Telex Model BTR-700 Base Station
Owners/Users Manual (Preliminary Information)
General Description
The Telex Model BTR-700 is a part of the RadioCom ™ wireless intercom
series providing all of the Base Station functions.
The BTR-700 Base Station is a four channel receive and a one channel
transmit unit operating within the 518-608 and 614-746 MHz range (TV
Channels 22 to 59). Each base transmitter operates on selected frequencies
in the lower half of the frequency range and the receivers operate on selected
frequencies in the upper half of the frequency range.
The transmit frequency is used to transmit voice and signals to all four
of the TR-700 portable (beltworn) units.
Each of the base station receive frequencies are used to receive
transmissions from each portable unit. Full Duplex (telephone type)
operation is used and any portable can talk to any other portable or, any or
all of the base receivers can be deselected allowing the mobiles to monitor
only. Independent receive channels can be enabled or disabled by front panel
pushbuttons. The presence or absence of a portable transmit is displayed on
the LCD Display.
Two independent 2 wire or 4 wire intercom units can be connected to the
base station. Each intercom has independent input and output level
adjustments.
An Auxiliary connector is provided for general audio use and also has input
and output level controls.
A local headset connector is provided with volume, microphone gain control
and a talk/mute switch.
A front panel readout on the base station indicates the frequency or channel
that is in current use. A separate menu is used to select one of several
pre-programmed frequency sets or each base can be programmed to special
frequencies by the user.

The BTR-700 has a built-in 100 to 240 VAC 50/60 Hz power supply.
Power is controlled by the ON/OFF front panel switch.
Half (1/2) Wave antennas are supplied with the base station.
These antennas are ground independent.
Transmit (RF) power is switchable on the rear panel from 50mW
(maximum) to 5 mW (minimum). The transmit power can also be turned off
for use where several bases are required that only use one transmit
frequency. The low power setting can be useful where multi-system
intermod could occur or when it is desired to reduce the base transmitter
range.
An Intercom (I/C) termination switch on the rear panel allows selecting
Telex, RTS or ClearCom connections.
The Intercom has XLR and RJ Connectors on the rear panel in order to
“Loop-Thru” to inter-connect several bases together.
The Auxilliary Audio Input and Output connectors are “one way” ports
that are useful for stand-alone applications.

both) from the front panel. The input and output levels are independently
adjustable from the front panel. An Auxiliary XLR Input and XLR Output is
also available.
Local Headset:
A 4 wire XLR connector is located on the front panel with Headset Volume,
Microphone Gain Control, and Press to Talk/Lock to Talk switch.

Mandatory Safety Instructions
to Base Station Installers and Users
1. Use only manufacturer or dealer supplied antenna. Antenna minimum
safe distance, as calculated from FCC requirements, is 4.8cm.
However, the FCC default for the minimum safe distance is 20cm.
Antenna gain: zero dBd referenced to a dipole.
2. The FEDERAL COMMUNICATIONS COMMISSION has adopted a safety
standard for human exposure to RF (Radio Frequency) energy, which is
below the OSHA (Occupational Safety and Health Act limits.
3. To comply with current FCC RF Exposure limits, the antenna must be
installed at or exceeding the minimum safe distance show here, and in
accordance with the requirements of the antenna manufacturer or supplier.
4. Antenna substitution: Do Not substitute any antenna for the one
supplied by or recommended by the manufacturer or radio dealer.
You may be exposing person or persons to harmful radio frequency
radiation. You may contact your radio dealer or the manufacturer for
further instructions.
5. WARNING: Maintain a separation distance from the antenna to
person(s) of at least 20cm.
You, as the qualified end-user of this radio device must control the
exposure conditions of bystanders to ensure that the minimum
separation distance (above) is maintained between the antenna and
nearby persons for satisfying RF Exposure compliance.
The operation of this transmitter must satisfy the requirements of the
General Population/Uncontrolled Exposure Environment for workrelated use. Transmit only when person(s) are at least the minimum
distance from the properly installed, externally mounted antenna.
