If you try to continue using the calculator, it will automatically turn off in order to protect

memory contents. You will not be able to turn power back on until you replace batteries.

Be sure to replace the batteries at least once every one year, no matter how much you use the

calculator during that time.

The batteries that come with this calculator discharge slightly during shipment and storage.

Because of this, they may require replacement sooner than the normal expected battery life.

Replacing Batteries

Precautions:

Incorrectly using batteries can cause them to burst or leak, possibly damaging the interior of

the calculator. Note the following precautions:

• Be sure that the positive (+) and negative (–) poles of each battery are facing in the proper

directions.

• Never mix batteries of different types.

• Never mix old batteries and new ones.

• Never leave dead batteries in the battery

compartment.

• Remove the batteries if you do not plan to

use the calculator for long periods.

• Never try to recharge the batteries supplied

with the calculator.

• Do not expose batteries to direct heat, let

them become shorted, or try to take them

apart.

(Should a battery leak, clean out the battery compartment of the calculator immediately, taking

care to avoid letting the battery fluid come into direct contact with your skin.)

Keep batteries out of the reach of small children. If swallowed, consult with a physician

immediately.

To replace the batteries

• Never turn on the calculator while the batteries are removed or not loaded correctly. Doing

so can cause memory data to be deleted and malfunction of the calculator. If mishandling

of batteries causes such problems, correctly load batteries and then perform the restart

operation to resume normal operation.

• Be sure to replace all four batteries with new ones.

1. Press

(OFF) to turn off the calculator.

Warning!

• Be sure to turn the calculator off before replacing batteries. Replacing batteries with power

on will cause data in memory to be deleted.
