CMOS Settings wrong

The message means that the CMOS coin cell battery is exhausted, and so the clock isn't being kept running when the console is unplugged.

It's a standard CR2032 lithium coin cell that you can find in most places.

If you give your local ETC office a call with the console serial number we can talk you through replacing it or send you the instructions.
As this battery should last many years, we can also send you a replacement coin cell free of charge if you would like.

Thanks Richard for such a prompt reply.  At least I know nothing serious is going to happen during a show.  We will get a new battery ASAP.

We power off at the mains whenever the board is not in use - we are prone to thunderstorms and surges (although we have a surge board).  Is it advisable to keep it powered at the mains at all time?
