Errors; Replacement Of Battery For Memory Protection - Sharp EL-1750PIII Operation Manual

ERRORS

There are several situations which will cause an
overflow or an error condition. When this occurs, "E"
will be displayed. The contents of the memory at the
time of the error are retained.
If an "E 0." is displayed at the time of the error, "– – –
– – – –" will be printed in red and
to clear the calculator.
Also, in rare cases, printing may stop midway and
the indication "E" appear on the display. This is not a
malfunction but is caused when the calculator is
exposed to strong electromagnetic noise or static
electricity from an external source. Should this occur,
press the key and then repeat the calculation
from the beginning.
Error conditions:
1. When the integer portion of an answer exceeds 12
digits.
2. When the integer portion of the contents of the
memory or grand total memory exceeds 12 digits.
(Ex. 999999999999

approximately 2,500 hours at 25°C(77°F) with no
operation battery installed, and the AC adaptor not
