Handling Precautions

•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 temperature, 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.

•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 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 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 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 low battery power or 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.

•Keep this manual on hand for future reference.

Modes

*Display indicators show current mode setting. Absence of display indicator indicates COMP Mode.

The Calculator Came With A Basic Guide

With the purchase of these products is usually included a basic paper guide, this is not only insufficient (for lack of information) but also impractical, especially when making a new query and not have at hand the physical guide. For this reason, we believe it is necessary to offer you a backup in digital format so that you can access it whenever you need it.

You Have Lost The User Guide

You may also lose the instruction manual that came in the box. Therefore, the safest thing to do is to download the guide that you will find at the end of this article.
