This digital phone lets you hear who's calling from across the room without having to get up. Using text-to-speech technology, the talking Caller ID announces caller's information in between rings. Or use the large 1.8" LCD screen to see who's calling at a glance. Whether you're at home or on the road, the advanced TAD functions will automatically send a message to a registered cell or office phone along with playback options. Enhanced Noise Reduction suppresses background noise around the caller while simultaneously enhancing their voice for easier communication. A powerful battery backup system keeps you connected even when the power goes out. Keep a charged handset in the base unit, and you can still make and receive calls with the other cordless handsets. This phone is designed to automatically lower the power consumption when you're using the handset close to the base unit. Not only does it extend the available talk time, it's great for the environment.
