5.8 GHz digital spread spectrum frequency hopping technology
This technology digitally transmits your voice across multiple channels in
both the 5.8GHz and 2.4GHz frequencies to provide enhanced range, ultimate
sound clarity and advanced privacy against eavesdropping on your calls,
while not interfering with wireless routers.
Telephone operating range
This cordless telephone operates within the maximum power allowed by
the Federal Communications Commission (FCC). Even so, this 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, and
the construction of your home or office.
