BATTERY SAFETY AND INSTRUCTIONS
RECYCLING INSTRUCTIONS
Please help ARG protect our environment by taking time to properly dispose of your used
batteries. Do NOT throw into household trash: Please recycle by taking them to a local
recycling collection center.
NON-RECHARGEABLE BATTERIES
In normal use, two AA 1.5V alkaline batteries will last about 30-40 hours in the ARG-
TX72BP. If the sound becomes distorted or weak, it is time to replace the batteries.
RECHARGEABLE BATTERIES
The TX72BP transmitter can use 1.25V AA NiMH rechargeable batteries. After charging for
5-6 hours, these NiMH batteries are designed to operate a TX72BP transmitter for
approximately 30-40 hours.
IMPORTANT RECHARGEABLE BATTERY INFORMATION
Batteries MUST BE CHARGED for a complete cycle before the first use.
Rechargeable batteries will normally need to be replaced after 1-2 years ofuse.
Do not leave batteries installed for long periods of inactivity as they may leak. (Battery
leakage is not covered by warranty)
CAUTION!
Do not attempt to recharge disposable batteries, which may explode, release
dangerous chemicals, cause burns or other serious harm to the user orproduct.
Avoid shorting the batteries by placing plus and minus battery terminals together with
metal objects. Battery damage and burns can result!
Do not dispose of batteries in fire.
Do not open batteries as they contain toxicchemicals.

SYSTEM OVERVIEW
The Talk & Listen® System is a portable, high-performance communication system designed to
be used for many types of communication applications. It is composed of five principal
components: transmitter, microphone, receiver, listening equipment (headphone, earphone, ear
bud, etc.) and batteries.
The TX72BP Transmitter broadcasts a high-quality one-way audio signal to an unlimited
number of receivers providing crystal clear FM quality audio to each listener. Much like a
miniature radio station, the speaker uses a transmitter to broadcast a radio signal while the
listeners use a receiver to hear the signal. The transmission range of this system is 100m LOS
(Line of Site).
ARG’s updated 72MHz Talk & Listen® System showcases many new features including
adjustable RF levels; user-friendly scroll-and-click commands; mono and stereo input; and
durable, attractive housing.
HINTS to Using the TALK & LISTEN® Wireless System
Maximum operating distance between the transmitter and receiver is 100m (LOS). The
operating range will vary in different environments. In some locations, the signal may
momentarily disappear. This is called a drop-out signal and is due to reflection and cancellation
of the radio signal. Moving a few feet in any direction should restore thesignal.
Getting transmitters too close to one another may cause signal interference, even when they
are set to a different channel. Maintain at least three feet of separation between transmitters to
avoid signal interference.
Receivers are not subject to interference when in close proximity to one another therefore
listeners may sit close together whether on the same or different channels. If a receiver gets too
close to a transmitter, interference may occur. Maintain three feet of separation between a
transmitter and receiver to avoid interference.

OPERATING INSTRUCTIONS
1. Before installing batteries, determine if they are carbon zinc, heavy duty, alkaline or rechargeable. Open the
battery compartment door and locate the “ALK/NiMH” switch. If using carbon zinc, heavy duty or alkaline
batteries slide the switch to the “ALK” position; if using NiMH rechargeable batteries slide the switch to the
“NiMH” position.
2. Install (2) AA style batteries by pressing them into place, observing the proper battery polarity. Incorrect insertion
may cause both mechanical and electrical damage not covered by the limited lifetime warranty. Units will not
work if the batteries are incorrectlyinstalled.
3. Plug the microphone into the 3.5mm audio input jack located on the left side of the transmitter housing. The
microphone cable is the transmitter antenna. Do not bunch up the cord, wrap it tightly around your body or wrap
it around the transmitter. For maximum range, the cord should hang loosely from the microphone to the
transmitter. Use only Talk & Listen approved microphones, substitutions can greatly affect the overall
performance therefore causing poor audio quality or reduced transmission range between the transmitter and
receiver(s).
4. Turn the power switch on top of the transmitter to “ON”. The LCD backlight will appear and stay on until it detects
10 seconds of inactivity, it will then automatically shut off to save battery power. The LCD backlight will
automatically turn back on once any of the control buttons are pressed.
5. Channel setting (1–17): Confirm the channel number on the transmitter matches the number on the receiver (s).
To adjust the channel number, turn the transmitter OFF; open the battery door, press and hold the “Lock” and
“Set” buttons simultaneously while turning the transmitter power ON, the green backlight on the LCD display will
illuminate showing the current channel number programmed; press the “-” or “+” buttons to scroll through and
select one of the 17 available channels. When finished, close the battery door and turn the transmitter off. The
transmitter is now programmed to your desiredchannel.
6. Audio Mute: To temporarily silence during use, press and hold the “-” button until the “Gain Indicator” (number
on the right of the screen under the LCD display) starts to flash, this indicates the audio has been muted.
Repeat the process to restore the audio signal. The “Gain Indicator” icon will stop flashing.
7. Gain Setting: When using the line input for auxiliary equipment (such as CD player or iPOD™), turn the “Gain
Control” to “1”; higher levels will distort audio. To adjust the gain setting, turn the transmitter ON; open the battery
door, press and hold the “Lock” button till the Lock icon disappears from the LCD display; press the “Set” button
to scroll through and select 1 for microphone or 2 for line levelaudio.
8. RF Level Adjustment: turn the transmitter off; open the battery door, press and hold the “Set” button and
simultaneously turn the transmitter ON to enter into the RF Level Programming mode. There are 5 individual RF
level settings. The signal meter icon on the LCD display is used to indicate the current programmed RF level.
Settings are -1dBm (no signal bar-lowest setting); +3dBm (1 signal bar); +7dBm (2 signal bars); +11dBm (3
signal bars); and +15dBm (4 signal bars-the highest RF Level Setting). Press the “SET” button to scroll through
and select the RF level setting. When finished, close the battery door and turn the transmitter OFF to exit
programming mode.
9. When finished using Transmitter, make sure to poweroff.

ARG-TX72 Transmitter FCC Compliance
The ARG-TX72BP is authorized by rule under the Low Power Radio Service (47 C.F.R. part 95) and must not
cause harmful interference to TV reception or United States Navy SPASUR installations. You do not need an
FCC license to operate this transmitter. This transmitter may only be used to provide: auditory assistance to
persons with disabilities, persons who require language translation, or persons in educational settings;
healthcare services to the ill; law enforcement tracking services under agreement with a law enforcement
agency; or automated maritime telecommunications systems (AMTS) network control communications. Two-way
voice communications and all other types of uses not mentioned above are expresslyprohibited.
Operation is subject to the following two conditions:
1) this device may not cause interference
2) this device must accept any interference, including interference that may cause undesired operation of
the device
TROUBLESHOOTING
1. Read through the manual and user guide carefully to verify proper setup and installation of the transmitter
and receiver(s).
2. Make sure the batteries are fresh or completely charged and that the “plus” and “minus” terminals are
correctly placed.
3. If the rechargeable batteries will only work for a short period of time (less than 1 hour) even after they have
been fully charged; they must be regenerated. Turn the transmitter(s) on until the batteries are completely
dead, and then fully charge again. This should restore normal battery life. Rechargeable batteries will
gradually lose their capacity over time and should be replaced every 1 to 2years.
4. Make sure the microphone is plugged into the TX72BP transmitter and the earphone/headphone is plugged
in the RX72BP receiver.
5. Move the transmitter and receiver closer together as you may be out of range. When using the system
indoors, it is normal for the signal to momentarily disappear in certain locations. This is called a “drop-out”.
Moving a few feet in any direction may restore thesignal.
6. When using two or more transmitters simultaneously do not use adjacent channels if possible, for example:
if you have a 3-channel system and you want to use two transmitters simultaneously, set TRANSMITTER
ONE to channel 1 and TRANSMITTER TWO to channel 3; leaving channel 2 as an unused channel. This
creates more spacing between the channels and reduces the likelihood ofinterference.
7. If you are still hearing interference, turn the transmitter off and listen to a receiver. If you hear the
interference with the transmitter off, you need to change to a clearchannel.
8. If you are still experiencing difficulties, call ARG888-468-4552.
