uGraphs
As a general rule, graph operations are shown on
facing pages, with actual graph examples on the right
hand page. You can produce the same graph on your
calculator by performing the steps under the Procedure
above the graph.
Look for the type of graph you want on the right hand
page, and then go to the page indicated for that graph.
The steps under “Procedure” always use initial RESET
settings.
The step numbers in the “Set Up” and “Execution” sections on the left hand page
correspond to the “Procedure” step numbers on the right hand page.
Example:
Left hand page Right hand page

uCommand List
The PRGM Mode Command List (page 8-7) provides a graphic flowchart of the various
function key menus and shows how to maneuver to the menu of commands you need.

kAbout the Function Menu
Use the function keys (1 to 6) to access the menus and commands in the menu bar
along the bottom of the display screen. You can tell whether a menu bar item is a menu or a
command by its appearance.
• Next Menu
Example:
Selecting displays a menu of hyperbolic functions.
• Command Input
Example:
Selecting inputs the sinh command.
• Direct Command Execution
Example:
Selecting executes the DRAW command.

kAbout Display Screens
This calculator uses two types of display screens: a text screen and a graph screen. The text
screen can show 21 columns and 8 lines of characters, with the bottom line used for the
function key menu. The graph screen uses an area that measures 127 (W) ⋅ 63 (H) dots.
Text Screen Graph Screen
The contents of each type of screen are stored in independent memory areas.
Press !6(GT) to switch between the graph screen and text screen.
