Handling Precautions

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

once every three years (LR44 (GPA76)).

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.

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.
