Read and understand all instructions.
Follow all warnings and instructions marked on the product.
This product can be hazardous if immersed in water. To avoid the possibility of electric
shock, do not use when you are wet. If you accidentally drop it into water, do not retrieve it
until you have first unplugged the line cord from the modular wall jack. Do not plug the
telephone back in until it has dried thoroughly.
Avoid using the telephone (other than a cordless type) during electrical storms in your
immediate area. There is a remote risk of electric shock from the lightning. Urgent calls
should be brief. Even though your telephone company may be using protective measures to
limit electrical surges from entering your building, absolute protection from lightning is
impossible.
If you suspect a gas leak, report it immediately, but use a telephone away from the area in
question. The telephone’s electrical contacts could generate a tiny spark. While unlikely, it
is possible that this spark could ignite heavy concentrations of gas.
Never push objects of any kind into this telephone through housing slots as they may touch
hazardous voltage points or short out parts that could result in a risk of electric shock. Never
spill liquid of any kind on the telephone.
To reduce the risk of electric shock, do not disassemble this product. There are no user
serviceable parts inside. Opening or removing covers may expose you to hazardous voltages.
Incorrect reassembly can cause electric shock when the telephone is subsequently used.
Disconnect the cords on this product before cleaning. Do not use liquid cleaners or aerosol
cleaner. Use a damp cloth for cleaning.
Slots and openings in the housing and the back or bottom are provided for ventilation to
protect it from overheating, these openings must not be blocked or covered. The opening

not be placed in a built-in installation unless proper ventilation is provided.
