Important Electrical Considerations
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.
6
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.

Installation
Selecting a Location
Before choosing a location for your new phone, there are some important
guidelines you should consider:
• The location should be close to both a phone jack and continuous
power outlet.
Note: A continuous power outlet is an AC outlet which does not
have a switch to interrupt its power.
• Keep the Base Unit and Handset away from sources of electrical
noise such as motors or fluorescent lighting.
• Be sure there is sufficient space to fully extend the Base Unit
antenna.
• The Base Unit can be placed on a desk or tabletop or mounted on a
standard AT&T or GTE wall plate.
• If you decide to mount your phone on the wall, make sure to change
the Handset Retainer so that the tab which holds the Handset faces
up. (See page 18 for more information.)
• You should charge your new phone for 15-20 hours before
completing the installation or using the Handset.
Telephone Line Outlets
There are two types of phone outlets:
Modular Jack
Most phone equipment available now uses modular jacks. Phone
cords are fitted with a molded plastic connector which plugs into
this type of jack. If you do not have modular phone jacks, contact
your local telephone company for information about their
installation.
Hard-wired Jack
Some equipment is wired directly to a phone jack, and these types
of installations require a modular jack converter. This type of
installation is not difficult; however, you should contact your Uniden
telephone dealer or a telephone supply store for advice about the
proper adapter or converter for your particular situation.

Connecting the Telephone Cords
Consider these safety guidelines before connecting the telephone cords:
CAUTION:
• Never install telephone wiring during a lightning storm.
• Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected.
• Use caution when installing or modifying telephone lines.
Applying Power to the Base Unit
All the
XC645
phones require an AC outlet, without a switch to interrupt
power, and the included AC Adapter. To relieve strain on the DC plug when
the phone is placed on a desk or table, connect the adapter as shown below.

Wrap the power cord around the

Important: Place the power cord so that it does not create a trip hazard, or
where it could become chafed and create a fire or other
electrical hazards.

Adapter Safety Feature
The AC Adapter furnished with this phone may be equipped with a polarized
line plug — a plug having one blade wider than the other. This plug will fit
into the power outlet only one way. If you are unable to insert the plug fully
into the outlet, try reversing the plug.
Do not alter the shape of the
blades of the polarized plug.

Direct Wall Mounting
If you do not have a standard wall plate, you can mount your phone directly
on a wall. Before mounting your phone, consider the following:
• Select a location away from electrical cables, pipes, or other items
behind the mounting location that could cause a hazard when
inserting screws into the wall.
• Make sure the wall material is capable of supporting the weight of
the Base Unit and Handset.
• Use #10 screws with anchoring devices suitable for the wall
material where the Base Unit will be placed.
