Placing the telephone
• Do not place your telephone on sensitive surfaces. Use a
non-slippery pad to protect your furniture from possible
damage.
• Do not place your telephone near sources of extreme heat,
e.g. near the radiator.
• Make sure that the line cable isn’t creased.
Cleaning the telephone
Use a slightly moistened (not wet) soft cloth or an anti-static cloth
and wipe off the telephone carefully. Do not use rough cloth,
solvents or aggressive cleaning fluids. Any damages of the
telephone, that are caused by non-observance of these
instructions, are not part of the liability given by the manufacturer.
