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 (ѿ)
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.
