This cordless telephone set earned The Best rating from the Hammacher Schlemmer Institute because it produced the clearest conversations and had the greatest range. The Best Cordless Phone provided crystal clear conversations by reducing background noise and amplifying voices, unlike lesser models that experienced static and echoing during calls. The long-range cordless phones use DECT 6.0 technology to maintain a reliable connection up to 248' away from the base station, far superior to other models that lose the signal at only 184'. The unit‘s quick set-up guide and detailed, easy-to-follow instruction booklet made this cordless phone set the easiest to set up and each handset’s backlit LED display and large buttons enabled simple dialing. It has a battery back-up feature that maintains calling functions during a power outage, a built-in answering machine, and audible caller ID (subscription required). The base unit supports up to six handsets (four included) and can be wall mounted. 7" W x 6 1/2" H x 4 1/2" D. (15 oz.)
