Location of the telephone
• The telephone should be operated in a controlled environment with an
ambient temperature between 5°C and 40°C.
• To ensure good speakerphone quality, the area in front of the micro-
phone (front right) should be kept clear. The optimum speakerphone
distance is 50 cm.
• Do not install the telephone in a room where large quantities of dust
accumulate; this can considerably reduce the service life of the tele-
phone.
• Do not expose the telephone to direct sunlight or any other source of
heat, as this is liable to damage the electronic components and the
plastic casing.
• Do not operate the telephone in damp environments such as bath-
rooms.
