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
must be used
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 1 )
3. When any number is divided by zero. (Ex. 5 0
)

approximately 2,500 hours at 25°C(77°F) with no
operation battery installed, and the AC adaptor not
connected.
* When the memory protection battery is weak, the
date/time setting is initialised (1/1/2005, 12:00:00
a.m.).
Verify the date/time setting in the date/clock display
mode after replacing the operation battery or when
connecting the AC adaptor with no operation battery
installed.
If the date/time setting is modified or incorrect,
promptly replace the memory protection battery with
new one.
(The life of the pre-installed battery may be shorter
than expected because of the time the calculator
spends during shipment.)
Method of battery replacement
Use one lithium battery (CR2032).
Caution: Replacing the battery will clear the date
and time settings, and the stored tax rate.
