TX Power tuning

This tuning must be done in all three bands.
Note: TX Power tuning must be done with a peak power meter, e.g. Anritsu model ML2408A
with Anritsu Peak Power Sensor MA2442A and a suitable attenuator.
The use of a spectrum analyser or the power meter in GSM testers is likely to cause larger
error than the use of a dedicated power meter and might cause the phone to be non-
compliant with GSM specifications.
Connect a calibrated powermeter to the RF connector of the phone.
Set operating mode of the phone to Local.
Select
Wait until the TX Power Level Tuning window pops up. Press Start.
TX Power Level Tuning procedure begins from EGSM900 and continues automatically to
GSM1800 (PCS/PCN) and GSM1900 (PSCS).
