Avoid use and storage in areas subjected to large amounts of humidity and dust. Take care never to leave the calculator where it might be splashed by water or exposed to large amounts of hu- midity or dust. Such elements can damage internal cir- cuitry.
• You cannot set the angle unit or the display mode while the calculator is in the BASE-N mode (fx-85W). • The COMP, SD, and REG modes can be used in combi- nation with the angle unit modes.
k Input Capacity • The memory area used for calculation input can hold 79 “steps.” Whenever you input the 73rd step of any calcu- lation, the cursor changes from “_” to “k” to let you know memory is running low. If you still need to input more, you should divide your calculation into two or more parts.
Exponential Display Formats This calculator can display up to 10 digits. Larger values are automatically displayed using exponential notation. In the case of decimal values, you can select between two formats that determine at what point exponential notation is used. Press NORM 1 or NORM 2 (fx-85W).
Basic Calculations • Use the COMP mode for basic calculations. • Example 1 : 3 (5 10 • Example 2 : 5 (9 7) • You can skip all Memory Calculations k Independent Memory • Values can be input directly into memory, added to memor y, or subtracted from memory.
• Example: 193.2 Ö 23 193.2 Ö 28 193.2 Fraction Calculations k Fraction Calculations • Use the COMP mode for fraction calculations. • Values are automatically displayed in decimal format whenever the total number of digits of a fractional value (integer numerator exceeds 10.
Percentage Calculations • Use the COMP mode for percentage calculations. • Example 1 : To calculate 12% of 1500 • Example 2 : To calculate what percentage of 880 is 660 • Example 3 : To add 15% onto 2500 2500 •...

• You can use the following logical operators between values in Base- (logical sum), xor (exclusive logical sum), xnor (exclu- sive logical sum negation), Not (negation), and Neg (minus). • The following are the allowable ranges for each of the available number systems.
< fx-350TL> If the above steps do not correct your problem, press the P button (see page 29) on the back of the calculator to reset it. Pressing the P button deletes all data stored in calculator memory. Make sure you always keep written copies of all important data.
Make sure you always keep written copies of all important data. k Error Messages The calculator is locked up while an error message is on the display. Press to display the calculation and correct the problem. See “Error Locator” on page 9 for details.
Other operations are performed from left to right. * Operations enclosed in parentheses are performed first. k Stacks This calculator uses memory areas, called “stacks,” to tem- porarily store values (numeric stack) and commands (com- mand stack) according to their precedence during calcu- lations.
Normally, calculators equipped with a solar cell alone can operate only when relatively bright light is present. The TWO WAY POWER system, however, lets you con- tinue to use the calculator as long as there is enough light to read the display. • Replacing the Battery Either of the following symptoms indicates battery power is low, and that the battery should be replaced.
< fx-350TL> This calculator is powered by single G13 Type (LR44) but- ton battery. • Replacing the Battery Dim figures on the display of the calculator indicate that battery power is low. Continued use of the calculator when the battery is low can result in improper operation.
