Operating range
This cordless headset operates within the maximum power
allowed by the Federal Communications Commission (FCC). Even
so, this headset and headset base can communicate over only
a certain distance — which can vary with the locations of the
headset base and headset, the weather, and the construction of
your home or office.
Extended range and clarity
The TL7610/TL7611 are fully cordless DECT 6.0 headsets offering
a range of up to 500 ft. Sound level protection technology
conforms to the current regulations and is used to filter out the
loud and high-pitched noises.
