This is the replacement operator display for the SPS-300 series cash register which includes models SPS-320, SPS-340 and SPS-345. We suggest doing some trouble shooting before you just assume your current display has failed. In our experience it is rarely the display and is related to operator error or an accident and can be solved quickly without parts.
If you have decided your display is in fact bad make certain you back up your register and unplug before attempting the replacement, which is pretty easy.
