This series features include AutoTalk and AutoStandby. AutoTalk allows you to answer a call by just removing the handset from the cradle so you don't have to waste time pushing buttons. AutoStandby allows you to hang up by simply returning the handset to the cradle. To protect you against mis-billed calls, which might result from your phone being activated by other equipment, this series has Random Code digital security, which automatically selects one of over approx. 130,000 digital security codes for the handset and base. Frequency Hopping Spread Spectrum (FHSS) technology improves calling range and clarity, and eliminates cross talk. Because it rapidly changes transmission frequencies within the 2.4GHz bandwidth, this cordless phone helps reduce the possibility of eavesdropping. DirectLink mode is used when you have 2 or more handsets. You can use your handsets as transceivers.

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. (A continuous power outlet is an AC outlet which does not have a switch to interrupt its power.) Keep the base 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 antenna. The base can be placed on a desk or tabletop or mounted on a standard telephone wall plate. You should charge your new phone for 15-20 hours before completing the installation or using the handset.

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.
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.
