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 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 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 on 
pages 12-19 of this user’s manual. If you cannot solve the problem, or if the 
product is damaged, refer to the Limited warranty section pages 31-33. 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.
Replace batteries only as described in your user’s manual (pages 6-8). 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 or an under-the-table/cabinet outlet.
