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.

In the “F” position, the answer is displayed in the floating decimal system.

PAPER FEED KEY:

When pressed, advances the paper roll.

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-addWhen 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 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.

(QS-1760H) (Ex. 9999999999 1 )

When the integer portion of the contents of the memory exceeds 12 digits. (QS-2760H/2770H) (Ex. 999999999999 1 )

4.When any number is divided by zero. (Ex. 5 0 )

DECIMAL SYSTEM

Input override decimal feature

The calculator operates on a principle of floating decimal entries with preset decimal answers.

1.An entry may contain up to 9 decimal places, regardless of the decimal selector setting. (QS-1760H)

An entry may contain up to 11 decimal places, regardless of the decimal selector setting. (QS-2760H/2770H)
