Important!
Before you do anything, be sure to note the following important precautions!
Do not locate the cash register where it will be
subjected to direct sunlight, high humidity,
splashing with water or other liquids, or high
temperature (such as near a heater).
Never operate the cash register while your
hands are wet.
Never try to open the cash register or attempt
your own repairs. Take the cash register to your
authorized CASIO dealer for repairs.
Be sure to check the sticker on the side of the
cash register to make sure that its voltage
matches that of the power supply in the area.
Use a soft, dry cloth to clean the exterior of the
cash register. Never use benzene, thinner, or
any other volatile agent.
