AMPLIFIED BLUETOOTH NECKLOOP
USER GUIDE
Moving Beyond the Sound Barrier

Thank you for purchasing the ClearSounds Quattro 4.0 Amplified Bluetooth
Communication System. You are either really smart for purchasing the Quattro 4.0 or
someone really likes you and bought this for you. Or maybe you are both smart AND lucky
to have someone who gave you the Quattro 4.0. Either way, nicely done.
The Quattro 4.0 is an innovative Bluetooth Communication System. Bluetooth is a
technology that uses radio transmissions to exchange data between devices over short
distances. It offers an array of features that will connect you to your mobile phone so you
can actually hear the conversations clearly, connect you to your music & TV; bringing
the joy of entertainment back. It will allow you stress-free meetings & one-on-one
conversations by bringing sound directly to your ears, significantly reducing
background noise.
With all this awesomeness comes some new technology that may require a learning
curve. Have no fear; our remarkably patient & passionate team of Customer Solutions
Consultants are here to help. In addition, we have created a pictorial Quick Start Guide
to get you up & running quickly. And that’s not all! We have developed a series of
instructional videos for those of you who really don’t like manuals.
Welcome

The following precautions are the kind of boring but important information you
should read to ensure maximum performance and safety when using the Quattro
4.0. Although it may seem fairly obvious that standing outside in a lightning storm
wearing an electronic device is not wise, we do have to officially advise you that it’s
not a good idea to do that-- along with these other nuggets of wisdom.

Before using your Quattro 4.0 for the first time, there are four key steps you
need to take to get started.
1. Engage the Battery on both the Quattro 4.0 unit and the QT4 Mic.
2. Charge the Quattro 4.0 and the QT4 Mic.
3. Pair the Quattro 4.0 with your Bluetooth devices.
4. Connect the Quattro 4.0 to your devices paired.
(max. 2 at a time).
In the following pages, we will walk you through each step in this order. At the
back of the manual, you will find a glossary of key terms we use.
It would be a good idea to get familiar with these terms as it will make setting
up and using your Quattro 4.0 much easier. Plus, throwing out some of these
words will make you sound really smart at your next party.
Getting Started
14
Engage the Battery +/-
On the back of both the Quattro 4.0 unit and the QT4 Mic,
there is a small switch labeled +/- . Using a paperclip or pen tip,
move the switch to the + position. This is the only time you
will ever need to touch this switch.
In order to preserve the integrity of the battery while the Quattro 4.0 travels from
the production line to our warehouses and the warehouse of retailers across the
country, we protect it by keeping the battery disengaged.
Similar to the battery pull tab you might see on a new toy or hearing aid
batteries in their packaging, once you remove the tab, the battery becomes
engaged. You will only need to do this once; this is NOT an on/off switch.
Getting Started

Charging will display on the screen and the indicator
light will be red on the QT4 Mic.
The Quattro 4.0 is fully charged when the indicator light
turns blue and 100% Charged displays on the
screen. The battery icon will show full.
Charge your Quattro 4.0 every night for
maximum performance.
To protect your Quattro 4.0 from power
surges while charging, plug into a surge
protector.
Pairing & Connecting
About Pairing: Now that you have the Quattro 4.0 fully charged, it’s time to pair
it to your Bluetooth devices. The first time you use a Bluetooth device with the
Quattro 4.0, you must pair the device with the Quattro 4.0. Pairing is the process
of creating a constant link between the Quattro 4.0 and the Bluetooth device.
Think of it like square dancing in junior high school gym class; The teacher first
“pairs” you with a dance partner, you’re not dancing yet; you’re just standing
there “paired” together.
Charge the Battery
1. Connect the small
USB connector end of
the charging cable to
the Quattro 4.0. Connect
the large USB connector
end to the AC adapter.**
2. Connect the QT4 Mic to
the mic clip. Connect the
small USB connector end
of the charging cable to
the mic clip.***
3. Plug the AC adapter
into a wall outlet or
surge protector.
** You can also charge the Quattro 4.0 by plugging the large USB connector end into the USB port on
your desktop or laptop computer. Make sure the computer is plugged into a power source.
*** If you would like to charge your QT4 Mic and Quattro 4.0 at the same time, connect the QT4 Mic to the
back of the Quattro 4.0 by lining up the pegs and dimples.

2. Follow steps 2 - 4 above. If the device is a 2nd mobile phone with a display,
Quattro 4.0 will appear on the list of connected devices.
The QT4 Mic is already paired to the Quattro 4.0 main unit. No need to go
through the process of pairing these two. We figured this is one less thing
you have to do. However, when you power on the QT4 Mic, if it does not
show on the Quattro 4.0 screen, refer to page 33 to re-pair the mic to the
main unit.
Quattro 4.0 OFF until the new Bluetooth device is in
pairing mode.
About Connecting: Once a device has been paired with the Quattro 4.0 it will
automatically connect moving forward so that you can listen to the device through your
Quattro 4.0. Once connected, the Quattro 4.0 lists the connected device on its
screen. The Quattro 4.0 will automatically connect when:
• The Quattro 4.0 and the device are within 33 feet of each other (in range).
• The Quattro 4.0 and the device are both turned on.
• Bluetooth has been enabled on the device.
Pair & connect the Quattro 4.0 with a Bluetooth-enabled device for
the first time:

1. The Quattro 4.0 must be powered off. We have not provided instructions on
turning it on yet, so unless you’ve gotten ambitious and figured out how to
turn it on, it should still be off.
2. Put your Bluetooth device in pairing mode. Consult the User Guide for
your Bluetooth device for detailed instructions on how to put that device
in pairing mode.
3. On the Quattro 4.0, press and hold the MFB (multi-function button.)
You will see Power On, keep holding MFB until Pairing appears
on the screen.
Getting Started

To break the Bluetooth connection (aka Disconnect):
1. Turn the Bluetooth device off. This breaks the connection; however, when
you turn it back on and the device is still within the 33-foot range, the
Quattro 4.0 will find it & connect.
2. Turn off Bluetooth in the settings of the Bluetooth device. (Follow the
instructions in the Bluetooth device User Guide, if necessary). This allows
you to break the connection while leaving your device on. When you are
ready to re-connect, on the device, turn Bluetooth back on. Once Bluetooth
is turned on, the Quattro 4.0 will automatically find & connect when it
comes within 33 feet of the device.
NOTE: If the Quattro 4.0 is moved outside the Bluetooth connection range (which
is approx. 33 feet), you will hear “out of range” announced. The screen will
revert back to its standby interface. If two devices have been connected
and one of them falls out of range, the screen will refresh and only display
the remaining connected device’s name. If you are on a phone call and
your second device falls out of range, you WILL NOT hear “out of range”
announced until after you have ended the call.
Breaking the Bluetooth Connection
(aka Disconnecting)
You can keep a device paired to the Quattro 4.0, and break the Bluetooth connection
between the Quattro 4.0 and the Bluetooth device.
You would break the connection for the following reasons:
• Since only two devices can be connected to the Quattro 4.0 at once, there
may be a circumstance where you want to keep a device on but want to
“break” its connection to the Quattro 4.0 to make room to connect the
Quattro 4.0 to a different device.
• You are connected to a device you did not want to be connected to.
• You are no longer using the device you are connected to and want to
disconnect until you need it again.

Using the QT4 Bluetooth Mic
So you think using the Quattro 4.0 with your Bluetooth phone
is awesome? Wait ‘til you use the Quattro 4.0 as a personal
listening system! This is the coolest feature ever!
The QT4 Mic has been paired to the Quattro 4.0 unit already out
of the box so there is no need to go through the pairing process.
However, the QT4 Mic is not yet connected to the Quattro 4.0
unit. When you are ready to use the QT4 Mic, you simply need
to “activate” the mic and place it wherever you want (within
33 feet of the Quattro 4.0) to hear it through your t-coil or
SmartSound Earbuds. This brings sound directly to your
ears, reducing background noise and making it easy to hear,
comprehend and listen. The QT4 Mic should not be used while
attached magnetically to the Quattro 4.0 unit. Instead, place
your QT4 Mic as close to the desired sound source as possible.
Be sure to use your QT4 Mic clip for optimal performance. This
is the perfect solution for meetings or classrooms, and noisy
environments like restaurants, etc.

Adjusting your QT4 Mic Sensitivity
Your QT4 Mic is equipped with 4 levels of sensitivity. In a very noisy environment you
can adjust the mic to its highest level and place the mic as close to the sound source as
possible. In a low noise environment you can adjust the sensitivity to a higher level. You
can scroll through the levels until you find one that feels comfortable to you.
