  The '[Calendar Data Error]' message on your Omron Touch terminals indicates an error in the date/time values, possibly due to low battery voltage. Check the battery voltage by checking the color of the RUN LED and with the battery check in the System Menu; if the voltage is low, replace the battery with a new one. If the battery voltage is normal, set the calendar clock correctly from the System Menu.
