Notes on batteries
• Do not charge a dry battery.
• Do not carry a battery together with coins or metallic objects. Heat can be generated by the
battery if its positive and negative terminals are accidentally shorted.
• When you are not going to use the unit for a long time, remove the batteries to avoid damage
from battery leakage or corrosion.
