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 may be a slight chance 
of electric shock from lightning. 

 

Do not use the telephone 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 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 liquid, 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 in 

your product’s manual. If you cannot solve the problem, or if the product is 
damaged, refer to the Limited warranty. Do not open this product except as 

directed in your user’s manual. Opening the product or reassembling it 
incorrectly may expose you to hazardous voltages 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 cabinet outlet.

approved by the party responsible for compliance could void the user’s
