Unplug all electrical appliances when you know an electrical storm is approaching. Lightning can
pass through your household wiring and damage any device connected to it. This phone is no
exception.
Warning: Please do not attempt to unplug any appliance during an electrical storm.
Caution: Changes or modifications to this product not expressly approved by Uniden, or operation
of this product in any way other than as detailed by this Operating Guide, could void
your authority to operate this product.

Range

Your new phone is designed to achieve the maximum possible range by transmitting and receiving
according to the highest specifications set forth by the FCC. We have rated this phone to operate at
a maximum distance with the qualification that the range depends upon the environment in which
the telephone is used. Many factors limit range, and it would be impossible to include all the
variables in our rating. The Maximum Range rating of this phone is meant to be used as a means of
comparison against other range claims.

Telephone Line Problems

The FCC has granted the telephone company the right to disconnect service in the event that your
phone causes problems on the telephone line. Also, the telephone company may make changes in
facilities and services which may affect the operation of your unit. However, your telephone
company must give adequate notice in writing prior to such actions to allow you time for making
necessary arrangements to continue uninterrupted service.
If you are having trouble with your telephone service, you must first disconnect your phone to
determine if it is the cause of your problem. If you determine that it is the cause, you must leave it
disconnected until the trouble has been corrected.

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.

More Than One Cordless Telephone

If you want to use more than one cordless telephone in your home, they must operate on different
channels. Press the channel key to select a channel that provides the clearest communication.
