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 unit is no exception.
Warning: Please do not attempt to unplug any appliance during an

electrical storm.

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.
This unit is designed to achieve the maximum possible range by transmitting and receiving according to the highest specifications set forth by the I.C. 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 your integrated telephone answering device 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 storms. 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 Unit 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; and, 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 XCA4500, there are some important guidelines you should consider: The location should be close to both a phone jack and continuous power outlet. (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 integrated telephone answering device on the wall, make sure to change the handset retainer so that the tab which holds the Handset faces up. (See page 20 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
The XCA4500 requires a standard electrical outlet (120 volts AC without a switch to interrupt power) and the included AC adapter. Connect the adapter as shown below. 1. Wrap the power cord around the convenient notch on the bottom.

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.
2. When power is first applied, the Message Counter LED display flashes P quickly while the systems memory initializes. When the flashing slows, press the STOP button on the Base Unit. The Message Counter LED display turns off, and the time and remaining message record time are announced.

Charging the Handset Battery Pack
Initial Battery Charging The rechargeable Nickel-Cadmium battery pack must be fully charged before using your phone for the first time. We recommend that the battery pack charge for approximately 15-20 hours, without interruption, before plugging the phone line into your new phone. 1. Place the Handset on the Base Unit. Depending on your installation, you can charge the Handset in the upright position.
You can charge the Handset in its facedown position.

Continuous Battery Charging For the best battery performance, return the Handset to the Base Unit at the end of the day to keep the battery fully charged.

Low Battery Indicator

When the Battery Pack in the Handset is very low and needs to be charged, the TALK/BATT LOW LED flashes.
If the TALK/BATT LOW LED begins to flash, the phone is programmed to eliminate its functions to save power. The table below describes what to do to return your phone to normal operation. During a Call Only the T button operates. The Handset beeps and the TALK/BATT LOW LED flashes once every three seconds. Complete your call as quickly as possible. Return the Handset to the Base Unit for charging. In Standby Mode None of the buttons will operate. The Handset TALK/BATT LOW LED flashes once every three seconds. You will not be able to make a call. Return the Handset to the Base Unit for charging.

Allow 15 to 20 hours without interruption for the Handset to fully recharge.
Setting the Pulse/Tone Switch
Be sure the PULSE/TONE switch is in the TONE position if you have touch-tone telephone service.

Automatic Digital Code Security
Many cordless telephones operate similarly and on the same frequency. Without digital code security, another Handset could make calls using your Base Unit and telephone line. To avoid unauthorized calls on your phone, a Digital Code feature was added to the XCA4500. This Digital Code is shared only between the Handset and Base Unit. The Code is set automatically when you first use the phone. To reset the Digital Code, be sure the Handset is on the Base, then: 1. Press INTERCOM on the Base Unit.
Remove the Handset from the Base Unit, and then set it down again.
The CHARGE LED will blink to indicate that the Digital Security Code is set to one of more than 65,000 codes.
If the Base Unit loses power while the Handset is off the Base, the Digital Code may be erased. When this happens, the Handset will not function. To establish communication between the Handset and Base Unit: 1. Restore power to the Base Unit, and place the Handset back on the Base Unit.
The CHARGE LED will blink to indicate that the Digital Security Code is set.
