• Avoid exposing the telephone for direct sunlight or close to other
heat sources.
• Do not expose the telephone to open flame.
• Keep the telephone away from excessive heat and moisture.
• Moving the equipment rapidly between warm and cold tempera-

• If the liquid crystal display breaks, avoid injury by preventing the
liquid crystal from coming into contact with eyes, skin or mouth.
Prevent the liquid crystal from leaking out of the broken glass.
• In case of smoke or fumes, stop operating the product and turn it
off immediately. Unplug the mains adapter and remove the
batteries from the phone immediately. Continued operation may
result in fire or electrical shock.
