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.
