Troubleshoot a POS that is slow or lagging, including slow screen loads, delayed response, and transaction delays.

This is usually caused by a software issue that a reboot can fix.

You may see one or more of the following:

There is a noticeable delay between tapping and the POS responding.
Transactions take longer than usual to complete.
Make sure there are no active transactions going on.
Let any customers in the queue know the register will be briefly unavailable.
Press and hold the Reset button on the register.
The Reset button is usually near the status display that shows A9.
If that does not work, unplug the POS power cable from the battery backup.
Wait 2 minutes.
Plug the power cable back in.
Wait for the POS to fully restart.
Test the POS.
