Steps
1. Put the phone on the jig on a table.
The area around the phone should be free from objects. Ambient noise should be low so it does not disturb
the test.
2. Start Phoenix service software.
3. From the
File
menu, select Scan Product and check that the correct product version is displayed.
4. Set the phone in test mode.
5. From the Testing menu, select Audio Control.
The
Audio Control
dialogue box is displayed.
6. Audio routing must be turned off before this test. In the
Audio Control
window, select None and click
Activate.
Failing this, several dB of measurement error is created. Check this especially after uplink microphone
tests.
7. In the
Audio Control
window, activate E-ANC Microphone Test.
