Replacement Of Battery For Memory Protection; Resetting The Unit - Sharp EL-2901PIII Manual De Manejo

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").
