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
/
FLASH
. Move closer to the telephone base, then press
/
FLASH
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.
Maintenance
Taking care of your telephone
Your cordless telephone contains sophisticated electronic parts, so it must be treated with care.
Avoid rough treatment
Place the handset down gently. Save the original packing materials to protect your telephone if you ever
need to ship it.
Avoid water
Your telephone can be damaged if it gets wet. Do not use the handset outdoors in the rain, or handle it
with wet hands. Do not install the telephone base near a sink, bathtub or shower.
Electrical storms
Electrical storms can sometimes cause power surges harmful to electronic equipment. For your own
safety, take caution when using electrical appliances during storms.
Cleaning your telephone
Your telephone has a durable plastic casing that should retain its luster for many years. Clean it only with a soft
cloth slightly dampened with water or mild soap. Do not use excess water or cleaning solvents of any kind.
