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

(GSM900).

• If the RF ASIC was replaced all calibrations mentioned above have to be carried

out.
