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 must be used to clear the calculator.
Also, in rare cases, printing may stop midway and the indication "E" will 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 )

REPLACEMENT OF BATTERY FOR MEMORY PROTECTION

Time for battery replacement
Life of the memory protection battery is 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 initialized (1/1/2008, 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.)

How to change the battery
Use one lithium battery (CR2032).

Replacing the battery will clear the date and time settings, and the stored tax rate.

1. Set the power switch to the "OFF" position, and disconnect the AC adaptor.
2. Remove the battery cover on the back of the unit. (Fig. 1)
   
   
3. Remove the exhausted battery and install one new lithium battery. Wipe the battery well with a dry cloth and place the plus "+" side upward. (Fig. 2)
   
   
4. Replace the battery cover by reversing the removal procedure.
5. Press the RESET switch on the back of the unit (See "RESETTING THE UNIT").
