Telephone operating range

This cordless telephone operates with the maximum power allowed by the Federal Communications Commission (FCC). Even so, the handset(s) and telephone base can communicate over only a certain distance - which can vary with the locations of the telephone base and handset(s), the weather, the layout, 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 2.4 GHz frequencies to provide enhanced range, ultimate sound clarity and advanced priva- cy against eavesdropping on your calls, while not interfering with wireless routers.
