The Eartec UL4D UltraLITE 4-Person System comes with 4 double headsets. These UltraLITE double headsets let users stay in constant full-duplex voice contact while on the move. Unlike most wireless headsets, they work without belt pack transceivers. All electronics, including the battery, are inside the ear cups. The headsets feature deluxe padding and a fully adjustable noise-canceling microphone, ensuring effective voice communication even in noisy environments. Key features include a self-contained 'all-in-one' design that gets rid of wires or belt-worn radios, the ability to wear on either the left or right ear with a 270-degree swiveling mic boom, DECT technology for digital enhanced cordless telecommunications, lithium polymer batteries that offer 6 hours of continuous operation, and no need for FCC licensing - it's ready to use right out of the box. Technical specifications include a DECT 6.0 standard, frequencies of 1920 - 1930MHz in the USA and 1880 - 1900MHz in Europe, a weight of 4 oz, and more.
Using the Eartec UL4D UltraLITE 4-Person System is easy. First, make sure the headsets are fully charged. You can wear the headset on either your left or right ear and adjust the mic boom to your preferred position. Once you turn it on, you'll be able to stay in full-duplex voice contact with others in the system. In high - noise environments, the noise - canceling microphone will help keep your voice clear. When it comes to charging, use the provided charger and plug it into a suitable power source. The charging time is about 3 hours, and you'll get 6 hours of operation. Store the headsets in a place where the temperature is between - 10°C and 60°C, and use them in a normal temperature range of 0°C to 10°C. To keep the headsets in good condition, clean them regularly with a soft cloth. Avoid getting them wet or exposing them to extreme heat or cold.
