Handling Precautions

  Your calculator is made up of precision components.  Never try to take
  it apart.

  Avoid dropping your calculator and subjecting it to other 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.

  The display will go blank and keys will not operate during calculations.
  When you are operating the keyboard, be sure to watch the display to
  make sure that all your key operations are being performed correctly.

  Replace batteries once every 2 years regardless of how much the
  calculator is used during this period.  Never leave dead batteries in
  the battery compartment.  They can leak and damage the unit.

  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
  dipped in a solution of water and a neutral detergent and wrung out.

  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.  The user
  should prepare physical records of data to protect against such data
  loss.

  Never dispose of batteries, the liquid crystal panel, or other
  compo nents by burning them.

  When the "Low battery" message appears on the display, replace the
  main power supply batteries as soon as possible.

  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 All Reset operation to clear the memory and restore
  normal key operation.

  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 manual and ensure that the problem is not due to insufficient
  battery power, programming or operational errors.
