GETTING STARTED

Setting up the Phone

Do the following steps: A. Choose the best location. B. Install the rechargeable battery pack into the handset. C. Connect the base unit. D. Choose the dialing mode.
If your home has specially wired alarm equipment connected to the telephone line, be sure that installing the system does not disable your alarm equipment. If you have questions about what will disable alarm equipment, contact your telephone company or a qualified installer.

Even when the battery pack is not being used, it will gradually discharge over a long period of time. For optimum performance, be sure to return the handset to the base unit after a telephone call. Standby Mode The handset is not in use and talk/flash has not been pressed. Talk Mode The handset is not in the cradle and talk/ flash or speaker has been pressed enabling a dial tone. Ta l k appears on the display.
Cleaning the battery charging contacts
To maintain a good charge, it is important to clean the charging contacts on both the handset and the base unit once a month. Using water only, dampen a cloth to clean the charging contacts. Then make sure to go back over the charging contacts with a dry cloth before returning the handset to the base to charge. Caution: Do not use paint thinner, benzene, alcohol, or other chemical products. Doing so may discolor the surface of the telephone and damage the finish.

GETTING STARTED [13]

C. Connect the base unit
Use only the supplied [AD-800] AC adapter. Do not use any other AC adapter. Place the power cord so that it does not create a trip hazard or where it could become chafed and create a fire or electrical hazard.
1) Connect the AC adapter to the DC IN 9V jack and to a standard 120V AC wall outlet.
2) Set the base on a desk or tabletop, and place the handset in the base unit. 3) Make sure that the charge LED illuminates. If the LED does not illuminate, check to see that the AC adapter is plugged in and the handset makes good contact with the base charging contacts.
Connect the AC adapter to a continuous power supply. Place the base unit close to the AC outlet so that you can unplug the AC adapter easily.
After installing the battery pack in the handset, charge your handset at least 15-20 hours before plugging into the phone line. 4) Once the handset battery pack is fully charged, connect the telephone line cord to the TEL LINE jack and to a telephone outlet. If your telephone outlet isn't modular, contact your telephone company for assistance.

Make a trial call. If the call connects, leave the setting as is, otherwise set the unit to pulse dialing. If your phone system requires pulse dialing and you need to send DTMF tones in certain situations during a call, you may Switch Over to tone dialing (refer to Tone Dialing Switch-over on page 32).

Radio Interference

Radio interference may occasionally cause buzzing and humming in your cordless handset, or clicking noises in the base. 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.

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. Hardwired 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.
