Safety information
Read and understand all instructions in the user’s manual. Observe
all markings on the product.
Avoid using this product 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.
Do not use this product near water, or when you are wet. For
example, do not use the lifter 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 is 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.
