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. Open range test was performed by Wyle Laboratories,
an independent commercial test facility. “Up to 500 feet” cordless
headset range refers to the maximum open field range. Actual range
may vary depending on intervening obstacles.
Sound level protection technology conforms to the current regulations
and is used to filter out the loud and high-pitched noises.
