Hi I have casio se-c450 I press anything it will show E008 it say please sign on I don't know what is that thanks

You should have been given a secret PIN number by your manager to log on to the machine. It won't allow sales without a sign on because it can't be traced to an operator. If you have forgotten the PIN number, you can program a new one. One of the users has a manual here:

How can i clear memory on Casio SE-S300 for new business?

This might be of help. I had a quick browse through it, but couldn't find reset to factory defaults in the contents. I'm sure it will have what you're looking for, though. Good luck.

How do I load data from a database to the sd card for loading into a Casio SE-C450

Haven't worked with that model. Normally you need conversion software but Casio states that you need CSV data. Try saving it in CSV format and then try loading it and see if the register can see it.Make sure you back up the register first as you may corrupt data.

I have a SE-5300 Casio cash register and I want to reset everything.

I think you mean an SE-S300. If so, pull a battery out. Turn key to REG mode. Turn off at wall, then back on. Put battery in. Be aware that this will lose all programming and sales data. You will need to re-program from scratch.
