Page 4: Safety Information
LCD−8310 Scientific Calculator Safety Information It is essential to read the following safety information before starting to use the calculator. Keep this guide close to hand for reference later. Intended Use This calculator serves exclusively for completing arithmetical processes indoors. Any other use is considered unintended use. Batteries After removing the batteries from the calculator, put them in a safe place where there is no danger of them getting into the hands of... - Page 5 Low battery power can cause memory contents to become corrupted or lost completely. Always keep written records of all important data. Avoid use and storage in areas subjected to temperature extremes. Very low temperatures can cause slow display response, total failure of the display, and shortening of battery life.
