BASIC DEFINITIONS

The Keys

To keep your calculator as compact as possible, some keys have more than one function. You can change the function of a key by pressing another key first, or by setting the calculator in a certain mode. The following pages give you more detailed explanation of each key's use and function.
[SHIFT] Second Function Select Key Some keys have a second function inscribed above them (for example, 1/x is above x2). To perform this second function, press [SHIFT]. "2F" appears in the display. Then press the key. Example: To calculate the reciprocal of 5, press [5] [SHIFT] [1/x]. The display shows 0.2. In this manual, we refer to the key by the desired function. So, the example would be shown as [5] [SHIFT] [1/x].

General Keys

[0] - [9] [ ] Data Entry Keys Press these keys in their logical sequence to enter numbers. [+], [], [x], [ ], [=] Basic Calculation Keys Press these keys in their logical sequence for addition, subtraction, multiplication, division, and to display answers. [ON/C] Power ON/Clear Key Press [ON/C] to turn on the calculator and to clear everything except the contents of the memory, constant memory (Ka, Kb), and program memory. It also overrides the auto power-off function. [CE] Clear Entry Key Press [CE] to erase incorrect entries. [+/] Sign Change Key Press [+/] to change the displayed number from positive to negative or from negative to positive. If you press [+/] after pressing [EXP], the sign of the exponent changes.

Memory Keys

[MR] Memory Recall Key Press [MR] to display the contents of the memory. [X M] Memory Store Key Press [X M] to store the displayed value into memory. Any previous value in memory is automatically erased. [M+] Memory Plus Key Press [M+] to total the current calculation and add the result to the value already in memory. -E2-
[SHIFT] [Kax k], [SHIFT] [Kbx k] Constant (Ka, Kb) Memory Store Key Press to enter the displayed value into constant memory Ka or Kb. [Kax k], [Kbx k] Constant (Ka, Kb) Memory Recall Key Press to display the contents of a constant memory. Notes: Constant memories Ka and Kb can have a value of 0. If you press [Kax k] or [Kbx k] after entering a number or making a calculation, the displayed value is multiplied by the value in Ka or Kb.

Special Keys

[ ( ], [ ) ] Parenthesis Keys This calculator uses true algebraic logic. It performs calculations using the following priority: 1) Functions 2) Calculations in parenthesis 3) Power and root calculations 4) Multiplication and division 5) Addition and subtraction To change this order, enclose the expressions that must be calculated first within [ ( ] and [ ) ]. In a single expression, you can use a maximum of 42 nested parentheses at 6 levels (nesting of up to 7 parentheses in one level). For example, if you press [] 6 [x2] [=], the calculator gives a result of 36. This might seem incorrect at first, since the square of a negative number is always positive. However, if you refer to the above priority sequence, you see that the power ([x2]) has a higher priority than the minus ([]). So the calculator sees the entry as the negative of six squared. To make the calculator perform negative six, squared enter [ ( ] [] 6 [ ) ] [x2] [=]. This forces the calculator to resolve the [] 6 and then square the result. [EXP] Exponent Key To enter a number in scientific notation, first enter the numbers for the mantissa, press [EXP], and then enter the numbers for the exponent. [SHIFT] [ ] Key Press [SHIFT] [ ] to display the value of , which is the ratio of a circles circumference to its diameter (approximately 3.141592654). [SHIFT] [ o ], [SHIFT] [o ] Sexagesimal notation/decimal notation conversion Keys To change from sexagesimal (base 60) notation (degree, minute, second) to decimal notation (degree) press [SHIFT] [o ]. To change from decimal notation to sexagesimal notation, enter the number in decimal form and then press [SHIFT] [ o ]. -E3-

[SHIFT] [XY] Register Exchange Key Press [SHIFT] [XY] to exchange the displayed value (Xregister) with the contents of the working register (Yregister). [SHIFT] [FIX] Decimal Point Set Key Use to set the number of digits displayed after the decimal point in either final or intermediate results. The calculator continues to use its full range for internal calculations, and only rounds the number in the display. [SHIFT] [FIX] [0] - [6] Sets the number of digits to be displayed to the right of decimal point. [SHIFT] [FIX] [7], [8], [9], [ ] Selects floating point format. Note: [SHIFT] [FIX] is inactive immediately after and during numerical input. [DRG] Pressing this key will change the mode of angle unit DEG RAD GRAD and display it on LCD. sequentially [OFF] Power off key

The number in brackets shows the number of the place of the variable, and goes from 1 - 40.

OVERFLOW OR ERROR CHECK

An overflow or error is indicated by "E". Stop further calculations. An overflow or error occurs when: a) An intermediate or final calculation result exceeds 1 x 10100 (including memory calculations). b) You try to divide by zero. c) The number of low priority storage levels exceeds 6 in a parentheses calculation or nesting parentheses exceed 7 in one level. (Even if the number of levels is within 6, an error might occur if you are using memories Ka or Kb, or program memories.) d) You try to use [SHIFT] [KaX K] or [SHIFT] [KbX K] while memories Ka and Kb are being used for low-priority calculation storage. e) You make a calculation that is out of the range for functional and statistical calculations. f) You try to store over 40 steps in a program. To clear calculations after an overflow condition, press [ON/C]. Memory Protection: Memory contents are protected against overflow or error conditions. If a memory operation would result in the memory value exceeding 1 x 10100, the calculator displays E and does not change the value in memory.

REPLACING THE BATTERIES

Your calculator is powered by two alkaline-manganese batteries. When the display dims, replace the batteries. 1. Unscrew the two screws on the back of the calculator. 2. Insert a flat bladed screwdriver into the slot between the upper and lower case then carefully twist it to separate the case. 3. Remove both batteries and dispose of them promptly. Never allow children to play with batteries. 4. Wipe off the new batteries with a dry cloth to maintain good contact. 5. Insert the two new batteries with their flat sides (plus terminals) up. 6. Align the upper and lower cases then snap them to close together. -E7-

7. Tighten the screws.

BASIC OPERATION
TURNING ON THE CALCULATOR
Press [ON/C] to turn on your calculator. A " 0 " shows on the display. If you leave your calculator on without making any calculation, it automatically turns itself off in approximately 10 minutes to save battery life. Note: Even when the power is off, the calculators memory retains the contents of the independent memory, constant memory registers, and any program steps.

Normal Calculations

The calculator operates using true algebraic logic; calculations can be performed in the same sequence as the written formula. You can nest up to 42 parentheses at 6 levels, with up to 7 parentheses in one level.

PROGRAMMING

Storing Mathematical Procedures
With your Programmable Scientific Calculator, complex repeated calculations are no longer time-consuming chores. All you have to do is tell the calculator what you want to do in a way it can understand (in other words, program it). Your calculator can store one procedure with up to 40 steps. These "steps" can be either steps (like mathematical functions) or characters (like numbers). Each function counts as one step. It remembers the procedure even after you turn off the calculator. You can have more than one variable in your calculation. -E19-
Your calculator learns mathematical procedures or programs in the Program (PGM) Mode. To set the calculator to the Program Mode, press [SHIFT] [PGM]. PGM appears on the display. Now enter your procedure as if you were just going to calculate it once - except - press [SHIFT] [[x]] before entering variable data. You get your first answer while you are still in the PGM mode.
Note: If you press [SHIFT] [[x]] then [ ] or a number, and then [EXP], [+/], [ ) ] or [CE], both the number and the first function following the number are treated as one variable - they are not written into the program as steps.
Remember, you can enter a maximum of 40 steps. If you try to enter a 41st step, the calculator displays E. Press [ON/C] to clear the error. To stop storing a program, press [SHIFT] [PGM] again. PGM disappears and the calculator leaves the program mode. Press [RUN] to begin repeating the same mathematical procedure with different variables. When you press [RUN], you can begin entering different variables. Just enter each variable in the order in which it occurs in the formula and press [RUN] after each variable. The answer appears on the display. Stored programs are automatically erased when you press [SHIFT] [PGM]. So, unless you want to enter a new program, do not select the program mode. You can program your calculator to give you interim values in your formula also. While programming the calculator (in PGM mode), press [=] when you reach the point where you want the interim value displayed. Then press [SHIFT] [HALT] and continue entering your formula in the usual way. When you run the program, press [RUN] after the calculator displays an interim value to resume the program. You can use the same method to program your calculator to run two or more formulas, one after another.

BASIC DEFINITIONS

The Keys
To keep your calculator as compact as possible, some keys have more than one function. You can change the function of a key by pressing another key first, or by setting the calculator in a certain mode. The following pages give you more detailed explanation of each key's use and function. 2ndF
[SHIFT] Second Function Select Key
Some keys have a second function inscribed above them (for example, 1/x is above x 2). To perform this second function, press [SHIFT]. "2F" appears in the display. Then press the key. Example: To calculate the reciprocal of 5, press [5] [SHIFT] [1/x]. The display shows 0.2. In this manual, we refer to the key by the desired function. So, the example would be shown as [5] [SHIFT] [1/x].

General Keys

[0] - [9] [ ] Data Entry Keys Press these keys in their logical sequence to enter numbers. [+], [], [x], [], [=] Basic Calculation Keys Press these keys in their logical sequence for addition, subtraction, multiplication, division, and to display answers. [ON/C] Power ON/Clear Key Press [ON/C] to turn on the calculator and to clear everything except the contents of the memory, constant memory (Ka, Kb), and program memory. It also overrides the auto power-off function. [CE] Clear Entry Key Press [CE] to erase incorrect entries. [+/] Sign Change Key Press [+/] to change the displayed number from positive to negative or from negative to positive. If you press [+/] after pressing [EXP], the sign of the exponent changes.

Memory Keys

[MR] Memory Recall Key Press [MR] to display the contents of the memory. [X M] Memory Store Key Press [X M] to store the displayed value into memory. Any previous value in memory is automatically erased. [M+] Memory Plus Key Press [M+] to total the current calculation and add the result to the value already in memory. [SHIFT] [Kax k], [SHIFT] [Kbx k] Constant (Ka,Kb) Memory Store Key Press to enter the displayed value into constant memory Ka or Kb. [Kax k], [Kbx k] Constant (Ka, Kb) Memory Recall Key Press to display the contents of a constant memory. Notes: Constant memories Ka and Kb can have a value of 0. If you press [Kax k] or [Kbx k] after entering a number or making a calculation, the displayed value is multiplied by the value in Ka or Kb.

Special Keys

[ ( ], [ ) ] Parenthesis Keys This calculator uses true algebraic logic. It performs calculations using the following priority: 1) 2) 3) 4) 5) Functions Calculations in parenthesis Power and root calculations Multiplication and division Addition and subtraction
To change this order, enclose the expressions that must be calculated first within [ ( ] and [ ) ]. In a single expression, you can use a maximum of 42 nested parentheses at 6 levels (nesting of up to 7 parentheses in one level).
For example, if you press [] 6 [x2] [=], the calculator gives a result of 36. This might seem incorrect at first, since the square of a negative number is always positive. However, if you refer to the above priority sequence, you see that the power ([x2]) has a higher priority than the minus ([]). So the calculator sees the entry as the negative of six squared. To make the calculator perform negative six, squared enter [(] [] 6 [)] [x2] [=]. This forces the calculator to resolve the [] 6 and then square the result. [EXP] Exponent Key To enter a number in scientific notation, first enter the numbers for the mantissa, press [EXP], and then enter the numbers for the exponent. [SHIFT] [] Key Press [SHIFT] [] to display the value of , which is the ratio of a circles circumference to its diameter (approximately 3.141592654). [SHIFT] [ o ], [SHIFT] [o ] Sexagesimal notation/decimal notation conversion Keys To change from sexagesimal (base 60) notation (degree, minute, second) to decimal notation (degree) press [SHIFT] [ o ]. To change from decimal notation to sexagesimal notation, enter the number in decimal form and then press [SHIFT] [ o ]. [SHIFT] [XY] Register Exchange Key Press [SHIFT] [XY] to exchange the displayed value (Xregister) with the contents of the working register (Yregister). [SHIFT] [FIX] Decimal Point Set Key Use to set the number of digits displayed after the decimal point in either final or intermediate results. The calculator continues to use its full range for internal calculations, and only rounds the number in the display. [SHIFT] [FIX] [0] - [6] Sets the number of digits to be displayed to the right of decimal point. [SHIFT] [FIX] [7], [8], [9], [ ] Selects floating point format. Note: [SHIFT] [FIX] is inactive immediately after and during numerical input. [DRG] Pressing this key will change the mode of angle unit sequentially DEG RAD GRAD and display it on LCD.

The number in brackets shows the number of the place of the variable, and goes from 1 - 40.

OVERFLOW OR ERROR CHECK

An overflow or error is indicated by "E". Stop further calculations. An overflow or error occurs when: a) An intermediate or final calculation result exceeds 1 x 10100 (including memory calculations). b) You try to divide by zero. c) The number of low priority storage levels exceeds 6 in a parentheses calculation or nesting parentheses exceed 7 in one level. (Even if the number of levels is within 6, an error might occur if you are using memories Ka or Kb, or program memories.) d) You try to use [SHIFT] [KaX K] or [SHIFT] [KbX K] while memories Ka and Kb are being used for low-priority calculation storage. e) You make a calculation that is out of the range for functional and statistical calculations. f) You try to store over 40 steps in a program. To clear calculations after an overflow condition, press [ON/C]. Memory Protection: Memory contents are protected against overflow or error conditions. If a memory operation would result in the memory value exceeding 1 x 10100, the calculator displays E and does not change the value in memory. REPLACING THE BATTERIES Your calculator is powered by two alkaline-manganese batteries. When the display dims, replace the batteries. 1. Unscrew the two screws on the back of the calculator. 2. Insert a flat bladed screwdriver into the slot between the upper and lower case then carefully twist it to separate the case. 3. Remove both batteries and dispose of them promptly. Never allow children to play with batteries. 4. Wipe off the new batteries with a dry cloth to maintain good contact. 5. Insert the two new batteries with their flat sides (plus terminals) up. 6. Align the upper and lower cases then snap them to close together. 7. Tighten the screws.

BASIC OPERATION

TURNING ON THE CALCULATOR
Press [ON/C] to turn on your calculator. A " 0 " shows on the display. If you leave your calculator on without making any calculation, it automatically turns itself off in approximately 10 minutes to save battery life. Note: Even when the power is off, the calculators memory retains the contents of the independent memory, constant memory registers, and any program steps.

Normal Calculations

The calculator operates using true algebraic logic; calculations can be performed in the same sequence as the written formula. You can nest up to 42 parentheses at 6 levels, with up to 7 parentheses in one level.

Memory Calculations

Notes: Do not set the function mode to "SD" when performing memory calculations. A new number entered into memory by pressing [X M] replaces any number previously stored. To clear the memorys contents, press [0] [X M] or [ON/C] [X M] in sequence. M appears when a number beside "0" is stored in memory. When you press [SHIFT] [X M] after pressing [MR], the displayed number is exchanged with the contents of the memory. Example: 7 + 77 + (2x3)+(2x3)+(2x3)(2x3) = 19 Press [7] [X M] M [M+] M [+/] M [M+] M [2] M [x] M [3] M [M+] M [M+] M Display DEG 7. DEG 7. DEG 7. DEG 7. DEG 7. DEG 2. DEG 2. DEG 3. DEG 6. DEG 6.

PROGRAMMING

Storing Mathematical Procedures
With your Programmable Scientific Calculator, complex repeated calculations are no longer time-consuming chores. All you have to do is tell the calculator what you want to do in a way it can understand (in other words, program it). Your calculator can store one procedure with up to 40 steps. These "steps" can be either steps (like mathematical functions) or characters (like numbers). Each function counts as one step. It remembers the procedure even after you turn off the calculator. You can have more than one variable in your calculation. Your calculator learns mathematical procedures or programs in the Program (PGM) Mode. To set the calculator to the Program Mode, press [SHIFT] [PGM]. PGM appears on the display. Now enter your procedure as if you were just going to calculate it once - except - press [SHIFT] [[x]] before entering variable data. You get your first answer while you are still in the PGM mode. Note: If you press [SHIFT] [[x]] then [] or a number, and then [EXP], [+/], [)] or [CE], both the number and the first function following the number are treated as one variable - they are not written into the program as steps. Remember, you can enter a maximum of 40 steps. If you try to enter a 41st step, the calculator displays E. Press [ON/C] to clear the error. To stop storing a program, press [SHIFT] [PGM] again. PGM disappears and the calculator leaves the program mode. Press [RUN] to begin repeating the same mathematical procedure with different variables. When you press [RUN], you can begin entering different variables. Just enter each variable in the order in which it occurs in the formula and press [RUN] after each variable. The answer appears on the display.

Stored programs are automatically erased when you press [SHIFT] [PGM]. So, unless you want to enter a new program, do not select the program mode. You can program your calculator to give you interim values in your formula also. While programming the calculator (in PGM mode), press [=] when you reach the point where you want the interim value displayed. Then press [SHIFT] [HALT] and continue entering your formula in the usual way. When you run the program, press [RUN] after the calculator displays an interim value to resume the program. You can use the same method to program your calculator to run two or more formulas, one after another.
