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.
