HANDLING PRECAUTIONS

• Be sure to press the RESET button on the back of the calculator before using it for the first time.
• Even if the calculator is operating normally, replace the battery at least once every three years. Dead battery can leak, causing damage to and malfunction of the calculator. Never leave the dead battery in the calculator.
• The battery that comes with this unit discharges slightly during shipment and storage. Because of this, it may require replacement sooner than the normal expected battery life.
• 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. Also avoid leaving the calculator in direct sunlight, near a window, near a heater or anywhere else it might become exposed to very high temperatures. Heat can cause discoloration or deformation of the calculator's case, and damage to internal circuitry.

• Avoid use and storage in areas subjected to large amounts of humidity and dust. Take care never to leave the calculator where it might be splashed by water or exposed to large amounts of humidity or dust. Such elements can damage internal circuitry.

• Never drop the calculator or subject it to strong impact.

• Never twist or bend the calculator. Avoid carrying the calculator in the pocket of your trousers or other tight-fighting clothing where it might be subjected to twisting or bending.
• Never try to take the calculator apart.
• Never press the keys of the calculator with a ballpoint pen or other pointed object.
• Use a soft, dry cloth to clean the exterior of the unit. If the calculator becomes very dirty, wipe it off with a cloth moistened in a weak solution of water and a milk neutral household detergent. Remove all excess moisture before wiping the calculator. Never use thinner, benzine or other volatile agents to clean the calculator. Doing so can remove printed markings and damage the case.
