx 
Band Filter Calibration” for all three bands.
• Repairs in the PLL circuit always require "RX Calibration" of the low band 
(GSM850).
• If the RF ASIC was replaced all calibrations mentioned above have to be carried 
out.
