    Hi, I have a similar problem in that we have been given a Casio CE-3700 cash register and we just get error messages all the time. From reading your replies to other problems, I think this is a battery problem. We don't have a manual, so need to know where the battery is located please? I cannot find any diagrams or such on the net to help. Thanks in advance.

These machines are really good machines. However they need good power as well. Depending on how long the machine has been used you may have a bad battery . But right now it needs the mac code

12001 sub

then wait for the machine to cycle and after its been plugged in for about 2 days unplug it let it set for a couple of hours and see if it comes back if its still there the battery is probably fine.

It sounds like this machine has a faulty battery. If the problem happened after a power cut, or the machine was stored, then this problem can occur. You will need to fully reset the RAM and start again. I wouldn't advise this until you have changed the battery. If you want to do it yourself, contact a Casio dealer and order a battery for it. Then open the register and plug the new battery in and get back to me. I can help you to clear it and recover the decimal places.
