Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
When a cash register locks up, it gets frustrating for sure. I hope I can help solve the problem, though.
I am currently looking up specifics on that particular error message. Expect another posting to this case within 5 minutes or so, and thank you for your patience.
My first suggestion is, to try pressing the CLEAR button, that in the example I found, is located just above the
button. That should stop the beeping alarm.
This happens (if the register is not in a 'broken' state) when you (or the register's operator) try to enter a decimal point into an amount you're ringing up. The decimal point inserts itself. You just need to type in the numbers, for example:
9 . 9 5
which last is what produces the 'sequence error'.
Does that clear up the problem?
Do you know how the error was produced? Another way of producing that error is to turn the key from the Reg position too early, before the transaction is completed, which also produces the error and the beep.
Turn the key back to REG again, complete the transaction, and try again, if that's how it came about, I suggest.
How about the CLEAR button? above the '1' button, or wherever it is on the ER380M.
If the key has a RST position, try turning to the RST position, see if it stops the annoying beep.
Then I regret that I do not know what causes the beep and the sequence error, nor what to do about it, aside from turning the register Off for a while, and trying it again.
Would you like a chance at other advice, from a different Expert? at no additional charge, of course.
I have no such intention.
I have Opted Out, opening the case to other Experts in this category. I hope one of them will have further advice for you on this case.
