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”).

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.
