~ [!) Rdec [D ON ; m OFF SpeciIies whether or not to display
calculation resUiiSUSlng recurmg deanaliorm.
~ m Disp [D Dot; m Comma Specifies whether to display a dot or
a comma for the calculation result decimal point. A dot is always displayed
during input.
Note: When dot is selected as the decimal point, the separator for multiple
results is a comma (,). When comma is selected, the separator is a
semicolon (;).
~ !II CONT~ Adjusts display contrast. See "Adjusting Display
Contrast" for details.
Initializing Calculator Settings
Perform the foltowing procedure to initialize the calculator, which returns the
calculation mode to COMP and returns alt other settings, including setup
menu setlings, to their initial defaults.

Basic Input Rules
Calculations can be input in the same form as they are written, When you
press §) the pIioIity sequence of the input calculation will be evaluated
~ and the result will appear on the display.

Input of the closing parenthesis is required tor sin, sinh, and other functions
that includeparentheses. .
.,
These multiplication symbols (x) can be omitted. A multiplication symbol
can be omittedwhenitoccursimmediately beforean openingparenthesis,
immediately before sin or other function that includes parentheses,
immediatelybefore the Ran# (randomnumber)function,or immediately
before a variable(A,S, C, 0, E, F, M,X, Y),scientificconstants, 1tor e.
., The closing parenthesis immediatelybefore the §) operation can be
omitted.

Note:
.
It the calculation becomes longer than the screen width during
input, the screen willscroll automatically to the right and the indicator will
appear on the display. When this happens, you can semi back to the left by
using @ and <e) to move the cursor.
.
When LiIear Display is selected,
pressing @ willcause the cursor to jump to the ~ of the calculation,
while ~ will jump to the end.
.
When NaIuIaI Display is selected, pressing
E-7
<e) while the cursor is at the end of the input calculation will cause ~to jump
to the beginning, while pressing @ while the cursor is at the beginning will
cause it to jump to the end.
.
You can input up to 99 bytes for a calculation.
Each numeral, symbol, or function normally uses one byte. Some functions
require three to 13 bytes.
.
The cursor will change shape to . when there are
10 bytes or less of allowed input remaining. It this happens, end calculation
input and then press §).
Calculation Priority Sequence
The priority sequence of input calculations is evaluated in accordance w~h the
rules below. When the priority of two expressions is the same, the calculation
is performed trom left to right.
Inputting with Natural Display
Selecting Natural Display makes it possible to input and display fractions
and certain functions (log, XZ,XZ, x ', r., >r., 'ro, x-', 10', e',l, dJdx, I, II,
Abs) just
as they are writtenin yourtextbook.

Functions that require an argument to the right and a closing
parenthesis "j" following the argument.
3rd
Functionsthat
come after the input value
(r, x3,x-1,x!, 01.,°, " g,

4th Fractions
Negative sign H, base-n symbols (d, h, b, 0)
Note: When squaring a negative value (such as 2), the value
being squared must be enclosed in parentheses (IIJ IBJ 2 m
5th
§). Since XZhas a higher priority than the negative sign,
inputting IBJ 2 §) would result in the squaring of 2 and then
appending a negative sign to the result. Always keep the priority
sequence in mind, and enclose negative values in parentheses
when required.

Metric conversion commands (cmin, etc.),
