Editing Transmitter Parameters:
The easiest and most intuitive way to set the parameters of ClearOne transmitters and receivers is with ClearOne
DIALOG 20 Software. Download the software from www.ClearOne.com. Load the Software onto a computer
running Windows 7 or above (32 or 64-bit). Connect to the receiver via the USB connection located on the back
panel. There is a micro-USB to USB cable provided with the receiver. Use this cable to power the receiver and to
connect it with a computer to configure the system.
Open The Channel Edit Window:
1. Open ClearOne Remote and select ONLINE.
2. The [Click to Edit] function opens the edit window of the channel you wish to edit.
3. Select the functions you want to edit and enter the parameter (The various functions are described below).
Click [OK] to save the changes and close the Channel Edit window.
4. You will notice that the [Needs to Sync] alert is lit. This indicates that one or more parameters are in queue
in the receiver ready to be downloaded and implemented with the next transmitter Sync of the channel.
Refer to the Software User Manual for detailed instructions on how to use the software and all of it’s features.
ClearOne DIALOG 20 Software provides the following functions:
• File: The file menu allows the current receiver settings to be saved to a file on your computer or for a
previously saved file on your computer to be recalled to the receiver.

name.
• RF Scan - RF Plot: Shows the RF strength of each antenna in a ClearOne system and shows if there is
outside interference.
• GPIO: Allows muting of output or input.
• Alert: Gives the user the ability to set alert conditions, such as, low battery, battery runtime hours, low RF
signal, and Transmitter turned off.
• Help: The “About” tab contains the system information.
Select new parameter values,
click “Apply and Close”.

Modifications (FCC 15.21)
Warning:
Changes or modifications to this equipment not expressly approved by ClearOne may void the user’s authority to operate
this equipment according to your local radio regulatory authorities.
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two con-
ditions: (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.
Applies to Beltpack (910-6004-00X):
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
isotopically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
This radio transmitter (910-6004-00X) has been approved by Industry Canada to operate with the antenna types listed
below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna
types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for
use with this device.
Monopole antenna, 0dbi gain, 50 ohm impedance.
Le présent émetteur radio (910-6004-00X) a été approuvé par Industrie Canada pour fonctionner avec les types d’antenne
énumérés ci-dessous et ayant un gain admissible maximal et l’impédance requise pour chaque type d’antenne. Les types
d’antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour
l’exploitation de l’émetteur.
France:
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 com-
promettre le fonctionnement.
Clearone Wireless Receivers, Transmitters, and, Antennas are intended for indoor use only.

Electronic Code of Federal Regulations
Title 47: Telecommunication
PART 15—RADIO FREQUENCY DEVICES
Subpart B—Unintentional Radiators
§15.105 Information to the user.
(a) For a Class A digital device or peripheral, the instructions furnished the user shall include the following or similar state-
ment, placed in a prominent location in the text of the manual:
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
(b) For a Class B digital device or peripheral, the instructions furnished the user shall include the following or similar state-
ment, placed in a prominent location in the text of the manual:
Note: 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 ac-
cordance 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 cor-
rect 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.
(c) The provisions of paragraphs (a) and (b) of this section do not apply to digital devices exempted from the technical
standards under the provisions of §15.103.
(d) For systems incorporating several digital devices, the statement shown in paragraph (a) or (b) of this section needs to
be contained only in the instruction manual for the main control unit.
(e) In cases where the manual is provided only in a form other than paper, such as on a computer disk or over the Inter-
net, the information required by this section may be included in the manual in that alternative form, provided the user can
reasonably be expected to have the capability to access information in that form.
