INTRODUCTION
GENERAL DESCRIPTION
This manual covers the BTR-300 Base Station and the TR-300 Portable Transceiver.
The RadioCom Models BTR-300 and TR-300 were specifically designed to provide the user with a highly flexible wireless two-way com- munication system with the capability to inter- face with a wired intercom system and other auxiliary audio.
At the BTR-300 operator’s command, the remotes may communicate with each other, with a wired intercom system or with an auxil- iary system. The BTR-300 Base Station with its one transmit and four receive channels is designed to operate in full duplex (simulta- neous two-way communications) with up to four TR-300 Belt Pack transceivers. See block diagram in Figure 1.
