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 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 TL7912 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.
Encrypted for added security
The 64 bit encryption adds an extra layer of security between your TL7912 headset and TL7912 base to keep your conversations private.
