Plantronics CT14 User Manual page 35

The antenna(s) used for the base-unit must be installed to provide a separation distance of at least 20 cm
from all persons and must not be collocated or operated in conjunction with any other antenna or transmitter.
Radio interference may occasionally cause buzzing and humming in your cordless dial pad, or clicking
noises in the base. 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.
