Telex TR-1, BTR-1 User Manual

BTR-1 & TR-1
UHF-Synthesized Digitally Encrypted Wireless Intercom System
The Telex RadioCom BTR-1 UHF wireless intercom system is the ultimate in reliable, high performance, encrypted full duplex communications. The BTR-1 system includes the BTR-1 frequency-agile base station and a TR-1 frequency-agile beltpack. The BTR-1 system provides full duplex, encrypted digital communication. The base station provides the beltpack with access to a six-intercom port matrix of two-wire systems or communication to a four-wire intercom system. The system can interface with Telex Audiocom, RTS Two-Wire Intercom, Clear-Com two-wire intercom systems as well as four-wire communication systems. In addition to the two- and four-wire intercom systems the base station provides connections for auxiliary balanced audio input and output, as well as relay closure and the ability to use one of the six intercom lines as a wireless only communication intercom. The system is
also perfectly suited for stand-alone operation. The BTR-1 has been designed for reliable, efcient operation. Operating in the 482 to 746 MHz range. The unit has expansion ability to add dozens of base stations to create a system. The high-efciency
