Unlike lesser telephones with hard-to-read caller ID displays, these have a large display and an audible feature that announces the names of each caller. A built-in equalizer lets you adjust the phone’s HD audio to best suit your hearing, while flashing LEDs visually alert users to incoming calls and new voice messages. The oversized buttons are backlit, and a large LCD with numbers 1 1/2 times larger than standard telephones clearly shows the name and number of incoming calls (base and handset). The base and telephone each have a 50-number memory and in the event of power failure, the base will retain emergency and speed dialing functions, while allowing incoming and outgoing calls. Operating on the 1.9 GHz DECT band, this phone’s unique antenna design and advanced noise filtering provides unsurpassed range and clarity without interference. Compatible with all inductive coupled hearing aids. Caller ID and voicemail require subscription with telephone company. Includes corded telephone base and one cordless telephone. Supports up to 12 cordless handsets, available below. Base: 3 3/4" H x 8" W x 8 1/2" D. (2 lbs.) Cordless telephone: 7 1/2" H x 3 3/4" x 3" D. (8 oz.)
