DECT 6.0 digital technology

The AT&T DECT 6.0 products offer unsurpassed range performance and sound clarity. This is achieved through a unique antenna design and advances in noise-filtering technology. An independent laboratory has confirmed that AT&T DECT 6.0 products outperform the range claims of other headsets. Now calls can be taken in the basement, backyard and garage with exceptional sound quality.

Operating range

This cordless headset operates within the maximum power allowed by the Federal Communications Commission (FCC). Even so, this headset and its base can communicate over only a certain distance, which can vary with the locations of the headset and its base, the weather, and the construction of your home or office.

Extended range and clarity

The TL7700 is a fully cordless DECT 6.0 headset offering a range of up to 500 ft. Sound level protection technology conforms to the current regulations and is used to filter out the loud and high-pitched noises.
