Important information

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.
