Safety information
Read and understand all instructions in the user’s manual. Observe all
markings on the product.
Avoid using a headset during a thunderstorm. There may be a slight chance
of electric shock from lightning.
Do not use the headset to report a gas leak in the vicinity of the leak. Under
certain circumstances, a spark may be created when the adapter is plugged into
the power outlet, or when the headset is replaced in its cradle. This is a common
event associated with the closing of any electrical circuit. The user should
not plug the headset base into a power outlet, and should not put a charged
headset into the cradle, if the headset base 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.
