Digital Wireless Intercom System

Standard System

The Digital Wireless Intercom System is an intercom system for broadcasting, theater, hall, and industry, which utilizes the basic technique of the personal handy phone (PHS), developed as a digital mobile communication technique of the “second generation” cordless telephone system. The coexistence of the simple operability that has most preferentially taken into consideration the basic functions as a wireless intercom and the reliability as professional equipment that has sought the ultimate in what is required therefor based on the achievements cultivated in developing the analog wireless intercom. Further, the radio communication device has fully incorporated the characteristics, such as clear sound quality inherent in digital communication, use of abundant and stable channels, excellent extendibility, etc.
