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 the wireless telephone 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.
About wireless mics
• Privacy:
The same features that make a wireless mic convenient create
some limitations. Calls on conference phones are transmitted between
the base unit and the wireless mic by radio waves, so there is a possibility
that the wireless mic conversations could be intercepted by radio receiving
equipment within range of the wireless mic. For this reason, you should not
think of conference phone conversations as being as private as those on
corded telephones.
• Electrical power:
The base unit of this conference phone must be
connected to a working electrical outlet. The electrical outlet should not be
controlled by a wall switch. Calls cannot be made from the conference phone
if the base unit is unplugged, switched off or if the electrical power
is interrupted.
• Potential TV interference:
Wireless mic operates at frequencies that may
cause interference to televisions and VCRs. To minimize or prevent such
interference, do not place the base unit near or on top of a TV or VCR. If
interference is experienced, moving the wireless mic farther away from the
TV or VCR often reduces or eliminates the interference.
• Rechargeable batteries:
Exercise care in handling batteries in order not to
create a short circuit with conducting material such as rings, bracelets and
keys. The battery or conductor may overheat and cause harm.
• 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.
