• To make the LCD active, briefly press the power button

• To exit this mode, briefly press the power button on the device.

Your Overdrive is turned off, turn the device on:

2. Press the power button on the device for approximately two seconds
3. Wait a few minutes and refresh the networks list; it may take a few seconds for your computer to recognize the device
