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 against similarly equipped phones of the 
leading competition. 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 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.
HD audio
HD audio improves sound quality by expanding and rebuilding frequencies that are lost with 
traditional phone calls. There is no additional telephone service requirement to use HD audio.
It is designed to work with standard telephone service. Your system will automatically 
enhance all received sound with HD audio.
