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.
If this product does not operate normally, see the Troubleshooting section

burn or puncture batteries — they contain caustic chemicals.
This power adapter is intended to be correctly oriented in a vertical or
floor mount position.
