Safety information
f Read and understand all instructions in the user’s manual. Observe all markings on the product.
f CAUTION: Do not install the telephone base at a height above 2 meters.
f Avoid using a telephone during a thunderstorm. There may be a slight chance of electric
shock from lightning.
f Do not use a telephone in the vicinity of a gas leak. Under certain circumstances, a spark
may be created when the adapter is plugged into the power outlet, or when the handset is
replaced in its cradle. This is a common event associated with the closing of any electrical
circuit. In an inadequately ventilated environment, the user should not plug the phone into
a power outlet, nor put a charged handset into the cradle where there are concentrations
of ammable or ame-supporting gases. A spark in such an environment could create a
re or explosion. Such environments may include: medical use of oxygen without adequate
ventilation; industrial gases (cleaning solvents; gasoline vapors; etc.); a leak of natural gas; etc.
f Do not use this product near water or when you are wet. For example, do not use it in a wet
basement or shower, nor next to a swimming pool, bathtub, kitchen sink, and laundry tub.
Do not use liquids or aerosol sprays for cleaning. If the product comes in contact with any
liquid, unplug any line or power cord immediately. Do not plug the product back in until it
has dried thoroughly.
