• Note that the EQUA and TVM items appear for function keys ( and ) only when you
access the variable data menu from the RUN • MAT (or RUN) or PRGM mode.
• The variable data menu does not appear if you press ) while binary, octal, decimal, or
hexadecimal is set as the default number system.
• Depending on the calculator model, some menu items may not be included.
• For details about the commands included on the variable data (VARS) menu, see the “)

The dot value indicates the display range (Xmax value – Xmin value) divided by the
screen dot pitch (126). The dot value is normally calculated automatically from the
minimum and maximum values. Changing the dot value causes the maximum to be
calculated automatically.
