If you’re looking for superb sound quality and long range, look no further than the KX-TG4222N DECT 6.0 Plus technology in Panasonic cordless phones. Thanks to error correction up to 80x, you get clear transmission even with extended range. Engineered to work in 1.9GHz frequency, our DECT 6.0 Plus phones won't interfere with wireless devices such as routers, wireless keyboards and microwave ovens. Whether you use them in the basement or the backyard, our phones truly go the distance. With the All-Digital Answering System, recording, saving and retrieving your messages has never been easier. Your messages are recorded on an advanced microchip for quiet operation and easy retrieval. Total recording time is approximately 18 minutes. With the Intelligent Eco Mode, when you use the handset closest to the base unit, you’ll automatically lower power consumption. This not only extends available talk time but also prolongs battery life. Which means less frequent charging and in the end, fewer batteries in landfills.
