Paper and ribbon replacement:
Any standard 2-1/4 inch (57.15 mm) wide adding machine/calculator paper may be used for replacement.
Installtion of the ribbon:
Remove the ribbon cover by pulling up on the two plastic tabs at the back of the machine, the red lever located between the two ribbon spool retainer shafts is the sensor for the 'end of ribbon'-switch. It may be manually moved from one side to the other to install the ribbon spools.
Place one of the ribbon spools on the shaft matching the three tabs on the bottom of the spool with the slots in the calculator, press down gently uintil the catches on the end of the shaft snap into position.
Thread the ribbon and install the other spool.
replace the ribbon cover.
Installation of the paper:
Insert the plastic spindle (included with the calculator) through the paper roll and secure the spindle ends in the slots, the paper should roll from the bottom of the roll. The ribbon cover must be in place before loading the paper.
Insert the end of the paper in the slot. Depress the [PAPER FEED] key to advance the paper through the printer.
Lift the paper guide and as the paper appears in the print area, position the end of the paper under the paper guide. Push the guide down until it seats.

Key   

Description 

(On/Off)  

This switch is located on the right side, near the bottoml edge, of the calculator.
When power is turned on, the calculator prints zero(s) with a 'C' in the audit trail, spaces up auto, and is cleared ready for opeartion. 

PAPER FEED  

To advance the paper, depress this key,
the paper advances one space per depression, or continuously if held down.

PRINT  

When depressed immediately after antering a number, the number is printed with the '#'-symbol in the audit trail. No arithmetic operation is performed on the number.

C/CE  

Depressing the clear key performs the following functions, depending on the conditions:
a. Clears wrong number entries,
b. Clears the calculator except the memory and the item counter,
c. Clears overflow conditions.

+  

To add, depress [+] after entering a number.
Successive depressions without entering a number will add the last entry until a new number is entered (repeat addition).
For instance: to add 25 five times, enter 25 and depress [+] five times,
each depression adds 1 to the item counter.

-  

To subtract, depress [-] after entering the subtrahend.
Successive depressions without entering a number will subtract the last entry until a new number is entered (repeat subtraction).
For instance: to subtract 2 from 30 three times, enter 30 and depress [+]
enter 2, depress [-] three times.
each depression adds 1 to the item counter.

*  

Depression the [*] total key, prints and clears the contents of the accumulator memory. Be sure to drepress this key before beginning any problem involving addition or subtraction, or calculations using the accumulator memory,
i.e. [=+] or [=-]

(Rotated square)  

Subtotal key:
After a series of additions and subtractions, depressing this key prints but does not clear the contents of the accumulator memory.

X  

To perform multiplication operations, enter the multiplicand, depress [X],
then enter the multiplier.
For example: 3 [X] 5
For chain multiplication: 3 [X] 5 [X] 6 [X] 4
If [=], [=+] or [=-] is depressed immediately after entering the multiplier,
the multiplicand is retained for constant multiplication operations,
in calculating 3 [X] 5, 3 is established as a constant.
Successive multiplication by a constant is accomplished by entering a new multiplier and depressing [=], [=-] or [=+]

(Division)  

To perform division operations, enter the dividend, depress [(Division)],
then enter the divisior.
For example: 10 [(division)] 2
For chain division: 100 [(division)] 10 [(division)] 2 [(division)] 2.5
If [=], [=+] or [=-] is depressed immediately after entering the divisor,
the divisor is retained for constant division operations,
in the calculation 10 [(division)] 2, 2 is established as a constant.
Successive division by a constant is accomplished by entering a new dividend
and depressing [=], [=-] or [=+]
Multiplication and division may be chained,
for example: 4 [X] 5 [(division)] 6

=  

Depression [=] completes multiplication and division calculations and
prints the result.

%  

This key is used to compute percentages. It operates like the equals key when multiplying and dividing except that it causes the last entry to be divided by 100 before the desired arithmetic operation is performed.

N 
 COUNT 

Item count:
The item counter counts the number of entries which are added to or subtracted from the accumulator memory. The first depression of this key prints the current count without clearing the item counter. An immediate second depression prints the current count and also clears the counter.
Always clear the item before starting a problem involving averages or when an item count is desired.

EX 
  CHANGE 

Depressing this key changes the order after entry of the multiplicand and the multiplier, or the dividend and divisor, prior to completing the problem with [=]
See: Operands swapping

=+  

Depressing this key completes a multiplication or division problem and adds the result to the accumulator memory.
Successive multiplication and division by a constant can be accomplished axactly as with [=]
The result is added to the accumulator memory each time.

-+  

Depressing this key completes a multiplication or division problem and subtracts the result from the accumulator memory.
Successive multiplication and division by a constant can be accomplished axactly as with [=]
The result is subtracted from the accumulator memory each time.

(Decimal swithes)  

The position of the decimal point for the entries and results is determined by the two decimal position slider switches [F.A] and [0 1 2 3 4 6]
When the switch is in the 'F'-position, the decimal point is auto positioned in the answers to give the maximum accuracy within the 12-digit capacity.
When the switch is in the 'A'-position, the decimal point is auto positioned two places from the right in all addition and subtraction entries and in all answers.
For multiplication and division entries, the operator must enter the decimal point as he would normally. The operator can override the auto positioning during the entry by entering a decimal point at the desired location, however
the answer will still be in two decimal places.
When the switch is in the '.'-position, the decimal point is auto placed in the answer according to the position of [0 1 2 3 4 6]
The setting of the latter switch determines the number of decimal places in the answers.
When the Round off Switch [5/4 -] is in the '5/4'-position, the calculator will round off all the answers in accordance with the decimal setting,
When the Round off Switch [-] is in the '- (arrow down)'-position, decimals beyond the decimal settings are dropped from the answer,

C/CE  

A clear key has been provided to clear the calculator under certain conditions during operation. Depending on conditions, the clear key functions as follows:
A single depression of [C/CE] following a number entry clears the number from the calculator but does not effect the stored constants or the operations in progress.
If there is not an overflow condition, a single depression of [C/CE] following depression of [X], [(division)], [=], [EXCHANGE] or [%] clears the calculator except the accumulator memory and item counter.
If an overflow condition exists due to the entry of more than 12 digits, a single despression of [C/CE] clears the overflow condition but does not affect the stored constants or the operation in progress.
If an overflow condition exists due to the result of an arithmetic operation exceeding the capacity of the calculator (12 digits), or an apptempt to divide by zero, a single depression of [C/CE] clears the calculator except the memory and item counter.
A double depression of [C/CE] clears any operation in progress and clears the calculator except the accumulator memory and intem counter.
The accumulator memory is cleared by depressing [*]
The item counter is cleared by depressing [N COUNT] two times, successively.
