• 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.

Memory Calculations
• Use the COMP mode for memory calculations. • Use Y, |, A { and Z for memory calculations.
Y replaces current memory contents.
• “M” appears when there is a value in memory. • To clear memory, press 0 Y or t Y.
• 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.
