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. The ECO
mode activates automatically whenever the handset is synchronized with the telephone base.
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 dampened cloth or cleaning solvents of any kind.
Remember that electrical appliances can cause serious injury if used when you are wet or standing in
water. If the telephone base should fall into water, DO NOT RETRIEVE IT UNTIL YOU UNPLUG THE
POWER CORD AND TELEPHONE LINE CORD FROM THE WALL. Then remove the telephone by the
unplugged cords.
About cordless telephones
• Privacy: The same features that make a cordless telephone convenient create some limitations.
Telephone calls are transmitted between the telephone base and the cordless handset by radio
waves, so there is a possibility that the cordless telephone conversations could be intercepted by radio
receiving equipment within range of the cordless handset. For this reason, you should not think of
cordless telephone conversations as being as private as those on corded telephones.
• Electrical power: The telephone base of this cordless telephone 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 cordless handset if the telephone base is unplugged, switched off or if the electrical power
is interrupted.
• Potential TV interference: Some cordless telephones operate at frequencies that may cause
interference to televisions and VCRs. To minimize or prevent such interference, do not place the
telephone base of the cordless telephone near or on top of a TV or VCR. If interference is experienced,
moving the cordless telephone farther away from the TV or VCR often reduces or eliminates
the interference.
