Expandable digital cordless answering system simplifies the way you make and take calls. Power backup operation lets you make and receive phone calls with the cordless handsets in case of a power outage. Large LED light atop the handset lets you know when someone calls - perfect for when you can't hear the ringer. Talking Caller ID announces caller ID information in between rings so you don't even have to look at the phone. Easy-to-read, extra-wide LCD lets you see who's calling at a glance. Bigger buttons make dialing a breeze while an amplified handset volume ensures you catch every word, even when there's background noise. DECT Plus technology takes the superb sound quality and outstanding range of DECT 6.0 phones to a whole new level. Engineered to work in 1.9GHz frequency, the phone won't conflict with common wireless devices. Digital design deters eavesdropping. Phone system includes one corded handset on base and one cordless handset with a charger. Base includes a dial keypad.
