BASIC DEFINITIONS

The Keys

To keep your calculators 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.

OVERFLOW / ERROR CONDITIONS

A symbol “ E ” is indicated on the display when any of the following conditions occur and further calculation becomes impossible. Just press [ ON/C ] to release those overflow or error indicator and the subsequent calculation can then be performed.

• An intermediate or final calculation result exceed 1 x 10

(including memory calculations).

• You try to divide by zero.

• 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.)

• You try to store over 40 steps in a program.

To clear calculation after an overflow condition, press [ ON/C ].

POWER SUPPLY

To turn the calculator on, press [ ON/C ] ; To turn the calculator off, press [ OFF ]. This calculator automatically turns it off when not operated for approximately 9 minutes. It can be reactivated by pressing [ ON/C ] key and the display, memory, settings are retained.

The calculator is powered by two alkaline batteries (G13 or LR44). When the display dims, replace the batteries. Be careful not to be injured when you replace the battery.

1. Unscrew the 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 properly. 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.

any number previosly stored.

• To clear the memory’s contents, press [ 0 ] [ XÆM ] or [ ON/C ]

[ X

PROGRAMMING

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 word, 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 steps. It remembers the

-E13-

SRP-145N_English_Black_SR135A_090330.doc SIZE: 140x75mm

SCALE 2:1 2009/3/30

procedure even after you turn off the calculator. You can have more than one variable in your calculation.

Your calculator learns mathermatical procedures or programs in the program (PGM) mode. To set the calculator to the program mode, press [ 2ndF ] [ PGM ]. PGM appears on the display.

Now enter your procedure as if you were just going to calcualte it once

─except─press [ 2ndF ] [ [X] ] before entering variable data. You get

your first answer while you are still in the PGM mode. Note : If you press [ 2ndF ] [ [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 dispalys E. Press [ ON/C ] to clear the error.

To stop storing a program, press [ 2ndF ] [ 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 answers appears on the display.

Stored programs are automatically erased when you press [ 2ndF ] [ 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 calculation (in PGM mode), press [ = ] when you reach the point where you want the interim value displayed. Then press [ 2ndF ] [ HALT ] and continue entering your formula in the usual way.

When you run the program, press [ RUN ] after the calculator dispalys 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.

(Ex.) Find the total amount of principal and interest on a $5,000 loan

(x) at 6% annual interest (y) compounded annually over a period of 7 years (z) ?

z

Formula : total amount = x (1 +y ) (Ex.) : (1) x = $5,000 (2) x = $1,000

y = 6 % y = 10 % z = 7 years z = 5 years

SUMINISTRO DE ENERGIA

Para encender la máquina calculadora, presionar [ON/C]; para apagar la máquina calculadora, presionar [2ndF] [OFF]. Esta máquina calculadora se apaga automáticamente cuando no está operando aproximadamente durante 9-15 minutos. La energía puede ser restaurada presionando la tecla [ON/C] nuevamente. Contenidos memorizados & el previo modo puesto serán guardados.

La calculadora es alimentada por duas baterías alcalinas G13(LR44). Cuando la visualización se torna borrosa, sustituya las baterías. Tenga cuidado al reemplazar la batería para no ser herido.

1.

Soltar los tornillos en la parte trasera de la calculadora.
