    • 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.
  • Page 11: Kinput Capacity

    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.
  • Page 12: Kexponential Display Formats

    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).

    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.
  • Page 29: Korder Of Operations

    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.
  • Page 30: Kpower Supply

    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.
  • Page 31: Replacing The Battery

    < 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.
