clockwise and decreases as the VOL control is rotated counterclockwise.
Adjust the Headset Adapter's VOX control to fully clockwise and confirm that
the microphone audio is off.
Press the Headset Adapter's ICS PTT button and confirm that microphone
audio is heard in the phones. Repeat this process for the TX PTT button.
