Handling Precautions

• Be sure to press the 5 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.

• The above table is printed on the back of the calculator.

Note!

• A mode guide is located at the top of the display screen.

• DEG, RAD, and GRA modes can be used in combination

with COMP and SD modes.

•

F9 does not exit SD mode.

•

F0 exits SD mode.

•

F0 does not clear SCI or FIX specifications.

• Always press

t before entering DEG, RAD, and GRA

modes.

• Remember to always set the operating mode and angular

unit (DEG, RAD, GRA) before starting your calculation.
