Safety Precautions

Battery

• Keep batteries out of the reach of small children.

• Use only the type of battery specified for this calculator in this manual.

Handling Precautions

• Even if the calculator is operating normally, replace the battery at least

once every three years (LR44 (GPA76)) or two years (R03 (UM-4)).

A dead battery can leak, causing damage to and malfunction of the

calculator. Never leave a dead battery in the calculator. Do not try using

the calculator while the battery is completely dead (fx-991ES PLUS).

• The battery that comes with the calculator discharges slightly during

shipment and storage. Because of this, it may require replacement

sooner than the normal expected battery life.

• Do not use an oxyride battery* or any other type of nickel-based

primary battery with this product. Incompatibility between such

batteries and product specifications can result in shorter battery life

and product malfunction.

• Avoid use and storage of the calculator in areas subjected to

temperature extremes, and large amounts of humidity and dust.

• Do not subject the calculator to excessive impact, pressure, or

bending.
