I operate a calibration company. Recently I cam across Encore 500S’s with version 1.8.00 software. The F1 button would not allow me to enter a password and get into the programming to view net/gross volumes and enter calibration can size. It would beep, but nothing else. I know the keypad works because the totals button would work, and I tried my own known working keypad as well. I have seen this before and the resolution was to unplugged the two wire to the POS and reset the power and wait 8-10 minutes. However I tried this a few times and it didn’t resolve my issue. Have you ever seen this before and do you have any suggestions on how to fix it?
I didn't find the right solution from the internet.
