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 telephone during a thunderstorm. There might be a slight chance of electric 
shock from lightning.
Do not use a telephone in the vicinity of a gas leak. Under certain circumstances, a spark 
may be created when the adapter is plugged into the power outlet, or when the handset is 
replaced in its cradle. This is a common event associated with the closing of any electrical 
circuit. The user should not plug the phone into a power outlet, and should not put a charged 
handset into the cradle, if the phone 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, read the Troubleshooting section on  
pages 137-149 of this user’s manual. If you cannot solve the problem, or if the product is 
damaged, refer to the Limited warranty section on pages 159-160. 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 voltages or other risks.
Replace batteries only as described in your user’s manual (page 11). Do not burn or puncture 
batteries — they contain caustic chemicals.
The power adapters are 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, 
under-the-table or cabinet outlet.
