Product description

• COMSTAR Com-Center Full Duplex Wireless Base Station The COMSTAR Com-Center Full Duplex Wireless Base Station from Eartec is a fully-functional wireless base station that offers full duplex communication for up to 8 wireless headsets. The Com-Center has a simple design that does not require the use of beltpacks, allowing you to create a wireless network of 8 users who can all communicate simultaneously with no delay or voice activation, ideal for applications where teams need full use of their hands. You can even split users into 2 groups of 4 people, or bring everyone together in conference mode.
  
  The Com-Center connects wirelessly to headsets at distances of up to 400 yards in any direction, allowing 2 headsets to be up to 800 yards apart while still enjoying full communication capabilities. The Com-Center is self tuning, so no remote antenna is needed. The base station has a rechargeable NiMH battery that provides up to 6 hours of operation and can be changed in seconds. An AC wall plug and a battery sled for disposable AA batteries are also provided to give you additional powering options.
  
  The base station and other COMSTAR components work in the 1900MHz frequency band, which is reserved by the FCC for "PCS" voice communication, so no license is required. The system is certified for use in the USA, Canada, Europe, and Australia. Note: This item includes 1 base station. Headsets are sold separately.
