Safety Instructions

•  Some electronic devices are susceptible to electromagnetic interference sent by devices that may not be adequately shielded. For best performance, position the Wireless Home Phone base as far from these types of devices (TV sets, radios and other automated office equipment) as possible (at least 8 feet) so as to avoid possible electromagnetic interference.

•  Do not use the device in hospitals.
