Radio InterferenceRadio 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 a TV, refrigerator, vacuum cleaner, fluorescent lighting, computer
equipment, or electrical storm. Your unit is NOT DEFECTIVE. If these noises con-
tinue and are too distracting, please check your office to see what appliances may be
causing the problem. In addition, we recommend that the base unit not be plugged
into a circuit that also powers a major appliance because of the potential for interfer-
ence.
In the unlikely event that you consistently hear other voices or distracting transmis-
sions on your phone, you may be receiving radio signals from another cordless tele-
phone or some other source of interference. If you cannot eliminate this type of
interference, change to a different channel.
