Precautions for handling batteries
Pull down the notch, then lift the battery cover up to remove it.
• 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.
Part names and Functions
• 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.
replacing the memory backup battery
Once every 5 years, the lithium battery will need to be replaced. The lithium battery is used to
maintain the memory of the calculator.
note: Do not remove the lithium battery while the unit operation batteries are removed;
otherwise all the calculator's stored memory will be lost.

Calculation accuracy
In principle, calculation errors are ±1 of the last digit. (In case of exponential display, the
calculation errors are ±1 of the last digit of the mantissa display.)
However, a calculation error increases in continuous calculations due to accumulation of each
calculation error. (This is the same for a

are performed internally.)
Additionally, a calculation error will accumulate and become larger in the vicinity of inflection
