900 MHz cordless phones outperform traditional, lower frequency models in both sound quality and range potential. A 900 MHz radio wave bounces off objects more efficiently, and, as a result, will carry a greater distance. In addition, the 900 MHz high frequency wave holds up better than lower frequency phones to sources of interference, such as fluorescent lighting.
The Clarity C435, featuring Clarity® Power™ technology, makes telephone conversations not only louder, but also clearer and easier to understand. With up to 30 decibels of amplification, the C435 is an ideal solution for those with a mild-to-moderate hearing loss.
