Important!

Incorrect use of batteries can cause them to burst or leak,

possibly damaging the calculator.

• Be sure to replace the battery at least once every three

years, regardless of how much the calculator is used. Old

batteries may leak, causing serious damage to the interior

of the calculator.

• The battery that comes with the calculator when you pur-

chase it is for testing only. It may not provide full service

life.

• Low bettery power can cause memory contents to become

corrupted or lost completely. Always keep written records

of all important data.

•Always be sure to load the battery with its positive ()

side facing up (so you can see it).

•Never try to charge batteries, take them apart, or allow

them to become shorted. Keep batteries away from direct

flame and heat.

•

Keep batteries out of the reach of small children. If

swallowed, consult with your physician immediately.

To replace the battery

1. Remove the screws that hold the

back cover in place, and then re-

move the cover.

2. Remove the old battery.

3. Install a new battery, making sure

that the positive () side is facing

up (so you can see it).

4. Replace the back cover and

secure it in place with the screws.
