By increasing the frequency of error correction, the transmission quality is improved and the phone's range is extended. Engineered to work in 1.9 GHz frequency, their DECT 6.0 phones won't conflict with common wireless devices such as 2.4 GHz routers, wireless keyboards and mice, microwave ovens and other household items.

Panasonic KX TG7644M features 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 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.
