Batteries used in the calculator:
Type
Manganese battery
Lithium battery
With normal use, the AAA batteries last about 150 hours, and the lithium backup battery
lasts 5 years. The original batteries are included from the time of shipment and so
might run down sooner than these operating times.
CAUTION
To prevent loss of stored data, replace only one type of battery at a time.

(1) Battery precautions

• Keep the batteries out of the reach of children.
• When batteries become weak, remove them from the calculator immediately. If
depleted batteries are left in the calculator for any length of time, they might leak and
cause corrosion inside the calculator.
• Do not dispose of batteries in fire or water, as they may explode.

(2) Replacing the operating batteries

When the battery replacement message shown to the
right appears in the display, replace all four AAA
batteries as follows.
* If you continue using the calculator after the caution message has been displayed,
the power may not turn on when ˚ is pressed.
1. Turn off the calculator by pressing Ï ˙, then take off the hard cover.
