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 expressly prohibited.
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 2 years.
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 the signal.
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 of interference.
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 clear channel.
8.
If you are still experiencing difficulties, call ARG 888-468-4552.
