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. 228
