How can I test that the microphones on my Minto is working?

The Minto has a built in microphone test which can be useful to verify that all 4 microphones are working.

1. Power on your Minto.
2. Press the Bluetooth and Vol- buttons pressed simultaneously for 3 seconds.
3. A message should start to play indicating the microphone test is initiated followed by a series of beeps. A messages will now be played in sequence for the 4 microphones (1, 2, 3 and 4), recorded and then finally played back.

If the message isn't played back for one the microphones this indicates that the specific microphone is not working properly.
