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, computer
equipment, or electrical storm. Your unit is NOT DEFECTIVE. If these noises con-
tinue and are too distracting, please check around your office 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 interfer-
ence. 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 transmis-
sions on your endpoint, you may be receiving radio signals from another cordless
telephone or other source of interference. If you cannot eliminate this type of interfer-
ence, 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 inter-
ference, 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.
More Than One Cordless Telephone
If you want to use more than one cordless telephone in your office, they must operate
on different channels. Press the channel button to select a channel that provides the
clearest communication.
Privacy
Cordless endpoints are radio devices. Communications between the Handset and Base
Unit of your cordless telephone are accomplished by means of radio waves which are
broadcast over the open airways. Because of the inherent physical properties of radio
waves, your communications can be received by radio receiving devices other than
your own cordless telephone unit. Consequently, any communications using your
cordless telephone may not be private.
Base Units and Handsets
The Handsets are programmed to work a specific Base Unit. You cannot switch to a
new Handset or a new Base Unit without having it reprogrammed by Inter-Tel.
