Wait until the TX Power Level Tuning window is popped up.
Connect a calibrated power meter to the RF connector of the phone.
Press <Start>

The setup should now look like this:
Adjust the bold marked power coefficients and the base level according to the target values.
The power levels may differ from the target power levels mentioned in Phoenix.
Make sure that the output power for Power Level 5 is equal or lower than 1dB below the satu-
ration output power. Determine the saturation power by setting the DAC value to its maximum,
for example, adjust the DAC Value to 32.3dBm for Power Level 5 if the saturation output power
is only 33.3dBm.
Check if all levels match the target values, correct if necessary and then press < Save & Con-
tinue >.
