4. USB MODE - Android Operation

4.1 Android Device Setup and Operation

The GROM-MST4 adapter when in USB mode allows you to connect your Android device directly to the GROM-MST4 USB

port. You will need the GROM AALinQ app available on the Google Play store / Android marketplace (search for AALinQ) .

Once you have AALinQ installed on your Android device, you can connect your Android to the USB port using your own or

provided USB Android connector cable.

Depending on the version of your Android software and the phone model, you might need to disable or enable the USB

Debugging option on your phone. If you plugged in your Android phone to the GROM device, and your adapter is not

working, please go to the phone settings and either enable or disable the USB Debugging function.
