1.1 Safety Instruction

WARNING/CAUTION

To reduce the risk of fire or electric shock, do not
expose this product to rain or moisture. Do not use
this product near swimming pools or other water
bodies.

IMPORTANT

Before installing or operating this product read this
information.

1.2 Optimal Phone Performance

▶

Do not operate your product when holding the
antenna, or when someone is within four inches
(ten centimeters) of the antenna. Holding the
antenna affects call quality and may cause the
telephone to operate at a higher power level than
needed.

▶

For the best call quality, keep the antenna free from
obstructions and position the antenna straight up.

▶

Do not use the phone with a damaged antenna.
Have your antenna replaced by a qualified
technician immediately. Use only the Authorized
LGE Service Center-approved antenna. Non-

approved antennas, modifications, or attachments
could impair call quality, damage the phone.

▶

RF energy may affect improperly installed or
inadequately shielded personal medical devices
such as pace makers, hospital monitor. Consult the
manufacturer of any personal medical devices to
determine if they are adequately shielded from
external RF energy. Turn your terminal OFF in
health care facilities when any regulations posted in
the areas instruct you to do so.

Hospitals or health care facilities may be using
equipment that could be sensitive to external RF
energy.

▶

If this equipment does cause harmful interference
to radio or television reception, which can be
determined by turning the equipment off and on,
the user is encouraged to try to correct the
interference by one or more of the following
measures:

- Reorient or relocate the receiving antenna.

- Increase the distance between the radio or
television and the telephone.

- Connect the equipment into an outlet on a circuit
different from that to which the terminal is
connected.

- Consult your experienced radio/TV technician of
