## Technical Information

**Getting Started**

**Key Markings**

fx-82MS/fx-85MS/fx-300MS/fx-350MS: Pressing the or key followed by a second key performs the alternate function of the second key.

fx-220 PLUS: Pressing the key followed by a second key performs the alternate function of the second key.

The alternate function is indicated by the text printed above the key.

fx-82MS/fx-85MS/fx-300MS/fx-350MS:

(1) Keycap function (2) Alternate functionfx-220 PLUS:

The following shows what the different colors of the alternate function key text mean.

If key marking text is this color: |
It means this: |
---|---|

Yellow | Press and then the key to access the applicable function. |

Red | Press and then the key to input the applicable variable, constant, function, or symbol. (fx-82MS/fx-85MS/fx-300MS/fx-350MS only) |

Blue (or enclosed in blue brackets) | Enter the SD Mode and REG Mode to access the function. (fx-82MS/fx-85MS/fx-300MS/fx-350MS only) |

The following shows an example of how an alternate function operation is represented in this manual.

Example: (sin-1)* 1 * Indicates the function that is accessed by the key operation () before it. Note that this is not part of the actual key operation you perform.

The following shows an example of how a key operation to select an on-screen menu item is represented in this manual.

Example: (COMP)* * Indicates the menu item that is selected by the number key operation () before it. Note that this is not part of the actual key operation you perform.

The cursor key is marked with four arrows, indicating direction, as shown in the illustration nearby. In this manual, cursor key operation is indicated as , , , and .
