Before using the
calculator
Handling Precautions
· 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.
· Avoid use and storage in areas subject to ex-
treme temperatures. 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 tempera-
tures. Heat can cause discoloration or deforma-
tion of the calculator's case, and damage to its
internal circuitry.
