PRIOR TO USE

Congratulations on your purchase of the QUATTRO Amplified
Neckloop from ClearSounds Communications®. Please read
this User Manual carefully in order to get the best use out of
your new accessory. Keep this manual safe for easy reference.

Please visit our website at www.clearsounds.com to register
your product, download additional manuals and review trouble­shooting tips.

Be sure to save your sales receipt as your proof of purchase
should you need warranty service. The serial number for this
product is located on the backside of the unit.

The QUATTRO generates an amplified induction (loop) signal
that is picked up by the telecoil of your hearing aid(s) or
cochlear implant processor(s). This option in the hearing
device is activated by setting the hearing aid(s) or cochlear
processor to the “T” or “MT” position. The QUATTRO has been
developed to facilitate the use of a Bluetooth capable cellular
phone, landline phone, or audio device including stereo audio
devices with a t-coil equipped hearing device for hands-free
wireless operation. The QUATTRO now also accommodates a

3.5mm headset jack for users without t-coils, hearing aids, or
cochlear implants to enjoy the same hands-free functionality
of this stereo device by using a regular 3.5mm headset
or ear buds.

Warranty Service – This product is designed to provide years
of quality service. However, if there is a malfunction and the
troubleshooting recommendations on page 18 do not resolve
the problem, follow the warranty procedure on page 20.

switch your device to “T.”

11 – ENGLISH

█ PAIRING TO A CELL PHONE

Before using your QUATTRO for the first time, you must pair it
with your Bluetooth phone. “Pairing” creates a link between
your Bluetooth equipped cell phone and the QUATTRO, and it
allows your cell phone to remember the QUATTRO’s unique
ID by adding it to a list of paired devices in the phone. The
QUATTRO should be paired once with the phone before use.
Once your QUATTRO and phone are paired, your QUATTRO
automatically connects to your phone if the phone supports
that protocol. Some phones may ask if you want to manually
connect to a Bluetooth device. Check your phone’s manual for
more details on how its Bluetooth functions operate.
Please Note: If the pairing information or log is deleted from
your phone, the QUATTRO unit must be paired again with the
phone prior to use.

To Pair:

1. Place the QUATTRO and phone close to each other (within
3 feet). Make sure that your phone is on.

2. With your QUATTRO off, press and hold the Multi Function
Button for approx. 6 seconds. Make sure that you continue
to hold the Multi Function Button until you see the LED
indicator flash red and blue alternately. The QUATTRO
is now in pairing mode and will stay in pairing mode for
approx. 2 minutes.

3. Enter the Bluetooth menu on your phone and perform a
device search (for the details on device search for your
phone, refer to your owner’s manual). When the scan is
complete, the phone displays the devices discovered.

4. Select Cla7 STEREO BT from the list of devices discovered
and confirm.

5. When prompted by the phone, enter the passkey as
‘0000’. Your phone will confirm that pairing has occurred
and the QUATTRO will confirm it paired successfully with
10 rapid flashes.

FUNCTIONS

12 – ENGLISH

6. The phone information is now stored in the QUATTRO
memory.

7. The QUATTRO LED indicator will flash blue every 3 seconds
when paired and is now in standby mode, ready to make or
receive calls.

If the QUATTRO is not successfully paired within 2 minutes, it
will automatically leave pairing mode. If you still want pairing,
you will need to repeat the steps listed above.

IMPORTANT:

1. After the connection, if you want your cell phone to connect
automatically the next time you power on the QUATTRO,
set the QUATTRO as your authorized device or auto connect
device on your cell phone menu.

2. If you want to connect your QUATTRO to another Bluetooth
enabled device, you will need to disconnect the QUATTRO
with the paired device before establishing a connection
with the intended device.

3. Make sure the QUATTRO and phone you are using are no
more than 33 feet apart so they are within operable range.

4. If the link disconnects, (for example, the device is out of
range) the QUATTRO tries to re-establish the link and will
search for the device for a period of time.

5. The QUATTRO will automatically try to connect to the last
connected phone when powered ON for the first 90 seconds.

Disconnect Options:

1. Power off the QUATTRO

2. Switch off the Bluetooth function on the cell phone

3. Separate the QUATTRO from the cell phone at a distance of
65 feet or more.

█ PAIRING TO ADDITIONAL DEVICES

The QUATTRO now includes the Advanced Audio Distribution
Profile (A2DP) and can also connect to Bluetooth enabled
stereo audio devices for streaming media. Your QUATTRO can

13 – ENGLISH

store pairing information for up to eight (8) different devices
with Bluetooth wireless capability. Devices are stored in a
“Paired Device List” in the memory in a time sequence. When
an attempt to pair more than eight devices is made, the oldest
paired device is removed from the memory list. Any of the
eight paired devices can initiate a connection to the QUATTRO.

The QUATTRO will automatically initiate a connection (once
turned on) with the last device to which it was connected.
If you want to connect the QUATTRO to another device in
the paired device list, you must initiate the connection
from that device. When any of the eight devices initiates a
connection to your QUATTRO, that device then becomes the
“last connected” device.

█ ADJUSTING VOLUME

The receiving volume can be adjusted during a call or when
listening to other audio sources. The volume setting on the
cell phone or other device will add or remove amplification
from the overall system. If amplification is low, check the
volume level on both units. If there is distortion or other
interference, lower the volume on one or both of the units.
Too much amplification can cause distortion.

Adjustment while using the neckloop with t-coils

Use the volume control wheel located on the left side
of the unit (on your right when it is being worn). Slide
the wheel up to increase the volume and slide it down to
decrease the volume.

Adjustment while using a headset

Use the volume control buttons located on the left side
of the unit (on your right when it is being worn), which
is below the volume control wheel used for the neckloop.
Press the + button once to increase the volume and press
the – button once to decrease the volume. To continue
increasing or decreasing volume, pressthe + or – button

14 – ENGLISH

repeatedly, but do not press and hold for longer than 1
second as this will activate the Track Selection function
(see page 18).

█ MAKING AND RECEIVING CALLS
