Operating Controls and Features
1. Decimal Selector. Allows selection of up
to eight decimal settings +, F, 0, 1, 2, 3, 4, 6.
For example, when set at 2, all totals and
results will contain two decimal places; at 0 no
decimals will be printed or displayed. In
Floating (F) decimal setting, results are
expressed at maximum decimal accuracy.
When working with dollars and cents, the
Decimal Selector can be set at Add Mode (+),
eliminating the need to enter the decimal
point.
2. D/PD/N Switch. Allows the choice of
operating in Display only (D position), or both
Print and Display without N Count (PD
position), or both Print and Display with N
Count (N position). Changing from Display
only position to Print and Display position will
print a row of red dots, the displayed value
with an audit of “P”, the Accumulator amount
(with N count if applicable), the Grand Total
amount (with N count if applicable) and a row
of red dots.
While in the D position or PD position, N Count
is “OFF”. In the N Count (N) position every
Plus, Minus, Equals Plus or Equals Minus key
depression is counted. The Accumulator and
its N Count or the GT N Count can be printed
by depression of the Subtotal or Total key. N
Count is always printed in red, left justified. If
the Equals key is depressed immediately after
the Subtotal or Total, the average of the
entries is printed.
NOTE: Correctable N Count. A depression
of Minus immediately following an erroneous
Plus or Equals Plus key depression will correct
the Accumulator and its N Count. If GT is on,
then the GT register and its N Count will be
corrected as well. A depression of Plus will
correct an erroneous depression of Minus or
Equals Minus in the same manner.
3. GT Switch. In the Neutral Mode ■position
any entry made with the Plus or Minus key and
any result obtained from depression of the
Equals Plus or Equals Minus key is either added
to or subtracted from the Accumulator.
In the Grand Total (GT) position any entry that
is added to or subtracted from the Accumulator
is also added to or subtracted from the GT
Accumulator. A second depression of the
Subtotal or Total key will give the grand
subtotal or grand total respectively of all
previously accumulated entries.
In the ◊position a running subtotal will be kept
in the display. The Subtotal and Total keys
operate as described with the GT Switch in the
GT position.
4. Grand Total Lamp. When illuminated,
indicates that an amount is being retained in
the Grand Total Accumulator.
5. Accumulator Lamp. When illuminated,
indicates that an amount is being retained in
the Accumulator.
6. Numeric Key Pad. Enter number 0 thru 9
and a decimal point just as you would write
them. The entry will not be printed until a
function key is depressed.
7. Plus Key. Adds an amount to the
Accumulator. To add the same amount more
than one time (repeat addition), enter the
amount once and depress the Plus key as
many times as necessary.
8. Minus Key. Subtracts an amount from the
Accumulator. To subtract the same amount
more than one time (repeat subtraction), enter
that amount once and depress the Minus key
as many times as necessary.
9. Total Key. Prints and clears the
Accumulator.
10. Subtotal Key. Prints but does not clear
the Accumulator.
11. Non-Add/Date Key. This key serves
three functions. First, it will print a live entry as
an identifier (such as an invoice number) or a
date. Second, it will store a live entry so that it
may be recalled for later use as an identifier or
constant. Third, when the D PD N selector
switch is in the D (display only) position press
#/Date to override the display only setting to
print an intermediate sequential calculation
result.
To print and store a date (e.g., 7/1/01), enter
the month and depress the Decimal Point key,
the date and Decimal Point, and the year and
depress the Non-Add/Date key. To recall the
contents of the Non-Add Register, depress the
Non-Add/Date key.
12. Times Key. To multiply, enter the first
number (multiplicand) and depress the Times
key; then enter the second number (multiplier)
and depress any Equals or Percent key, i.e.,
Equals, Equals Plus, Equals Minus, Percent, to
obtain a result.
13. Equals Key. Completes multiplication and
division.
14. Divide Key. To divide, enter the number
to be divided (dividend) depress the Divide
key. Then enter the second number (divisor)
and depress any Equals or Percent key, i.e.,
Equals, Equals Plus, Equals Minus, Percent, to
obtain a result.

15. Backspace Key. Deletes right most
character of a live entry, moving the remaining
display value one character to the right.
16. Clear/Clear Entry Key. (a) If the last
key depressed was numeric, depression of the
Clear/Clear Entry key will automatically clear
the entry. (b) If the last key depressed was
other than numeric, depression of the
Clear/Clear Entry key will cause a “C” to print
on the tape and will automatically clear that
entry, a pending multiplication or division
operation and the constant.
17. Percent Key. Calculates percentages and
has percent increase and net decrease
capabilities.
18. Equals Plus Key. Similar to the Equals
key; depression of this key yields the result of
a multiplication or division operation. The
result, however, will automatically be added to
the Accumulator.
19. Equals Minus Key. Similar to the
operation of the Equals Plus key; except
amounts are subtracted from the Accumulator.
20. PMT. Computes the monthly payment
given entry of PV, Rate and Term. May also be
used to enter a payment to solve for PV, FV,
Rate and Term.
21. TERM. Computes the period of time
required to repay an amount (PV). Used for
the entry of the TERM to solve for PMT, PV, FV
or Rate.
22. RATE. Used for the entry of Rate to solve
for PMT, PV, FV or TERM. Rate may be solved
for given the entry of PV, TERM and PMT.
23. PV (Present Value) . Used to enter the
Present Value (amount to be financed). May
also be used to compute the present value
given the entry of TERM, RATE and PMT, or
FV, RATE and TERM.
24. FV (Future Value). Computes Future
Value given the entry of PV, TERM and RATE.
Used to enter the Future Value to solve for PV.
25. SELL. From a known cost of goods and
desired gross margin, this key automatically
calculates and prints the amount of MarkUp
and the selling price. Used to enter the SELL
price to compute COST or MARGIN.
26. MARGIN. Used to enter the percent of
markup to be applied to the cost of an item.
When pressed with COST and SELL stored, will
compute the MARGIN and Percent of Markup.
27. COST. Used to enter the cost of an item.
When SELL and MARGIN are entered, pressing
COST will compute the COST.
28. Set Up Key. This unique key enables the
operator to select internal functions. To turn a
function on, the operator presses the Set Up
key followed by a numeric code entry at which
point the code number will print in black. To
turn a function off, the operator presses the
Set Up key followed again by the numeric code
at which point the code number will print in
red.
Set Up Key Codes
0: Sets calculator to Price/Price mode
when decimal selector at +.
00: Sets calculator to Units/Units mode
when decimal selector at +.
2: ΣT, Summation of Equals and Percent
results into the accumulator.
3: Running subtotal of the accumulator on
printer.
4: Two-column Addition.
5: Set rounding to TRUNCATE.
6: Set rounding to ROUND UP.
7: Set IDENTIFIER to print for each entry.
9: Recall Set Up Codes.
C/CE: Clear all Set Up Codes
+: Definable Add Mode
-: Nickel Rounding
▲: Paper Saver Mode
→: Change sign
Tax: VAT Tax
If both Set Up Code 0 and Set Up Code 00 are
ON, the calculator will be set to Price/Units
mode when decimal selector is at +.
29. Percent Change/Gross Margin Key.
Automatically compares any two amounts,
prints the actual numerical difference between
them, then calculates and prints the percent
change or the gross margin percentage.
30. Tax. This key serves two functions. First,
it stores a live entry as the tax rate. Second, it
will automatically compute the amount of tax
and amount of increase if pressed when no live
entry exists. For computation of decrease and
net, press following depression of the ÷key.
31. AMORTIZE. Prints the amortization
schedule for a period, selected range of
periods or the complete term of the loan.
32. Paper Advance.
On-Off Switch. Located on the side of the
calculator.
Decimal System. With the Pro, entries may
contain any combination of whole and decimal
digits, up to a maximum of 12 digits. However,
internally there is a 24-digit calculating
capability.
Add Mode. Set the Decimal Selector at Add
Mode (+) and the last two digits in any entry
followed by depression of the Plus or Minus
key will automatically be accepted as decimals.
Exception: if an actual decimal entry is made,
the calculator will accept and print it,
overriding the Add Mode (+) setting for that
entry.
Units/Price Mode. Designed for convenience
when calculating extensions. With the decimal
selector at Add Mode (+), all numbers entered
followed by depression of the Times key will be
accepted as whole numbers (units) unless an
actual decimal entry is made. The last number
entered followed by depression of the Equals,
Equals Plus or Equals Minus key will
automatically be accepted as having two
decimal places (dollars and cents).
Automatic Punctuation. On the tape and
display a comma automatically punctuates
every third whole digit to the left of the
decimal point.
Extended Capacity. If a result exceeds the
12-digit output capacity but does not exceed
the 24-digit calculating capacity, then the
result will be printed and displayed in scientific
notation.
For example: if a calculation result was
“222,333,444,555,000.” it would be expressed
in scientific notation as “2.22333444555 x
1014.” The printer would print the amount as
“2.2233344455514,” which indicates that to
write the extended capacity amount in
standard format, the decimal point must be
moved 14 digits to the right.
NOTE: On the Pro, the printer will show 12
significant digits and the exponent, while the
display will show 9.
Overflow. When a live entry contains more
than 12 digits (display and print capacity) or a
calculation result contains more than 24 digits
(calculating capacity), a series of red commas
will print indicating an overflow condition. The
display will show a “0”. The entry and/or result
is automatically cleared and the calculator is
ready for further calculations. Constants and N
Counts are not affected by this overflow
condition.
Underflow. In a result or total containing a
combination of whole and decimal digits, the
decimal point will shift right, regardless of
decimal setting in order to show the 12 most
significant digits. In results containing more
than 12 whole digits the calculator will go into
extended capacity.
Reverse Underflow. When a result should
normally be 0, based on the current decimal
setting, the calculator will float the result
showing as many digits as possible. For
example, the problem 2 divided by 625, with
the Decimal Selector set at (2), would yield a
result 0.00 without Reverse Underflow. With
this feature, however, a significant result of
0.0032 is given.
Automatic Calculation Mode Correction. If
you accidentally depress the Times key instead
of the Divide key (or vice-versa), it is not
necessary to clear the calculator. Merely
depress the correct function key (in this case,
the Divide key) and proceed with the
calculation.
Two Key Rollover. Allows an operator to
depress a numeric or function key while the
previous key is depressed or being released.
Clear Accumulator Indicator. If the
Accumulator contains the value zero, a unique
symbol (*) prints with the first entry into
Accumulator.
Square Root. The key sequence Divide,
Equals will automatically calculate the square
root of any positive entry, result or total.

Basic Financial Functionality
Important Operational Notes:
1. Amounts entered on the PV, TERM, RATE and PMT keys remain constants unless changed, i.e. a new
amount is entered that replaces the stored constant. It is recommended that the sequence (2.) below is used
prior to each calculation, or until you are familiar with the operation.
2. To clear the financial functionality PRESS C/CE then PV.
3. Once a payment has been calculated, pressing the Amortize key will cause an entire amortization schedule
to print. If sufficient information exists as constants, i.e. an amount is stored in PV, TERM, RATE and
PMT and Amortize is inadvertently depressed, the schedule will print. To stop the printing of the
Amortization schedule, PRESS C/CE during printing. The schedule will stop printing when the keyboard
buffer reads the depression of the C/CE key.
4. Solving for the RATE can take several seconds of computational time. During this time CALCULATE
will flash in the display.
Examples:
Solve for Payment.
Assume you are interested in purchasing a home for $250,000. The interest rate is 6%. You want to finance the
loan over a period of 180 months (15 years). Solve for Payment.

many months would be required to repay the loan? As shown below, it requires 196 months to repay the loan with a
remaining payment of $1306.31.

In the example above, the Amortize key was pressed when no live entry existed. This will cause the entire
amortization schedule to print.

To stop the printing of the Amortization Schedule, C/CE may be pressed. Amounts already in the keyboard buffer
will continue to print, but the schedule will cease printing when the C/CE key is read.
Rather than printing an entire amortization schedule, Monroe Pro enables you to select a month or range of months
for printing an amortization schedule. After finding the payment, or any of the other three variables, a selected
amortization schedule may be printed. If you desire a schedule for month 12 for example, enter 12 and press
Amortize. If you wish to print the schedule between months 24 and 28 for example, enter 24.28 then press
Amortize. NOTE: Amortize can only print if sufficient information exists (PV, Term, Rate) to compute Payment.
