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 fij 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 cif or H key and the calculation can still be continued. Error conditions: 1. Entry of more than 10 digits or 9 decimals. (QS-1760A) Entry of more than 12 digits or 11 decimals. (QS-2760A/2770A) This error can be cleared with the K) or key. 2. When the integer portion of an answer exceeds 12 (10: QS-1760A) digits. 3. When the integer portion of the contents of the memory exceeds 10 digits. (QS-1760A) (Ex. ri 9999999999 1 ) When the integer portion of the contents of the memory exceeds 12 digits. (QS- 2760A/2770A) (Ex. 999999999999 1 Ej ) 4. When any number is divided by zero. (Ex. 5 FJ 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 11 (9: QS-1760A) decimal places, regardless of the decimal selector setting. 2.
