Appendix

Avoid using a telephone during a thunderstorm. There might be a slight chance of electric 
shock from lightning.

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. The user should not plug the phone into a power outlet, and should not put a charged 
handset into the cradle, if the phone is located in an environment containing concentrations 
of flammable or flame-supporting gases, unless there is adequate ventilation. A spark in such 
an environment could create a fire or explosion. Such environments might include: medical 
use of oxygen without adequate ventilation; industrial gases (cleaning solvents; gasoline 
vapors; etc.); a leak of natural gas; etc.

Do not use this product near water, or when you are wet. For example, do not use it in a

Do not use liquids or aerosol sprays for cleaning. If the product comes in contact with any 
liquids, unplug any line or power cord immediately. Do not plug the product back in until it
