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

on pages 31-36 of this user’s manual. If you cannot solve the problem, or if

the product is damaged, refer to thethe Limited warranty section on

pages 44-46. Do not open this product except 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.

Replace batteries only as described in your user’s manual (page 6). Do not

burn or puncture batteries — they contain caustic chemicals.

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.
