Especially about cordless telephones
• Privacy: The same features that make a cordless telephone convenient create some limitations.
Telephone calls are transmitted between the telephone base and the handset by radio waves,
so there is a possibility that your cordless telephone conversations could be intercepted by
radio receiving equipment within range of the cordless handset. For this reason, you
should not think of cordless telephone conversations as being as private as those on
corded telephones.
23
• Electrical power: The telephone base of this cordless telephone must be connected to a
working electrical outlet which is not controlled by a wall switch. Calls cannot be made from
the handset if the telephone base is unplugged, switched off or if the electrical power
is interrupted.
• 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 interference.
• 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.
