This is the corded, clarity-enhancing telephone that not only makes voices 40 dB louder by amplifying high-frequency sounds, but also reduces low-frequency noise that causes interference and distortion. Unlike lesser models that only adjust for volume or completely eliminate low-frequency sounds, it provides a full range of frequency adjustment for richness of sound. The phone has a message-waiting indicator with a solid red lamp that is easily distinguished, an incoming call indicator that causes the entire dial pad to flash red, and a 50-number memory. The unit is also call waiting and caller ID capable. The telephone has two one-touch emergency speed-dial buttons, headset jack, neckloop jack, integrated alarm clock, and an adjustable ringer that can reach 95 dB. Base: 2 1/4" H x 8" W x 8 1/2" D.
