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