WARNING! To reduce the possibility of electric
shock, do not expose your phone to high humidity
areas, such as a bathroom, swimming area, etc.
Caution: Use only LG-approved batteries and
desktop chargers to avoid damage to the phone.
Using other batteries or chargers voids your
warranty and may cause an explosion.
Caution: Do not use batteries and desktop chargers
for other than the intended purposes.
Never store your phone in temperatures less than
-4° F or greater than 122° F, such as outside during
a snowstorm or in your car on a hot day. Exposure
to excessive cold or heat may result in phone
malfunction, damage and/or failure.
Use caution when using your phone near other
electronic devices. RF emissions from your mobile
phone may affect nearby inadequately shielded
electronic equipment. Consult manufacturers of any
personal medical devices such as pacemakers and
hearing aides to determine if they are susceptible to
interference from your mobile phone. Turn off your
phone in a medical facility or at a gas station.
IMPORTANT! Please read the TIA Safety Information
(see page 118) before using your phone.
