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.
