“P” position: The calculator functions as a print/display calculator. (Print
mode)
“•” position: The calculator functions as a display calculator. (Non-print
mode)
Mode change print:
When changing the print mode selector, the following print will appear.
“• • • .... • • • –P” (red print): When changing the selector from P to •.
“• • • .... • • • +P” (red print): When changing the selector from • to P.
GRAND TOTAL / RATE SETTING MODE SELECTOR:
“GT” position: This selector will accumulate the following:
(The symbol “+” will be printed.)
1. Addition and subtraction totals obtained with the or
key.

.
– 3 –
• A maximum of 4 digits can be stored (decimal point is
not counted as a digit).
Note: • Be sure to set this selector to the “•” position after storing an
each rate.
• Only one rate can be stored. If you enter a new rate, the previous
rate will be cleared.
ADD MODE SELECTOR:
“A/+” position – Effective only in addition and subtraction:
Use of the A/+ mode permits addition and subtraction of
numbers without an entry of the decimal point. When the
A/+ mode is activated, the decimal point is automatically
positioned according to the decimal selector setting.
EXAMPLES: Set A/+- • -A/x to A/+
A. Set decimal to 2
Enter 123456 Tape prints 1,234.56 +
B. Set decimal to 3
Enter 123456 Tape prints 123.456 +
Use of the , , and keys will automatically override
the Add mode and decimally correct answers will be
printed at the preset decimal position.
EXAMPLES: Set A/+- • -A/x to A/+, 5/4
A. Set decimal to 2
Enter .1234 Tape prints 0.1234 ×
100 100.=
12.34
B. Set decimal to 3
Enter 2 Tape prints 2
3 3.=
C. Set decimal to 2
Enter 123 Tape prints 1.23 +
10 10.00 +
Note that decimal point was entered.
“A/x” position – Multiplication and division:
When the A/x mode is activated, the number entered
before or key will override the add mode. But the

number entered following or key and before (or
, , , , ) key will obey the decimal setting. This
is useful for invoicing.
EXAMPLE: Set A/+- • -A/x to A/x
Set decimal to 2
Enter 7 Tape prints 7.×
3 0.03 =
0.21
Note: Use of the key will automatically override the A/x
mode.
Addition and subtraction:
The A/x mode functions same as the A/+ mode.
“•” position: Neutral
ITEM COUNT MODE SELECTOR:
“IC±” position: 1) The counter will count the number of times that the
key has been pressed in addition.
Note: • Each time the key is used in subtraction, 1
will be subtracted from the count.
• The count is printed when the calculated
result is obtained.
• Pressing of the , , , or key
clears the counter.
2) When the grand total mode selector is in the ON
position (GT), the counter will count the number of
times that the calculation results have been stored in
the grand total memory. To print and clear the count,
press the key.
3) The memory item counter will count the number of
times that the key has been pressed in the addition.
Note: • Each time the key is used in the
subtraction, 1 will be subtracted from the
count.
• The count is printed when the memory is
recalled.
• Pressing of the key clears the counter.
“IC+” position: 1) The counter will count the number of times that the
or has been pressed in addition and subtraction.
Note: • The count is printed when the calculated
result is obtained.

• Pressing of the , , , or key
clears the counter.
2) When the grand total mode selector is in the ON
position (GT), the counter will count the number of
times that the calculation results have been stored in
the grand total memory. To print and clear the count,
press the key.
3) The memory item counter will count the number of
times that the or key has been pressed in
addition and subtraction.
Note: • The count is printed when the memory is
recalled.
• Pressing of the key clears the counter.
“•” position: Neutral, counter is turned off.
Note: The counter has a maximum capacity of 3 digits (up to ±999). If the
count exceeds the maximum, the counter will recount from zero.
FIRST FACTOR ACCUMULATION SELECTOR: (Only QS-2770H)
“FΣ” position: The first factor is automatically added to or subtracted from
the memory. A first factor means the first number in multiplication and division and each number is printed with “×I”
and “÷I” respectively.
Ex. 2 × 3 × 5 ÷ 6 =
12 ÷ 7 × 9 =
–56 × 4 × 0.5 =
“•” position: Neutral
CONSTANT MODE SELECTOR:
“K” position: The following constant functions will be performed:
Multiplication: The calculator will automatically remember the first
number entered (the multiplicand) and the instruction.
Division: The calculator will automatically remember the second
number entered (the divisor) and the instruction.
Add-on/Discount/Mark up:
The calculator will automatically remember the first
entered number and key functions for Add-on/Discount/
Mark up calculation.
“•” position: Neutral
ROUNDING SELECTOR:
“ ” position: An answer is rounded up.
“5/4” position: An answer is rounded off.

Note: You can also pull the paper manually.
RIGHT SHIFT KEY:
Operation of this key in entered numbers or calculated results shifts the
number one digit to the right together with the decimal point. Used for one
digit correction.
GRAND TOTAL KEY:
Prints and clears the “GT” memory contents.
NON-ADD/SUBTOTAL KEY:
Non-add – When this key is pressed right after an entry of a number in the
Print mode, the entry is printed on the left-hand side with the
symbol “#”.
This key is used to print out numbers not subjects to calculation
such as code, date, etc.
Subtotal – Used to get subtotal(s) of additions and/or subtractions. When
pressed following the or key, the subtotal is printed with
the symbol “◊” and the calculation may be continued.
By pressing this key even in the Non-print mode, the displayed number
is printed with the symbol “P”.
TOTAL KEY:
Prints the total of addition and subtraction with the symbol “ ”. This key also
serves as a clear key for the calculation register and resets an error
condition.

ERRORS
There are several situations which will cause an overflow or an error condition. When
this occurs, the error symbol “E” will be displayed and all keys will electronically lock.
The contents of the memory at the time of the error are retained.
If an “0䡠E” is printed on the tape at the time of the error, the key must be used to
clear the calculator. If an “E” with any numerals except zero is printed on the tape or if
an “E” is not printed on the tape, the error may be cleared with the or key and the
calculation can still be continued.
Error conditions:
1. Entry of more than 10 digits or 9 decimals. (QS-1760H)
Entry of more than 12 digits or 11 decimals. (QS-2760H/2770H)
This error can be cleared with the or key.
2. When the integer portion of an answer exceeds 10 digits. (QS-1760H)
When the integer portion of an answer exceeds 12 digits. (QS-2760H/2770H)
3. When the integer portion of the contents of the memory exceeds 10 digits.
