Handling Precautions
5
• Be sure to press the key before using the calculator.
• Your calculator is made up of precision components.
Never try to take it apart.
• Avoid dropping your calculator and otherwise subjecting it
to strong impact.
• Do not store the calculator or leave it in areas exposed to
high temperature 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.
• With certain calculations, it may take some time before the
result is displayed. The display is blank while a calculation
is in progress.
• Avoid using volatile liquids such as thinner or benzine to
clean the unit. Wipe it with a soft cloth, or with a cloth
that has been dipped in a solution of water and a neutral
detergent and wring 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 malfunction, repairs, or insufficient light. The user
should prepare physical records of data to protect against
such data loss.
• Never dispose of the liquid crystal panel, or other
components by burning them.
• Before assuming malfunction of the unit, be sure to
carefully reread this manual and ensure that the problem
is not due to operational error.
• The contents of this manual are subject to change without
notice.
• No part of this manual may be reproduced in any form
without the express written consent of the manufacturer.
• Be sure to keep all user documentation handy for future
reference.
