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 40-50 hours in the TX900BP
transmitter and approximately 50-60 hours in the RX900BP receiver. If the sound becomes
distorted or weak, it is time to replace the batteries.
RECHARGEABLE BATTERIES
The TX900BP transmitter and RX900BP receiver can use 1.25V AA NiMH rechargeable
batteries (ARG-BCRAA). After charging for 5-6 hours, these NiMH batteries are designed to
operate a TX900BP transmitter for approximately 40-50 hours and a RX900BP receiver for
50-60 hours.
IMPORTANT RECHARGEABLE BATTERY INFORMATION
Batteries MUST BE CHARGED for a complete cycle before the firstuse.
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 or product.
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 toxic chemicals.

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 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 900Mhz 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: ARG-TX900 Transmitter
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. Do not bunch up the cord, wrap it tightly around your body or wrap it around the transmitter.
Use only Talk & Listen® approved microphones; substitutions can greatly affect the overall
performance therefore causing poor audio quality.
4. Turn the power switch on top of the Transmitter to “ON”. The LCD backlight will turn on and remain
on until the power is turned off. The LED will turn orange indicating the power is on; red flashing
indicates the battery is charging and solid red indicates the batteries are fullycharged.
5. Confirm that the channel number on the transmitter matches the number on the receiver(s). To adjust
the channel number, open the battery compartment door and locate the “LOCK” button; press and
hold it for three seconds to unlock the transmitter. The “LOCK” icon on the LCD display will disappear
once the unit is unlocked. Use the “-“button on the front panel to scroll through the channels and
choose the appropriate channel. When completed, press and hold the “LOCK” button for three
seconds to relock the transmitter, the “LOCK” icon will reappear on the display. Close the battery
compartment door. The channel numbers range from 1-12 and are located on the left side of the LCD

the low pass filter setting. When completed, press and hold the “LOCK” button for three seconds to
relock the transmitter, the “LOCK” icon will reappear on the display, close the battery compartment
door. The low pass filter settings range from 1-8; increasing the filter setting decreases unwanted
high frequencies while maintaining an acceptable audio range. The display number will go blank after
you scroll past “8” which indicates the low pass filter is turned completely off. The number located on
the right side of the LCD display is the low pass filter setting. The factory setting is “2”.
8. RF Level Adjustment: To adjust, make sure the transmitter is turned 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. To adjust this setting use the “+” and “-“ buttons to cycle through the settings.
There are 4 individual RF level settings. The signal meter icon on the LCD display is used to indicate
the current programmed RF level. Settings are +3dBm (1 signal bar); +6dBm (2 signal bars); +9dBm
(3 signal bars); and +13dBm (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. The factory setting is 4 signal bars; the highest setting.
9. When finished using Transmitter, make sure to power off.

FCC Compliance
The ARG-TX900BP 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 TX900BP transmitter and the earphone/headphone is plugged in
the RX900BP 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.
