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 the power plug not connected to the socket.
* When the memory protection battery is weak, the date/time setting is initialized
(1/1/2006, 12:00:00 a.m.).
Verify the date/time setting in the date/clock display mode when connecting
the power plug to the socket.
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.
1) Turn the power switch OFF and unplug the power supply plug from the
outlet.
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).
After battery replacement
Connect the power supply plug to an outlet and turn the power switch ON.
Check that 0. is displayed. If 0. is not displayed, remove the battery,
reinstall it, and check the display again.
Readjust date, time, and tax rate settings.
On the battery replacement date label found on the back of the unit, write
down the month and year when the battery is replaced, as a reference for
the next battery replacement.
Precautions on battery use
Do not leave an exhausted battery in the equipment.
Do not expose the battery to water or flame, and do not take it apart.
Store batteries out of the reach of small children.
