Casio FX-7400GII User Manual

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.
I 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.
S 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 M(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.
