Use only the type of battery specified for this calculator in this manual. Handling Precautions Even if the calculator is operating no
10、rmally, replace the battery at least once every three years (LR44 (GPA76), two years (R03 (UM-4), or one year (LR03 (AM4). A dead battery can leak, causing damage to and malfunction of the calculator. Never leave a dead battery in the calculator. Do not try using the calculator while the battery is
11、completely dead (fx-85ES PLUS). The battery that comes with the calculator discharges slightly during shipment and storage. Because of this, it may require replacement sooner than the normal expected battery life. Do not use an oxyride battery* or any other type of nickel-based primary battery with
12、this product. Incompatibility between such batteries and product specifications can result in shorter battery life and product malfunction. Avoid use and storage of the calculator in areas subjected to temperature extremes, and large amounts of humidity and dust. E-3 Do not subject the calculator to
13、 excessive impact, pressure, or bending. Never try to take the calculator apart. Use a soft, dry cloth to clean the exterior of the calculator. Whenever discarding the calculator or batteries, be sure to do so in accordance with the laws and regulations in your particular area. * Company and product

Red Press and then the key to input the applicable variable, constant, or symbol. sin 1 D s Alternate function Keycap function sin 1 D s Alternate function
19、 Keycap functionE-4 Reading the Display The display of the calculator shows expressions you input, calculation results, and various indicators. Input expression Indicators Calculation result If a indicator appears on the right side of the calculation result, it means the displayed calculation result
20、 continues to the right. Use and to scroll the calculation result display. If a indicator appears on the right side of the input expression, it means the displayed calculation continues to the right. Use and to scroll the input expression display. Note that if you want to scroll the input expression
21、 while both the and indicators are displayed, you will need to press first and then use and to scroll. Display indicators This indicator: Means this: S The keypad has been shifted by pressing the key. The keypad will unshift and this indicator will disappear when you press a key. A The alpha input m
22、ode has been entered by pressing the key. The alpha input mode will be exited and this indicator will disappear when you press a key. M There is a value stored in independent memory. STO The calculator is standing by for input of a variable name to assign a value to the variable. This indicator appe
23、ars after you press (STO). RCL The calculator is standing by for input of a variable name to recall the variables value. This indicator appears after you press . STAT The calculator is in the STAT Mode. The default angle unit is degrees. The default angle unit is radians. The default angle unit is g
24、rads. FIX A fixed number of decimal places is in effect. SCI A fixed number of significant digits is in effect. Math Natural Display is selected as the display format. Calculation history memory data is available and can be replayed, or there is more data above/below the current screen. Disp The dis
25、play currently shows an intermediate result of a multi-statement calculation. Important: For some type of calculation that takes a long time to execute, the display may show only the above indicators (without any value) while it performs the calculation internally. Math Math Math MathE-5 Using Menus
26、 Some of the calculators operations are performed using menus. Pressing or , for example, will display a menu of applicable functions. The following are the operations you should use to navigate between menus. You can select a menu item by pressing the number key that corresponds to the number to it
27、s left on the menu screen. The indicator in the upper right corner of a menu means there is another menu below the current one. The indicator means another menu above. Use and to switch between menus. To close a menu without selecting anything, press . Specifying the Calculation Mode When you want t
28、o perform this type of operation: Perform this key operation: General calculations (COMP) Statistical and regression calculations (STAT) Equation solution (fx-95ES PLUS only) (EQN) Generation of a number table based on an expression fx-82/85/350ES PLUS: (TABLE) fx-95ES PLUS: (TABLE) Inequality solut
29、ion (fx-95ES PLUS only) (INEQ) Ratio calculations (fx-95ES PLUS only) (RATIO) Note: The initial default calculation mode is the COMP Mode. Configuring the Calculator Setup First perform the following key operation to display the setup menu: (SETUP). Next, use and and the number keys to configure the
30、 settings you want. Underlined ( _ ) settings are initial defaults. MthIO LineIO Specifies the display format. Natural Display (MthIO) causes fractions, irrational numbers, and other expressions to be displayed as they are written on paper. MthIO: Selects MathO or LineO. MathO displays input and cal
31、culation results using the same format as they are written on paper. LineO displays input the same way as MathO, but calculation results are displayed in linear format. Linear Display (LineIO) causes fractions and other expressions to be displayed in a single line. Note: The calculator switches to L
32、inear Display automatically whenever you enter the STAT Mode. In this manual, the symbol next to a sample operation indicates Natural Display (MathO), while the symbol indicates Linear Display. CE-6 Deg Rad Gra Specifies degrees, radians or grads as the angle unit for value input and calculation res
33、ult display. Note: In this manual, the symbol next to a sample operation indicates degrees, while the symbol indicates radians. Fix Sci Norm Specifies the number of digits for display of a calculation result. Fix: The value you specify (from 0 to 9) controls the number of decimal places for displaye
34、d calculation results. Calculation results are rounded off to the specified digit before being displayed. Example: 100 7 = 14.286 (Fix 3)14.29 (Fix 2) Sci: The value you specify (from 1 to 10) controls the number of significant digits for displayed calculation results. Calculation results are rounde
35、d off to the specified digit before being displayed. Example: 1 7 = 1.4286 10 1(Sci 5)1.429 10 1(Sci 4) Norm: Selecting one of the two available settings (Norm 1, Norm 2) determines the range in which results will be displayed in non-exponential format. Outside the specified range, results are displ
36、ayed using exponential format. Norm 1: 10 2 |x|, |x| 10 10Norm 2: 10 9 |x|, |x| 10 10 Example: 1 200 = 5 10 3(Norm 1)0.005 (Norm 2) ab/c d/c Specifies either mixed fraction (ab/c) or improper fraction (d/c) for display of fractions in calculation results. fx-95ES PLUS: CMPLX a+bi ; r Specifies eithe
37、r rectangular coordinates (a+bi) or polar coordinates (r ) for EQN Mode solutions. fx-82/85/350ES PLUS: STAT ON ; OFF fx-95ES PLUS: STAT ON ; OFF Specifies whether or not to display a FREQ (frequency) column in the STAT Mode Stat Editor. fx-82/85/350ES PLUS: Disp Dot ; Comma fx-95ES PLUS: Disp Dot ;
38、 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 (;). fx-82/8

When this happens, you can scroll back to the left by using and t
44、o move the cursor. When Linear Display is selected, pressing will cause the cursor to jump to the beginning of the calculation, while will jump to the end. When Natural Display is selected, pressing while the cursor is at the end of the input calculation will cause it to jump to the beginning, while
45、 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 allo
46、wed input remaining. If this happens, end calculation input and then press . Calculation Priority Sequence The priority sequence of input calculations is evaluated in accordance with the rules below. When the priority of two expressions is the same, the calculation is performed from left to right. 1
