We have have ER-150 samsung till. I set the date this morning and then went to serve a customer and it started beeping and now can not use any buttons please can you help
Hi Sarah. The first thing I'd try is setting the mode switch to each mode and press clear (C). So, switch to R mode, press C, switch to X mode, press C etc. If it stops beeping in any mode (other than off) then you have pressed an incorrect button in that mode. If it doesn't stop beeping, you probably have a printer problem. Look for jammed paper or anything stopping the printer from running.
