Handling Precautions - Casio fx-FD10 Pro User Manual

2. Handling Precautions

• Your calculator is made up of precision components. Never try to take it apart.
• Avoid dropping your calculator and subjecting it to strong impact.
• Do not store the calculator or leave it in areas exposed to high temperatures or humidity, or
large amounts of dust. When exposed to low temperatures, the calculator may require more
time to display results and may even fail to operate. Correct operation will resume once the
calculator is brought back to normal temperature.
• Your calculator supports use of both alkaline batteries and rechargeable nickel-metal hydride
batteries. Note that the amount of operation between charges provided by nickel-metal
hydride batteries is shorter than the life of alkaline batteries. Use only batteries that are
specifically recommended for this calculator.
• Replace the main batteries once every one year regardless of how much the calculator
is used during that period. Never leave dead batteries in the battery compartment. They
can leak and damage the unit. Immediately remove nickel-metal hydride batteries from the
calculator after their charge is used up. Leaving uncharged nickel-metal hydride batteries in
the calculator can cause them to deteriorate.
• Keep batteries out of the reach of small children. If swallowed, consult a physician
immediately.
• Avoid using volatile liquids such as thinner or benzine to clean the unit. Wipe it with a soft,
dry cloth, or with a cloth that has been moistened with a solution of water and a neutral
detergent and wrung out.
• Always be gentle when wiping dust off the display to avoid scratching it.
• In no event will the manufacturer and its suppliers be liable to you or any other person for
any damages, expenses, lost profits, lost savings or any other damages arising out of loss
of data and/or formulas arising out of malfunction, repairs, or battery replacement. It is up to
you to prepare physical records of data to protect against such data loss.
• Never dispose of batteries, the liquid crystal panel, or other components by burning them.
• Be sure that the power switch is set to OFF when replacing batteries.
• If the calculator is exposed to a strong electrostatic charge, its memory contents may be
damaged or the keys may stop working. In such a case, perform the Reset operation to clear
the memory and restore normal key operation.
• If the calculator stops operating correctly for some reason, use a thin, pointed object to press
the RESTART button on the back of the calculator. Note, however, that this clears all the
data in calculator memory.
• Note that strong vibration or impact during program execution can cause execution to stop or
can damage the calculator's memory contents.
• Using the calculator near a television or radio can cause interference with TV or radio
reception.
• Before assuming malfunction of the unit, be sure to carefully reread this User's Guide and
ensure that the problem is not due to insufficient battery power, programming or operational
errors.
• Avoid contact with water and other liquids.
Though your calculator is designed to be splash-resistant, note that splash-resistance is
reduced if it is exposed to moisture, dirt, or dust while the battery compartment cover, USB
port cap, SD card cap, or other opening is uncovered. Moisture getting into the calculator
creates the risk of malfunction, fire, and electric shock.
