DECT 6.0 digital technology

Digital Enhanced Cordless Telecommunications (DECT) 6.0 is a new frequency band that transmits your voice across multiple channels. This technology provides superior quality of voice and sound, high protection against wiretapping and better range than 2.4 GHz and 5.8 GHz phone systems, while not interfering with wireless routers.

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

Experience the best in long-range coverage and clarity, provided by a unique antenna design and advances in noise-filtering technology. The TL7600 is a fully cordless DECT 6.0 headset offering a range of up to 500 feet. Open range test was performed by Wyle Laboratories, an independent commercial test facility. “Up to 500 feet” cordless headset range refers to the maximum open field range. Actual range may vary depending on intervening obstacles.

Sound level protection technology conforms to the current regulations and is used to filter out the loud and high-pitched noises.
