Radio Interference; More Than One Cordless Telephone - Uniden XC645 User Manual

Radio Interference

Radio interference may occasionally cause buzzing and humming in your
cordless Handset, or clicking noises in the Base Unit. This interference is
caused by external sources such as TV, refrigerator, vacuum cleaner,
fluorescent lighting, or electrical storm. Your unit is NOT DEFECTIVE. If
these noises continue and are too distracting, please check around your
home to see what appliances may be causing the problem. In addition, we
recommend that the Base not be plugged into a circuit that also powers a
major appliance because of the potential for interference. Be certain that the
antenna on the unit is fully extended when needed.
In the unlikely event that you consistently hear other voices or distracting
transmissions on your phone, you may be receiving radio signals from
another cordless telephone or other source of interference. If you cannot
eliminate this type of interference, you need to change to a different channel.
Finally, it should be noted that some cordless telephones operate at
frequencies that may cause interference to nearby TVs and VCRs. To
minimize or prevent such interference, the base of the cordless telephone
should not be placed near or on top of a TV or VCR. If interference is
experienced, moving the cordless telephone farther away from the TV or
VCR will often reduce or eliminate the interference.
