RTS Model TR-240 Beltpack
Owners / Users Manual
(Preliminary Information)
General Description
The RTS model TR-240 beltpack
transceiver is intended for use as a wireless
full-duplex intercom radio to be worn on a
belt. Multiple TR-240 beltpacks can be used
with a BTR-240 base station transceiver or a
BTR-24 access point to communicate with
each other over-the-air.
The TR-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. Its operation is license free.
The typical line-of-sight distances for the
system may be 300 feet.
The transmit and receive antennas are
internal to the beltpack so the unit has a
smaller profile. The outer case also provides
extra protection against possible damage to
the antennas.
The TR-240 is powered via an internal Li-
Ion battery that will provide up to 8 hours of
run time at room temperature.
The top panel provides on/off/volume
control, channel select buttons and lights,
talk button and battery status light.

Operation
Once a BTR-240 or BTR-24 is running, the TR-
240 may be switched on at anytime. The TR-
240 has key features that can be set during boot
and after the unit has booted. These settings
include the following:
• Mode of Operation
• Local Headset Configuration
1 Setting the Beltpack Mode
The TR-240 has three different and selectable
modes of operation: “wireless” mode, “wired”
mode, and “master wireless” mode. The normal
mode is “wireless”.
A TR-240 beltpack is configured to boot in one
of these modes by holding a specific button
sequence while the unit is booting.
NOTE: Once the TR-240 mode is set, it will
continue to boot in that mode until different
mode is selected on startup.
1.1 “Wireless” (Normal) Mode
In this configuration, a base station or access
point provides wireless coverage over the area
in which the beltpacks will be used.
1. Ensure that a BTR-240 base station or
BTR-24 access point is configured and
running the in the desired coverage area
of use.
2. Turn on the TR-240. The battery light
will turn green immediately indicating
power.
3. To place the TR-240 in “wireless” mode,
if not already set, press and hold the
<Talk> button as the beltpack boots.
4. After 20 seconds boot time, a voice
prompt “wireless” will be heard in the
headphone and the “Channel 1” button
light will activate indicating the unit is
running.
5. Release the <Talk> button if it is being
pressed.
6. Use as normal.
NOTE: In “wireless” mode, the wired Ethernet
port is disabled.
1.2 “Wired” Mode
Beltpacks are directly connected to each other
via an Ethernet cable or through a building’s
Ethernet infrastructure. In “wired” mode, the
wireless transmitter is disabled.
1. Connect the TR-240 to an existing wired
network or computer using a standard
Ethernet cable.
2. Turn on the beltpack. The battery light
will turn green immediately indicating
power.
3. To place the TR-240 in “wired” mode, if
not already set, press and hold the <2>
(blue) button as the beltpack boots.
4. After 20 seconds boot time, a voice
prompt “wired” will be heard in the
headphone, followed by the current
software version.
5. Release the <2> button if it is being
pressed.
6. Use as normal.
NOTE: In “wired” mode, the wireless
transmitter is disabled.
1.3 “Master Wireless” Mode
A beltpack can be configured to act as a base
station and eliminate the need to have an actual
BTR-240 base station or BTR-24 access point.
This “master” beltpack may still be used for
audio just as a normal beltpack. In “master
wireless” mode, the wired Ethernet port is
disabled.

Rev D – 3 / 09 / 2011
1. Turn on the TR-240. The battery light
will turn green immediately indicating
power.
2. To place the TR-240 in “master
wireless” mode, if not already set, press
and hold the <1> (green) button as the
beltpack boots.
3. After 20 seconds boot time, a voice
prompt “master wireless” will be heard
in the headphone, followed by the
current RF channel (“channel xx”) of
operation.
4. Release the <1> button after the voice
prompt indicates the RF channel.
5. Use as normal.
NOTE: In “master wireless” mode, the wired
Ethernet port is disabled.
1.3.1 Setting the RF Channel
For a beltpack that is in “master wireless” mode,
the RF channel of operation can be selected.
1. Boot the TR-240 in “master wireless”
mode by holding the <1> (green) button
as the beltpack boots.
2. Once the TR-240 has successfully
booted, the unit will give voice prompts
indicating “master wireless” and
“channel xx”.
3. To change the RF channel of operation,
continue to press the <1> button after the
RF channel has been indicated by the
voice prompt. Another voice prompt
“RF Selection” will be heard to notify
the user that the RF channel can now be
changed.
4. After the “RF Selection” voice prompt is
heard, release all the buttons, and four
options can be made.
a. Press the <1> button to decrease
the RF channel of operation.
b. Press the <2> button to increase
the RF channel of operation.
c. Press the <Talk> button to
perform a ClearScan™ and select
the clearest RF channel that for
the current environment.
d. Press <1> + <2> simultaneously
to make the selection and exit the
RF selection mode.
5. Once the master beltpack is configured
and running, the other TR-240 beltpacks
should be booted in “wireless” (normal)
mode.
NOTE: Once an RF channel has been selected,
the unit will continue to boot and operate on that
channel until the user sets it to a different
channel.
2 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
2.1 Talk Button
Pressing the <Talk> 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 blink when
the microphone path is disabled.
There are two different modes that dictate how
the <Talk> button behaves when pressed: Push-
to-Latch and Momentary. The talk mode can be
toggled by pressing the <1> + <2> + <Talk>
buttons simultaneously for approx. 3 seconds
followed by a corresponding voice prompt.

2.1.1 Push-to-Latch (default)
Tap the <Talk> button for less than ½ second
and the microphone path will latch and remain
enabled. Tap the <Talk> button again to turn
off the latch and disable the microphone path.
Press and hold the <Talk> button for longer
than ½ second and the microphone path will
continue to be enabled while the <Talk> button
is pressed. The microphone path will be
disabled when the <Talk> button is released.
2.1.2 Momentary
The microphone path will not latch when the
<Talk> button is tapped. The microphone path
will only be activated when the <Talk> button is
pressed.
2.2 Channel Select Button
Pressing the <1> button will activate the audio
from Intercom Channel 1 in the local headset.
Pressing the <2> button will activate the audio
from Intercom Channel 2 in the local headset.
Pressing the <1> + <2> buttons simultaneously
will activate both Intercom Channel 1 and
Channel 2 in the local headset.
The LEDs above each intercom channel button
will be illuminated when active. If the
microphone path is disabled from the talk
button, then the active intercom channel LEDs
will blink.
2.3 Local Headset Volume
The local headset volume can be controlled
from the front panel by turning the <Volume>
knob clockwise and counterclockwise to
increase and decrease the volume, respectively.
2.4 Microphone and Sidetone Levels
After a TR-240 has booted completely, the
microphone gain and sidetone level can be
adjusted. The defaults are:
Mic Gain = 4
Sidetone = 4
2.4.1 Microphone Gain Adjustment
Press the <1> + <Talk> buttons simultaneously
for approximately 3 seconds until a voice
prompt indicates that microphone adjust mode
has been entered. Continue holding the <Talk>
button down and use the <1> button to decrease
the level or the <2> button to increase the level.
As adjusting, voice prompts will indicate the
current level setting. When the desired level is
indicated by the voice prompt, quickly release
all the buttons for one second and that level will
be set.
2.4.2 Sidetone Level Adjustment
Press the <2> + <Talk> buttons simultaneously
for approximately 3 seconds until a voice
prompt indicates that sidetone adjust mode has
been entered. Continue holding the <Talk>
button down and use the <1> button to decrease
the level or the <2> button to increase the level.
As adjusting, voice prompts will indicate the
current level setting. When the desired level is
indicated by the voice prompt, quickly release
all the buttons for one second and that level will
be set.
