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.
