To power-up the board, perform the following steps below:

2. Connect the HDMI output from the development kit to a display.
3. Connect the Power Adapter to the 12V DC Jack and then press and hold the power button until you
see the Lantronix logo appear on the display (~3 seconds).
4. Plug in a USB mouse to navigate the UI on the HDMI display.

WARNING!
The above steps should be followed in exact sequence when battery is not connected to the
Dev Kit. Failing to do so prevents system from booting. If a battery is not connected, the user
has to always plug in the 12V power source before the USB ADB cable is plugged in.
