Regarding batteries, take into account the
following comments:
· Low battery power can cause any stored
information
completely lost. Always keep written records of
all important data.
· All data stored in memory is lost when you
replace the batteries. Write down important
data before replacing the batteries.
· Never charge batteries, try to take batteries
apart, or allow batteries to become shorted.
Do not expose batteries to direct heat or
dispose of them by incineration.
· Replace the batteries 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.
· Never mix batteries of different types, nor
should your mix new batteries with old ones.
· Keep batteries out of the reach of small
children.
· Remove the batteries if you do not plan to use
the calculator for a long time.
