Important safety information

This symbol is to alert you to important operating or servicing instructions that may appear in this user’s manual. Always follow basic safety precautions when using this product to reduce the risk of injury, fire, or electric shock.

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 charger into a power outlet, and should not put a charged headset into the cradle, if the headset charger 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 wet basement or shower, or next to a swimming pool, bathtub, kitchen sink, or laundry tub. 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 has dried thoroughly.

•Install this product in a protected location where no one can trip over any line or power cords. Protect cords from damage or abrasion.
