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.
Operating range
This cordless telephone operates with the maximum power allowed by the Federal Communications
Commission (FCC). Even so, this handset and telephone base can communicate over only a certain
distance - which can vary with the locations of the telephone base and handset, the weather, and the
layout of your home or office.
When the handset is out of range, the handset displays Out of range or no pwr at base.
If there is a call while the handset is out of range, it may not ring, or if it does ring, the call may not connect well
when you press . Move closer to the telephone base, then press to answer the call.
If the handset moves out of range during a telephone conversation, there may be interference. To improve
reception, move closer to the telephone base.
ECO mode
This power conserving technology reduces power consumption for optimal battery performance, according
to the distance between the telephone base and the handset. When the telephone base communicates
with the handset, ECO mode will be activated automatically.
