u To perform a binary, octal, decimal, or hexadecimal calculation
[SET UP] - [Mode] - [Dec]/[Hex]/[Bin]/[Oct]
1. In the Main Menu, select Run-Matrix .
2. Press !m(SET UP). Move the highlighting to “Mode”, and then specify the default

3. Press J to change to the screen for calculation input. This causes a function menu with
the following items to appear.
• { d~o } / { LOGIC } / { DISPLAY } ... {number system specification}/{bitwise operation}/
{decimal/hexadecimal/binary/octal conversion} menu
u To specify a number system for an input value
You can specify a number system for each individual value you input. Press 1(d~o) to display
a menu of number system symbols. Press the function key that corresponds to the symbol you
want to select and then input the value.
• { d } / { h } / { b } / { o } ... {decimal}/{hexadecimal}/{binary}/{octal}

!m(SET UP)
Move the highlighting to “Mode”, and then
press 3(Hex) J.
