Add Full Duplex Wireless to Your Existing Hard-Wired System!
Quickly and inexpensively add full duplex wireless headsets to a hard-wired system. Simply plug a TD 900 Master radio into your wired system and the corresponding remote is automatically added to the talking pattern. Wireless users can communicate simultaneously with the wired party line just as though they were plugged in. An interface cable for hookup to your wired system is included for each remote wireless that you wish to add.
No base stations needed! Up to 40 wireless users can be added!
