Be sure that the batteries are inserted correctly to avoid damage to the appliance. Always remove the batteries
when appliance will not be used for a long period of time, as this will cause leakage to the batteries and
subsequently damage to your set.
Use batteries of the same type. Never use different types of batteries together.
Do not throw the battery into the fire, or exposed to sunshine or the like.
If the liquid contained in the batteries comes in contact with eyes or skin, wash the area immediately and
carefully with clear water and consult a doctor
