Some of these features are 3 storage registers - There is no need to write down intermediate results or commonly used constants, such numbers can be stored in one of these registers, and recalled at any time when needed. Automatic decimal alignment - The decimal point is entered place where it occurs in the number. at the The number is positioned automatically. And so are all answers. Full display of registers - The contents of all registers are displayed. Proof of the number just entered is visible and you don't have to remember where you stored a number or what the number was. Correction capability - If any digit of a 24-digit number is entered incorrectly, you can pick out that digit and correct it. And there are a great many more features, explained in this manual, that make the Wyle SCIENTIFIC the most flexible and powerful calculator you can use. In spite of this unusual capability, the operation of the Wyle SCIENTIFIC is easy to learn. Operation is straightforward and requires no complex routines or techniques, even for relatively complex operations. The basic op- erations can be mastered in minutes. The purpose of this book is to acquaint you with the basic operations of the Wyle SCIENTIFIC 0 Each key, each function, and each section of the display is explained in full. These examples demonstrate the possible appl ications and others will become apparent as you use the machine in day-to-day operations. All keys and registers are explained in detail in the following pages; however, a general explanation of the keyboard and display will acquaint you with what to look for when operating the SCIENTIFIC and will explain some terms that will be used in the following pages. Documenent Scan Courtesy The Old Calculator Museum http://oldcalculatormuseum.com Display The top line of the display is the Multiplier-Quotient Register, abbreviated MQ. This register is used to hold the mul tipl ier in mul tipl ication operations, the quotient MQ Register in division operations, and the answer in Square Root Entry Register ACC. Register operati ons. Storage Reg. 1 Storage Reg. 2 The Entry Register holds the mul tipl icahd in mul tipl ica,- Storage Reg. 3 tion operations, the divisor in division operations, and the minuend in subtraction operations. It is the normal Wyle SCIENTIFIC Visual Display register for data entry and its contents are added to the contents of the Accumulator in the normal addition oper_ ation. The Accumulator Register, abbreviated ACC 0, is used to hold the original number (radicand) in Square Root operations, the dividend in division operation, and the subtrahend in subtraction operations. The answers to all addition, subtraction, and multipi ication operations of all types appear in this register 0 The three storage registers are numbered 1, 2 and 3 from top to bottom. Numben can be transferred to any of these registers from any other register and from any of these registers to any other register. They are used to store constants or in- termediate answers which may be required at a later stage in the calculation. An indicator zero appears on the far left; in the illustration it is shown aligned with the MQ Register. This ineJicates which register has been selected as the FROV' register. When the TRANSFER key is depressed, the contents of the reg- ister, the FROM register, will automatically be transferred to the TO register. In one register, one of the 24 digits will appear unusually bright. This is the register selected as the TO register. In the illustration, this is shown as the initial zero of the Accumulator Register. right or left by the FORWARD SPACE and BACK SPACE keys. The position which is shown as bright can be moved The position of the bright digit indicates the next position for number entry. If the number 2 key were depressed, the bright zero would be converted to a 2, and the next zero to the right would become the bright digit. The operation of these various keys is explained in detail later in this book, as well as the use of these keys to correct erroneous data al ready entered. Documenent Scan Courtesy The Old Calculator Museum http://oldcalculatormuseum.com 2 Keyboard The labeling on the various keys is self-explanatory and the remainder of this book is devoted to illustrating the function and application of the keyboard. For your convenience the keys are grouped by function. The left hand group of keys controls transfer operations, the central group of keys control data entry, and the right hand group of keys control arithmetic operations. A quick reference list of the basic calculator commands and operations is given on the back cover. Since the notation is used in other places throughout the book, it is explained in the following paragraphs. As an exainple;,considerthe. foUowingllsh()rthand li notation (Entry) + (Acc.) - (Acc.)

OVERFLOW When the "Overflow Lock Off" switch is in the "off" (up) position, the overflow lockout is inhibited. Overflow nonnall y occurs when the answer to an operation exceeds the capacity of the machine, as for example, when two seven digit numbers are multiplied together with the decimal in the center position (only 12 digits available for product). Overflow indication consists of all digits ~ LJ in the display intensified, plus a line of zeros at the far right edge of the display.

Documenent Scan Courtesy The Old Calculator Museum http://oldcalculatormuseum.com 18 Please observe the following precautions in using the Wyle SCIENTIFIC electronic calculator. 1. Keep dust cover on calculator whe~ machine is not in use. 2. Do not place dust cover on calculator when machine is turned on. This'blocks air flow to the machine and the internal rise in temp~rature may damage circuits. 3. Do not lift or move the calculator while it is running. After turning the calculator off, allow two minutes before lifting or moving. Failure to observe these precautions may damage the memory disc. 4. Remove and clean the air filter (located on the bottom of the calculator) every three months. Use vacuum cleaner or wash with soap and water. Be su're filter is dry before replacing it in the calculator. If your calculator does ~ot operate properly, check the following possibilities. 1. If cooling fan is not running a. Check AC ,line cord and plug. b. Check AC outlet. c. Check calculator fuse (on back of calculator case). 2. If cooling fan is running but there is no display a. Be sure either a jumper plug or some input/output device is plugged into I/O socket on back of calculator case. 3. If display is bright but numbers cannot be entered from keyboard a. Check if any key is stuck down. \ b. Machine may be locked in overflow. Press any TO key to resume normal operation.
