Note: • To prevent loss of stored data, DO NOT remove both the unit
operation and memory backup batteries at the same time.
• Please do not use rechargeable battery. This can lead to a
malfunction of the device.
• Batteries are factory-installed before shipment, and may be
exhausted before they reach the service life stated in the
specifications.
Precautions for
handling batteries
• Fluid from a leaking battery accidentally entering an eye could
result in serious injury. Should this occur, wash with clean water
and immediately consult a doctor.
• Should fluid from a leaking battery come into contact with your
skin or clothes, immediately wash with clean water.
• If the product is not to be used for some time, to avoid damage to
the unit from leaking batteries, remove them and store in a safe
place.
• Do not leave exhausted batteries inside the product.
• Do not fit partially used batteries, and be sure not to mix different
batteries types.
• Keep batteries out of the reach of children.
• Do not allow batteries to become completely exhausted; doing so
may cause the batteries to leak, and may damage the calculator’s
hardware.
• Do not throw batteries into a fire or water, as this may cause
them to explode.
