Important safety information
• Potential TV interference: Some cordless telephones operate at frequencies that may cause 
interference to TVs and VCRs. To minimize or prevent such interference, do not place the telephone 
base of the cordless telephone near or on top of a TV or VCR. If interference is experienced, moving 
the cordless telephone farther away from the TV or VCR will often reduce or eliminate the 
• Rechargeable batteries: This product contains nickel-metal hydride rechargeable batteries. 
Exercise care in handling batteries in order not to create a short circuit with conductive material 
such as rings, bracelets, and keys. The battery or conductor may overheat and cause harm. Observe 
proper polarity between the battery and the battery charger.
• Nickel-metal hydride rechargeable batteries: Dispose of these batteries in a 
safe manner. Do not burn or puncture. Like other batteries of this type, if burned 
or punctured, they could release caustic material which could cause injury.
The RBRC™ Seal means that the manufacturer is voluntarily participating in an industry program to 
collect and recycle nickel-metal hydride rechargeable batteries when taken out of service within the 
United States. These batteries may be taken to a participating local retailer of replacement batteries 
or recycling center. Or you may call 1 (800) 8-BATTERY for locations accepting spent Ni-MH batteries. 
Precautions for users of implanted cardiac pacemakers
Cardiac pacemakers (applies only to digital cordless telephones): 
Wireless Technology Research, LLC (WTR), an independent research entity, led a multidisciplinary 
evaluation of the interference between portable wireless telephones and implanted cardiac 
pacemakers. Supported by the U.S. Food and Drug Administration, WTR recommends to physicians that:
Pacemaker patients
Should keep wireless telephones at least six inches from the pacemaker.
Should NOT place wireless telephones directly over the pacemaker, such as in a breast pocket, when 
it is turned ON.
Should use the wireless telephone at the ear opposite the pacemaker.
WTR’s evaluation did not identify any risk to bystanders with pacemakers from other persons using 
wireless telephones.
