Contact the fault service (Tel 175).
• Clean the outside of the phone at regular intervals, using a damp, soft cloth. For heavy soil-
ing, dab a little washing-up liquid on the cloth. Do not use abrasive agents or solvents since
they may damage the housing surface. Make sure no liquid penetrates the phone during
cleaning.
