Menus, Menu Items, and Assigning Values to Menu Items
Many of the calculator's functions are located within menus. A menu is a catalog which permits you to select an item from a list of options. To access a menu, press the key, or secondary-function, key combination for the menu in which you wish to work. To exit a menu, press
O
. For example, to access the Bond menu, press
B
. Once opened, you can scroll through the items in the menu by pressing
<
or
>
repeatedly. When you arrive at the last item in a menu, pressing
<
returns you to the first item. Similarly, pressing
>
once on the first menu item scrolls to the last item in the menu. Some menus have sub-menus. If an item represents a sub-menu, pressing
I with that menu item displayed opens the sub-menu.
Most menu items consist of two parts: a name and an associated number. For
example, the Fixed item in the Break-even menu is displayed in Figure 3.
Figure 3
The large (=) annunciator shows that the value assigned to Fixed is 120,000.
If you perform a calculation with this item displayed by pressing
1+2= for example, Fixed is still selected as the current item, but the large (=) annunciator is now turned off, indicating the 3 is not the value assigned to Fixed. See: Figure 4.

Figure 4
At this point, to return to the display of the Fixed menu item shown in
O
.
There are four types of menu items:
1.
2.
3.
4.
Read/write. Read/write menu items, such as Fixed in the Break-even menu shown above, are easily recognizable, because when they are selected, both the INPUT and small (=) annunciators are lit. When lit, these annunciators indicate that keying in a number and pressing
I
will store the entered number in the displayed menu item.
Pressing
=
(outside of a mathematical operation) calculates the value for that item based on available data.
Read-only. Read-only items such as Internal Rate of Return (IRR% ) in the IRR menu are display-only; they are values computed internally by the calculator.
Write-only. Write-only items, such as investment interest rate (Inv. I% ) in the Net Present Value (NPV) menu, are similar to read/write items in that the INPUT annunciator is lit when these items are selected, indicating that keying in a number and pressing
I
stores that number in that menu item. However, the
=
key does not calculate a value for that item.
Special items. Special items, such as the Degree/Radian option in the
Mode menu, the items of the Reset menu, and the items of the Percent
Calculation (%calc ) menu perform an action when
I
is
Getting 9
pressed. Depending on the menu, this action can be the selection of a sub-menu (%calc), changing a mode or setting (Mode menu), or erasing data (Reset menu).
The Reset Menu
The Reset menu allows you to reset some, or all, of the menu items, variables, and registers to their default values.
To open the Reset menu, press
:x
.
TVM displays on the top line. Press
< or
> repeatedly to scroll to a specific item. To validate a choice and reset the selected items, press
I
.
Press
O to cancel. If you select the command to reset the cash flow (Cash Flow), statistics (Stats ), or all values
(All ) items, you will be prompted to confirm your choice. At the Del. All?, Del.
Data?, and Del. CF? prompts, press
I
again to confirm the reset, or
O to cancel.
While working within a specific menu, pressing
:x takes you directly to the item of the Reset menu that allows you to reset that specific menu. For example, if you are working in the Bond menu and you wish to reset all your entries in the Bond menu, with any item of the Bond menu displayed, press
:x
.
Bond displays on screen. At this prompt, pressing
I resets the Bond menu and returns you to the last item you were working with in the
Bond menu.
Notes about Special Menus
The Mode, Memory, Math and Reset menus are unique menus; they allow you to work in another menu simultaneously without having to exit. For example, if you were working in the Bond menu prior to entering one of these menus, pressing
O to exit returns you to your previous work in the Bond menu.
10 Getting Started
Memory and the Memory Menu
The Memory menu contains the following items: memories 1–9 (Mem 1–9) and 0 (Mem 0), Cash Flow, Statistics (Stats), and Memory. To enter the menu, press
:t
. Press
< or
> repeatedly to scroll through the items starting with memory 1 (Mem 1).
The Cash Flow and Statistics menus share the same memory and are limited to a combined total of 50 memory slots. The number displayed with Memory refers to the number of remaining memory slots. When the cash flow or statistics items are displayed, a number also appears on the bottom line. This number indicates the number of memory slots used by the menu.
Pressing
I with this number displayed resets the memory of the displayed menu item and erases all entered data. Since entering data in these menus can represent a significant amount of work, you will be asked to confirm your choice. At the Del.Data? or Del.CF? prompts, press firm, or
O to cancel.

Storing and Recalling Numbers
To store a number in the display, press
:$
, followed by the number of the memory in which you wish to store that number, (1-9, or 0). To recall the number later on, press
L
followed by the memory number. When a memory item is displayed, you can key in a new number and modify the value of the memory by pressing
I
.
Reverse Polish Notation (RPN) Mode
The following information is a brief overview of how RPN works. In RPN mode, numbers are entered first, separated by pressing
I
, followed
Getting 11
by an operation key. Pressing the
I
key is optional after entering a number, if the next key pressed is an operation. Each time you press an operation or function key in RPN, the answer is calculated immediately and displayed. For example, suppose you wanted to add two numbers in RPN, 1 and 2. Press
1I2+
. The result, 3.00, is calculated and displayed immediately.
There are four special registers used for storing numbers during calculations, which are stacked on top of one another. Called the stack, these registers are designated X,Y, Z, and T. X is on the bottom, and T is on the top. Most often, the number in the display is the number in the X-register. Primarily, the numbers in the X- and Y-registers are the numbers used in calculations. The Z and
T registers are used for the automatic retention of intermediate results during chain calculations.
The
I
key separates numbers in the vertical stack and positions them in the X- and Y-registers, and, in addition to displaying intermediate results, this vertical arrangement of the stack allows you to copy and rearrange numbers without reentering them. For more complex problems requiring two or more operations, you do not need to enter parentheses to set operational priority. Key in numbers and operations inside the parentheses first, followed by those outside of the parentheses. If a problem has more than one set of parentheses, start by working with the operations and numbers in the innermost parentheses and work your way out.
For example, in RPN mode calculate
( ) × (
5 6
)
. Although this is a simple example, you can use the principles introduced here when working with more complex problems.
12 Getting Started
One way to calculate this problem is to key in the numbers and operations within the parentheses first, followed by the operation outside of the

*
Finishes the operation and displays the results.
Getting 13
Keys Used to Manipulate the RPN Stack
• Press
(
to perform a roll down of the stack. Note the small arrow on the key. A roll down moves the numbers in each register down one level, and the number in the bottom register moves up to the top of the stack.
• Press
D to perform a swap of the stack. Note the small symbol on the key. A swap operation exchanges the numbers of the X and Y registers of the stack.
• If no menu is selected, the
<
key performs the roll down operation, and the
>
key performs the swap operation.
Algebraic Mode
To perform the same example in Table 1-2 in Algebraic mode, use parentheses to set the order of operation, and key in the expression as it is written from left to right. Press
:u<
(five times) followed by
I to set the operating mode to Algebraic. The message on screen, Algebraic , confirms your choice. Press
O
to return to the default calculator screen, then press:
J
(3+4D*(5+6D
K
Note the expression displays on screen in the order in which it is keyed.
Press
= to return a result of 77.00.
Chain Mode
To perform the same example in Chain mode, use parentheses to set the order of operation as you did in Algebraic mode. Calculations in Chain mode are interpreted in the order in which they are entered. If you press an operation key,
+-/*
, after pressing
=
, the calculation is continued using the currently displayed value. Use parentheses to set the
