RTS Model BTR-240
Base Station
The BTR-240 is powered via a 12 – 15 VDC
receptacle on the rear panel. A 12 VDC
power supply is supplied with the BTR-240.
The front panel LCD display and buttons
allow the following menus to be obtained:

(Preliminary Information)
General Description
The RTS model BTR-240 base station
transceiver is a rack mountable, full-duplex,
wireless intercom radio. The base station
provides a central relay location which
handles the audio traffic between the TR240 beltpacks.

The front panel also has an on/off power
control. A talk button, talk light, channel
select button, channel select lights, and
volume are also available for a user at the
base station local headset.
A BTR-240 base station can be used to
support up to eight full-duplex wireless TR240 beltpacks and many more for beltpacks
in push-to-transmit mode.
The BTR-240 uses the IEEE 802.11b
technology to transmit / receive within one
channel of the 1 – 11 (2.412 to 2.462 GHz)
allowable channels of the 2.4 GHz ISM
band. Operation of the BTR-240 is license
free.
The typical line-of-sight distances for the
system may be 300 feet.
The transmit and receive antennas are
connected via unique reverse TNC
connectors on the rear panel of the unit.

Operation
When the BTR-240 is turned on, the backlight
of the LCD and menu buttons will illuminate to
indicate power. The unit takes approximately
25 seconds to boot and its status is indicated
with a progress bar on the LCD.
After the unit has booted successfully, the Startup screen displays the unit model and software
versions for approximately 3 seconds.
The Status Screen is the main information
screen of the base station. It displays the current
status of the system including:
•
•
•
•
•
NOTE: The RF channel of operation setting is
remembered and the unit will continue to boot
on the same channel until it is set differently by
the user.
NOTE: The RF channel of operation needs to
be verified / set before turning on the TR-240
beltpacks. If a beltpack is already associated
with a base station, it may not continue to
associate once the channel is changed. If this
occurs, the beltpack will need to be rebooted.
1.1
Manual RF Channel Selection
To manually select an RF channel, navigate to
the “RF Channel” menu item and press the
 button.
RF Channel of operation
Association (how many full-duplex
beltpacks are associated with the base
station)
2W / 4W intercom settings
Auxiliary input / output settings
Speaker setting indicator
The current RF channel will be blinking
indicating that the channel is in “set” mode and
ready to be changed.
Once the Status Screen is displayed, it is ready
to act as an access point and TR-240 beltpacks
can be turned on. Once the TR-240 beltpacks
are on in “wireless” mode, they will associate
with the RF channel selected at the base station.
Setting the RF Channel
The RF channel can be changed by two different
methods:
•
•
Manual RF Channel Selection
ClearScan™
BTR-240 Users Manual - Preliminary
Rev D – 4 / 18 / 2011
Using the  and  buttons, the RF
channel is increased and decreased,
respectively.
Once the desired RF channel has been identified
and blinking, pressing the  button will
select it and save the settings. Once the channel
is set, the display will stop blinking and the user
can either press  again to re-enter “set”
mode and change it, or press  to go
back a menu screen.
After navigating back to the Status Screen, the
new current RF channel of operation is
indicated.
Page 4 of 8
NOTE: If the  button is pressed and
held for approximately half a second, the LCD
will abort any current changes if in “set” mode
and immediately return to the Status Screen.
1.2
ClearScan™
A user may also run a ClearScan™ from the
front panel to automatically select the most
available RF channel for use.
A ClearScan™ is performed from by pressing
the  +  buttons on the front panel
simultaneously for approximately 3 seconds.
2.1
Pressing the  button on the front panel
will enable and disable the audio path from the
headset microphone. The green talk light will
be illuminated when the microphone path is
enabled. The green talk light will be off when
the microphone path is disabled.
2.1.1
NOTE: The RF channel of operation needs to
be verified / set before turning on the TR-240
beltpacks. If a beltpack is already associated
with a base station, it may not continue to
associate once the channel is changed. If this
occurs, the beltpack will need to be rebooted.
Local Headset Configuration
There are several ways to configure the local
headset at the base station front panel. Settings
for the local headset include the following:
•
•
•
•
Talk Button
Channel Select Button
Local Headset Volume
Microphone and Sidetone Levels
BTR-240 Users Manual - Preliminary
Rev D – 4 / 18 / 2011
Latch
Tap the  button for less than ½ second
and the microphone path latch and remain
enabled. Tap the  button again to turn
off the latch and disable the microphone path.
2.2
After the operation has been performed, the
LCD returns to the Status Screen to indicate the
current RF channel of operation.
Momentary
Press and hold the  button for longer
than ½ second and the microphone path will be
enabled. The microphone path will be disabled
when the  button is released.
2.1.2
Once the ClearScan™ operation is initiated, the
scanning status is indicated by a progress bar on
the LCD.
Talk Button
Channel Select Button
Pressing the  button will select
the intercom channel for the local headset. Each
press of the button will cycle through the
options; Intercom 1, Intercom 2, both. The
green LEDs above the button will be
illuminated for which intercom channel is
currently active for the local headset.
2.3
Local Headset Volume
The local headset volume can be controlled
from the front panel by turning the 
knob clockwise and counterclockwise to
increase and decrease the volume, respectively.
2.4
Microphone and Sidetone Levels
The microphone gain and sidetone level can be
adjusted by navigating the menu on the LCD to
the “Local Headset” option and pressing the
 button.
Page 5 of 8
Once in the “Local Headset” menu option, the
“Mic Gain” and “Sidetone” levels are available
for adjustment.
Using the  and  buttons to
navigate the cursor to the desired level to
change. After pressing the  button, the
cursor and the level number will blink
indicating that the base station is in “set” mode.
Now, the  and  buttons can be
used to increase and decrease the levels,
respectively. Once the desired level is obtained,
the setting is selected and saved by pressing the
 button again.
Once the microphone gain or sidetone level is
set, the cursor and the level number will stop
blinking. At this time a user can press 
again to re-enter “set” mode and change levels,
press  or  to select a different
level for adjustment, or press  to go
back a menu screen.
