FAQ’s
Q: Why doesn’t the dongle work when plugged into my mixer?
A: Plugging the dongle when the Phantom Power “ON” may trigger a protection circuit,
remove the dongle from the mixer, turn “OFF” the Phantom Power, wait for 60 seconds
and try again.
Q: Why is the audio output level so low?
A: Raise the volume on your source device (phone, tablet, etc.…).
Q: Why does the dongle have a red LED blinking and I cannot connect to the dongle
though I waited for more than 30 Sec?
A: Continuous red blinking LED is mostly caused by losing connection to the source, for
example if the operator left the room with the phone or tablet and the connection was
compromised, connection can be restored by resetting the 318BT using the Reset button.
Q: Why doesn’t the dongle work on Phantom Power while working well on USB power?
A: The Phantom Power on your mixer has to be greater than 46.5V.
Q: I cannot get a good range! The audio starts breaking with less than 100’ distance!
Why?
A: The human body blocks the high frequency Bluetooth®signal, if you are using a
Smartphone, it is not recommended to put it in your pocket while streaming, also Line-Of-
Sight operation will enhance the range.
Q: Can I connect the Dongle to a Bluetooth®speaker or headphone?
A: No, the unit only acts as “Slave” and can only be connected to a “Master” device
(Phone, tablet, PC...etc.).

FCC Part 15 Class B digital device (commercial/residential use)
FCC Compliance
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna; Increase the separation between the equipment and receiver;
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected; Consult
the dealer or an experienced radio/TV technician for help.
To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance
of 20 cm or more should be maintained between the antenna of this device and persons during operation. To
ensure compliance, operation at closer than this distance is not recommended. The antenna used for this
transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

Industry Canada Radio Standards Specification (RSS) RSS-210
RSSGen and ICES-003
Canada - IC
This device complies with Industry Canada license exempt RSS standard(s). Operation is subject to the following
two conditions: (1) this device may not cause interference, and (2) this device must accept any interference,
including interference that may cause undesired operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de
licence. L'exploitation est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire de
brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage
est susceptible d'en compromettre le fonctionnement.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and
maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference
to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une
antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but
de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type
d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité
nécessaire à l'établissement d'une communication satisfaisante
