Telephone operating range

This cordless telephone operates with the maximum power allowed by the Federal Communications Commission (FCC). Even so, the handset(s) and tele- phone base can communicate over only a certain distance - which can vary with the locations of the telephone base and handset(s), the weather, the lay- out, and the construction of your home or office.

2.4 GHz digital spread spectrum frequency hopping technology

The technology digitally transmits your voice across multiple channels in 2.4GHz frequencies to provide enhanced range, ultimate sound clarity and advanced privacy against eavesdropping on your calls, while not interfering with wireless routers.
