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 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 may 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 58-62 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 70-72. 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.
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.
For pluggable equipment, the socket-outlet shall be installed near the equipment 
and shall be easily accessible.
