TEST 33
Test 33 tests Antenna Tuning Unit without power.
The TU checks that an ATU is connected and if so, if it is in manual mode and able to
communicate with the TU.
The ATU tests: RAM, Vforward-, Vreflected-, 0 degrees-,
90 degrees-, and temperature-detector.

TEST 34
Test 34 tests battery voltage and power amplifier module. Supply voltage is read from PCB
933/935 and compared with PA module ID. PA ID is performed by a voltage divider and read by
the A/D converter.
