Handling Precautions

Be sure to press the 5 key before using the calcu- lator for the first time.

Even if the calculator is operating normally, replace the battery at least once every three years for the fx- 83MS/fx-85MS/fx-270MS/fx-300MS/fx-350MS, or at least once every two years for the fx-82MS.

A dead battery can leak, causing damage to and mal- function of the calculator. Never leave a 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 tem- perature 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 be exposed to very high temperatures. Heat can cause dis- coloration 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 conditions can damage internal circuitry.
