Telex RadioCom BTR-500/600C - Manual (Page 4)

Introduction
General Description
The Telex Radiocom BTR-500 and BTR-600C
UHF Wireless intercom systems offer the ultimate
in reliable, high performance, high fidelity full du-
plex communications.
The BTR-500 series includes the BTR-500 fre-
quency agile base station, working with the TR-500
transceiver beltpack. The BTR-500 base station pro-
vides full duplex communications with a single
beltpack. Sixteen BTR-500s, or more, may be oper-
ated simultaneously. Also a single BTR-500 base
station can accommodate an unlimited number of
beltpacks operating in “Push-to-Transmit” mode.
The BTR-600C series has all the features of the
BTR-500 with the addition of digital modulation
and encryption for secure communications. Base
station and beltpacks can choose from over 65,000
user selectable security codes out of over 16 million
possible codes by means of four cipher code
switches on the units. Sixteen BTR-600C, or more,
may be operated simultaneously, permitting 16, or
more, discrete full duplex radio channels.
The BTR systems incorporate auto-switching 2
channel operation, permitting the beltpack operator
to choose between 2 separate audio channels of
communications, with the base station tracking the
beltpack selection. Auto-switching allows the user
the flexibility to create a party-line and a private
line within the same beltpack.
The BTR-500 and BTR-600C systems are perfectly
suited for stand-alone operation and also can inter-
face with Audiocom® (Telex), RTS® TW, as well
as RTS Matrix systems and other 4 wire communi-
cations systems. Clear-Com® intercom system may
also be interfaced to a BTR-500 and BTR-600C
systems through the use of a Telex to Clear-Com In-
terface box, see “Accesories” for more information.
In addition to the external intercom systems inter-
faces listed above, the base stations provide connec-
tions for auxiliary balanced audio input and output.
The Radiocom BTR series has been designed for re-
liable, efficient operation. Operating in the 520 to
760 MHz range, the units operate reliable at dis-
tances of 1,000 feet. With available antenna systems
from Telex, the effective operating range can be ex-
tended. The high efficiency beltpacks provide 12
hours of uninterrupted operation using standard al-
kaline batteries.
