Panasonic KX-TG4022N 1.9 GHz Digital DECT 6.0 2X Handsets Cordless Phone Integrated Answering Machine

Dect 6.0 PLUS
Dect Plus technology takes the superb sound quality and outstanding range of DECT 6.0 phones to a whole new level. By increasing the frequency of error correction up to 80x, the transmission quality is improved and the phone's range is extended. Engineered to work in 1.9GHz frequency, our DECT 6.0 phones won't conflict with common wireless devices such as 2.4GHz routers, wireless keyboards and mice, microwave ovens and other household items. And because it's digital, you'll enjoy long range and clear sound while deterring eavesdropping.

Intelligent Eco Mode
This clever new feature automatically lowers 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 good for the environment. When less power is used by the handset to communicate with the base unit, battery life is prolonged which results in less frequent charging and can result in fewer batteries in landfills.
