Important safety information
When using your equipment, basic safety precautions should always be followed to
reduce the risk of fire, electric shock and injury, including the following:
Safety information
• Read and understand all instructions in the user’s manual. Observe all markings on
the product.
• Use only with UL listed phones.
• Avoid using the product during a thunderstorm.
There may be a slight chance of
electric shock from lightning.
• Do not use the product 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.
• 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.

section of this user’s manual.
If you cannot solve the problem, or if the product is
damaged, refer to the

as may be directed in your user’s manual. Opening the product or reassembling it
incorrectly may expose you to hazardous voltage or other risks.
• This power adapter is intended to be correctly oriented in a vertical or floor mount
position.
The prongs are not designed to hold the plug in place if it is plugged into
a ceiling, an under-the-table or a cabinet outlet.
