Installing telephones
Follow these safety instructions when installing telephone equipment:
• Never install telephone wiring during a lightning storm.

telephone line is disconnected at the network interface.
• Use caution when installing or modifying telephone lines.
Using telephones
These safety precautions are intended to reduce the risk of fire, electric shock,
and personal injury. Always follow these basic safety precautions when using
telephone equipment:
• Follow all warnings and instructions marked on the product.
• Before you clean a telephone, remove the plug from the wall outlet. Use
a damp cloth for cleaning. Do not use liquid cleaners or aerosol cleaners.
• Do not use the telephone near water (for example, near a tub or sink).
• Do not place the telephone on a piece of furniture that is unstable. The
telephone can fall, causing serious damage to the telephone.
• Slots in the Media Gateway and the telephone are for ventilation. These
slots protect the equipment from overheating. Never block or cover these
slots.
• Never block the openings on a telephone by placing it on a surface like a
bed, sofa, or rug. Never place a telephone near or over a radiator or heat
register. Do not place it in a built-in installation, unless there is correct
ventilation.
• Only operate a telephone from the type of power source indicated on the
marking label. If you are not sure of the type of power supply, check with
your distributor.
