lightning storms. When there is the possibility of thunderstorms, disconnect
the wall plug power adapter from the power socket.

must be easily accessible at all times and cables should be laid so they do
not present a trip hazard.
DANGER! Batteries
Insert the batteries with the correct polarity. Refer to the diagram inside the
battery compartment. Do not attempt to recharge the batteries and do not
dispose of the batteries in a fire. Do not mix battery types (old and new or
carbon and alkaline, etc.). Remove the batteries when the device is not to be
used for an extended period. Improper use could cause explosions or leaks.
Batteries must never be opened or deformed, as this could result in chemicals
leaking out which could cause injuries. If the battery fluid comes into contact
with the skin or eyes, rinse immediately with plenty of water and seek medical
aid.
Do not allow children to play with the batteries as they represent potential
choking hazards. Keep batteries out of reach of children. If a battery is
swallowed, seek medical help immediately.
