The Telex┬« RadioComÔäó BTR-700 UHF-synthesized wireless intercom system offers the ultimate in reliable, high performance, high fidelity full duplex communications. The BTR-700 system includes the BTR-700 frequency-agile base station, working with up to four TR-700 frequency-agile beltpacks. The BTR-700 base station provides full duplex communications with the beltpacks. The BTR-700 system is perfectly suited for stand-alone operation and can interface with Audiocom┬« (Telex┬«), RTS┬« TW, Clear-Com┬« as well as RTS┬« Matrix systems and other four-wire communications systems. In addition to the external intercom systems interfaces listed above, the system provides connections for auxiliary balanced audio input and output. The RadioComÔäó BTR series has been designed for reliable, efficient operation. Operating in the 518 to 868 MHz range, the units operate reliably at line-of-sight distances of 1,000 feet. With available antenna systems from Telex┬«, the effective operating range can be extended. The high efficiency beltpacks provide 12-14 hours of uninterrupted operation using standard alkaline batteries.
