Make sure the device is correctly connected to power, and that the latest firmware is installed (see Why does the 'ON' light stay red/orange?).
For proper function, the device needs good GPS reception and must be operated outside with good view of the sky.
Try a factory reset: How do I perform a factory reset on Aurora?
If the problem still persists, connect to the Wi-Fi (if possible): How do I connect to Aurora via Wi-Fi?
Under 'Tools'->'Support', create a support package and send it to 'email@example.com' with a detailed description of what is wrong with the device, and that support package.
