Quick Start
-------------------------------------------------------------
We will not duplicate the HP-15C manual here. Instead, we will provide enough information to get you started. There are a number of guides and references available for the HP-15C in bookstores and other places where Hewlett-Packard calculators are sold.
If you want to get the most from the calculator, we suggest you read the "HP-15C Owner's Handbook" published by the Hewlett-Packard Company which covers all the basic and advanced functions, operations, and programming of the HP-15C.
*The KK-15C Keyboard
The keys on KK-15C are arranged in the same ordering as on the HP-15C. The primary function of a key is in the middle of a group. The alternate functions are the upper and lower functions which are specified by pressing the appropriate prefix key. To specified the upper function, press the "f" prefix key ([f]), then press the function key. To specified the lower function, press the "g" prefix key ([g]), then press the function key. The middle function does not require the use of a prefix key.
*Newton Interface
To access the Info Button (the i button) Picker which contains "About", "Prefs" and "Register" commands, press [f] [ON].
*The Memory
To reset the calculator (clearing continuous memory)
1. Uncheck the option "Turn calculator on when open" in the Prefs.
2. Turn off the calculator by pressing [ON].
3. Press [-] [ON]. "Pr Error" is displayed.
*Entering Numbers
To enter numbers, simply press the digit keys in sequence. For large numbers, enter the mantissa, press [EEX] (enter exponent), then enter the exponent.
To change the sign of a number in the display, press [CHS] (change sign).
*Clearing Numbers
Press [CLX] to clear the display to zero. If the digit entry has not been terminated by [ENTER] or other functions, press [<-] to delete only the last digit in the display. Otherwise [<-] acts like [CLX].
*The Display
The KK-15C has three display formats:
- Fixed decimal display ([FIX]).
- Scientific Notation Display ([SCI]).
- Engineering Notation Display ([ENG]).
To change the format or the number of digits displayed to the right of the decimal point, press [f] [FIX] or [f] [SCI] or [f] [ENG] followed by [0] through [9].
To change digit separator display (swap period and comma between the decimal point and group of three digits):
1. Uncheck the option "Turn calculator on when open" in the Prefs.
2. Turn off the calculator by pressing [ON].
3. Press [.] [ON].
*RPN and Arithmetic Calculations
KK-15C uses a key-command ordering called Reverse Polish Notation (RPN), also called postfix notation. An arithmetic calculation involves two numbers and an operation (+, -, x, or Ö). For example, to add the numbers 2 and 3, press [2] [ENTER] [3] [+].
The number in the display is said to be in the X-register. When the [ENTER] is pressed, a number gets copied from X-register to Y-register. The previous number in Y-register gets copied to Z-register and the previous number in Z-register gets copied to T-register. The previous number in T-register is lost. Most functions use numbers stored in these registers to perform the calculations.
*Numeric Functions
[g] [¹] inserts the value of pi into the display (X-register).
Number Alteration Functions
[g] [INT] returns the integer part of the value in the X-register.
