What to do if nothing is displayed on my Omron HJ-203?

If your Omron Cash Counter's screen is blank, there are several potential causes. First, check the battery polarities (+ and -) and ensure they are correctly aligned. Second, the battery may be weak or exhausted, so try inserting a new 3V lithium battery type CR2032. Lastly, the energy-saving function might be active. Press any button to check the display.
