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 and no pwr at base
alternately.
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 /HOME. Move closer to the telephone base, and then press /HOME 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. The
ECO mode activates automatically whenever the handset is synchronized with the telephone base.
The handset shows ECO when the ECO mode activates.
