5. Handling Precautions
Dim figures on the display of the calculator indicate that battery
power is low. Continued use of the calculator when the battery
is low can result in improper operation. Replace the battery
as soon as possible when display figures becomes dim. Even
if the calculator is operating normally, replace the battery at
least once every two years (fx-82MS/82SX PLUS/220 PLUS), or
three years (fx-85MS/300MS/350MS). A dead battery can leak,
causing damage to and malfunction of the calculator. Never
leave a dead battery in the calculator.
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.
Never try to take the calculator apart.
Use a soft, dry cloth to clean the exterior of the calculator.
Whenever discarding the calculator or batteries, be sure to
do so in accordance with the laws and regulations in your
particular area.
