Adjust the screen contrast on the SAM4s SPS-300 series registers



This happens to be one of the SAM4s troubleshooting calls we get every day. The cashier screen on one of the following models has gone blank. This happens to the SPS-320, SPS-340 and the SPS-345 but the cashier has no idea what caused it or how to fix. The good news is in my experience 99% of the time the cashier has inadvertently adjusted the contrast so much the screen can no longer be read. Good news is there is nothing broken, just adjust the contrast and you are good to go again. Check out the video for the directions. We have all the current models of SAM4s cash register available at discount prices.
