The Keyboard
The RPD-95 has 65 keys, each with a primary function. In addition, many keys have alternate functions. The five definable function keys provide additional selections. Some functions use "fields" as labels or addresses for the function to be performed.
Primary Functions
The program functions of each key is printed on the key.Primary Function ---->
In this guide, primary key functions are illustrated by square brackets around the function. Example: [ EE ]
Second Functions
Some of the keys have a second function labeled above the key in yellow. To use the second function of a key, press [ 2nd ] before pressing the key. For example, given the key above, the second function of the [ EE ] is "ENG".In this guide, second functions are enclosed in square brackets and preceded by the [ 2nd ] key symbol. Example: [ 2nd ] [ ENG ].
Fields
Many functions must be followed by identifying data, called fields, to complete the function. For example, to store a number in data register 4, you must enter [ STO ] 004. The register address 004 is the field.Alpha Mode Characters
Some keys have an alphabetic or punctuation character labeled above the key. These symbols can be accessed only through the alpha mode or when entering alpha fields, such as file names or labels. The alpha mode is discussed in the RPD-95 Programming Guide.In this guide, and the programming guide, references to alpha characters are boldfaced, without brackets. For the key above, the alpha character is { .
Inverse Functions
Some keys have an inverse function that generally produces the opposite effect of the primary function. To use the inverse function of a key, press [ INV ] before pressing the key. For example, [ INV ] [ SIN ] is the arcsine function.A few functions are implemented using [ INV ] with the second function of a key. For example, the key sequence [ INV ] [ 2nd ] [ ENG ] returns the calculator from engineering notation to standard notation. When using these functions, the [ INV ] and [ 2nd ] keys may be pressed in either order.
Definable Function Keys
The functions of the [ F1 ] through [ F5 ] keys are defined by certain other keys. Labels appear in the display directly above the keys to indicate their functions.In this manual, references to the functions of definable keys are illustrated with the label enclosed in curly brackets. Example: { F-C }.
When you press certain keys ( such as [ CONV ] or [ NUM ] ), the labels above the function keys offer you a system menu of available selections. You can continue using the menu as long as it remains in the display.
For example, when you press the [ CONV ] (conversions) key, a menu appears. You then select the type of conversion you want from the menu. Some of the conversions you select offer other menus.
