• An error occurs if parameters are not configured correctly.

Use the following function menus to maneuver between calculation result screens.

• { REPEAT } … {parameter input screen}

• { GRAPH } … {draws graph}

After drawing a graph, you can press

!1(TRACE) to turn on trace and read calculation

results along the graph.

Each press of

e while trace is turned on cycles the displayed value in the sequence: present

value (

PV

)

→ simple interest (

SI

)

→ simple future value (

SFV

). Pressing

d cycles in the

reverse direction.

Press

J to return to the parameter input screen.
