Don't actually know what causes this. Things to try:
1) Press and hold SETUP when you see the remote message.
2) Try another battery.
3) Make sure you do the 8 key on the SECOND startup screen, not the first. It should say "are you sure" or similar.
4) Make sure the connections to the audio boards are good – if it only sees one, it may think it is a DSP7000.
5) If all else fails, you'll have to send it in.
