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 perform up to 45% better in
range competitions. Now calls can be taken in the basement, backyard and garage with exceptional
sound quality.

Telephone operating range

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

Redefining long range coverage and clarity

This telephone base comes with an antenna which gives much better clarity and covers a longer
range than before.
