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. - 2 - • 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.

B. O,or B twice after inputting a number to make that number a constant. • “K” is on the display while a constant is being used. • Use the COMP mode for constant calculations. • Example 1: 2.3+3, then 2.3+6 (2.3+3) 2.3 O O 3 B CO 10 * (2.3+6) 6 B I co CO * • Example 2: 12x2.3, then 12x(-9) (12x2.3) 12 O O 2.3 B I K 27.6 | (12x(-9)) 9 E B | K -108. | • Example 3: 17 + 17+17 + 17=68 (17+17) 17 O O B K 34.

Y replaces current memory contents. • “M” appears when there is a value in memory. • To clear memory, press IO Y or T Y. • Example 1 ck C* T X CD J-0 T co 1 CO T CD + CO -4)= 5 .7 O c\l (53+6) 53 □ 6 B Y I M 59. | (23-8) 23 B 8 E 1 M 15.
