k 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 fl uid come into direct contact with your skin.)
Keep batteries out of the reach of small children. If swallowed, consult with a physician
immediately.
u 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 RESET
operation to resume normal operation.
• Be sure to replace both of the batteries with new ones.
Turning off the calculator while editing an eActivity and then changing batteries can cause
the data you are editing to be deleted. Be sure to save the eActivity data before turning off
the calculator and changing batteries.
