Do not short-circuit the charger. Short-circuiting the charger may cause
fire or malfunction of the charger.
If the power cord is damaged (for example, the lead is exposed or
broken), or the plug becomes loose, stop using the cable at once.
Otherwise, electric shock, short-circuit of the charger, or fire may occur.
Keep the charger dry. Once water or other liquid leaks into the charger,
electrical leakage or other faults may occur.
Do not use the charger in a dusty and damp environment. Keep the
power cord away from any heating appliance.
Ensure the charger is properly plugged into the power socket properly
when charging the battery. Improper insertion may result in electric
shock, fire, or explosion. To unplug the charger, pull the plug off rather
than tear the power cord.
Use the AC power supply defined in the specifications of the charger.
An improper power voltage can cause fire or malfunction of the charger.
Do not place any heavy object on the power cord of the charger. Do not
damage, change, or pluck the power cord. Otherwise electric shock or
fire may occur.
When you are charging the battery with the charger, do not touch the
plug, power cord or the charger with a wet hand. Otherwise, electric
shock can be caused.
Once the liquid such as water leaks into the charger, remove the plug of
the charger from the socket immediately. Otherwise, overheating, fire
and other malfunction may occur.

THIS DEVICE MEETS THE GOVERNMENT'S REQUIREMENTS FOR
EXPOSURE TO RADIO FREQUENCY ELECTROMAGNETIC FIELD.
Your cordless phone is a low-power radio transmitter and receiver. When it
is turned on, it emits low levels of radio frequency energy (also known as
radio waves or radio frequency fields).
Governments around the world have adopted comprehensive international
safety guidelines, developed by scientific organizations, e.g. ICNIRP
(International Commission on Non-Ionizing Radiation Protection) and IEEE
(Institute of Electrical and Electronics Engineers Inc.), through periodic and
thorough evaluation of scientific studies. These guidelines establish
permitted levels of radio wave exposure for the public. The levels include a
