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