I have a Sanyo ECR-4000/ECR-4000F cash register and i accidentally put my elbow on the key panel and now it has come up with an error message 07-29 and i cannot do anything with it - can you please help?

Please consult the user manual that was included with your cash register for exact instructions.

The item seems to be a limited run (they stopped making it because it had too many issues) or extremely old, so there is no information available on your unit.

Good luck.
