You have a digit limit set on the cash button. It has been programmed to allow only a small amount to be paid via cash. You need to look up the codes for digit limit (HALO) in your manual and it will guide you through the processes for setting a digit limit on the cash button. If you have lost the manual, one of the users has one listed here:

Remove the digit limit. Theres a code in the manual somewhere to remove limit on cash key
