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 headset base can communicate over
only a certain distance — which can vary with the locations of
the headset base and headset, the weather, and the construction
of your home or office.
Extended range and clarity
The TL7612 is a fully cordless DECT 6.0 headset offering a range
of up to 500 feet. Sound level protection technology conforms
to the current regulations and is used to filter out the loud and
high-pitched noises.
