To enter the diagnostics screen:
- Reset the device. (Use a paperclip to press the button in the hole on the back)
- Then hold down three buttons: "on/off" "zoom" and "menu".
- When you see the Logo screen let go of "on.off".
- Keep holding the "zoom" and "menu" keys until you see a 16 item screen.
It's tricky, so it may take a couple of tries.
