• 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.
