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.
