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 
telephonebaseandhandset,theweather,andtheconstructionofyourhomeoroce.
Redening 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.
Simulated full-duplex handset and base speakerphones
The simulated full-duplex speakerphones on your handset and telephone base allow 
both ends of a call to speak and be heard at the same time. Optimal performance is 
subject to external factors and individual usage.
