A breakthrough in personal sound amplification technology
Ear Technology Corporation proudly
offers a breakthrough in personal sound
amplification technology: TweakConnect.
TweakConnect is a personal sound
amplifier that pairs the sophisticated
sound processing and easy
personalization of Tweak hearing products
with the most intuitive app on the market.
Other products force you through a
hearing test, then program the hearing
device with an algorithm that THEY
decide is ‘best’ for you. TweakConnect
gives YOU “The Power of Choice,”
enabling YOU to select the settings that
provide the best result for you. With the
app on your smartphone, you can easily
fine tune and further adjust the settings at
a moment’s notice no matter where you
happen to be. Tweak contains the same
components found in high-end hearing
aids that cost thousands of dollars: digital
signal processing, high-end feedback
cancellers, microphones, speakers,
and bio-compatible plastics. It also
incorporates a digital volume control to
give you even more flexibility in different
environments.

Caring for Your TweakConnect
The following instructions will assist in extending
the life of your TweakConnect amplifier.
Cleaning the Exterior
You should inspect and clean your TweakConnect
every day. To clean, gently wipe the surface with a
soft, dry cloth or a moist non-alcohol disinfecting
wipe. Do not allow water or liquid to enter any
openings.
The most common causes of amplifier problems are
moisture and wax. The daily use of a Dry & Store®
appliance is recommended to reduce moisture
and wax buildup. Dry & Store products may be
purchased at www.dryandstore.com.
Cleaning the Tip and Tube
Remove the tube from the
case by
twisting the tube
connector at least 45° then
pulling it off
. Use the same
method for an earhook.
Wipe the exterior of the tube
and tip. Use the cleaning line
provided to clean the tube and
tip, by pushing the cleaning line
through the tube. A brush is
also included for cleaning debris from the dome tip.
24 Caring for Your TweakConnect
25
(Insert the cleaning line at the connector end where
the tube attaches to the amplifier case and push out
through the tip.)
Re-attach the tube by aligning the tube connector
end with the end of the amplifier case, then
push
the connector straight onto the sound post until
it snaps into place
. There is no need to rotate the
tube when re-attaching.
Do not rinse or submerge these parts in water.
IMPORTANT:
Do not use cleaning line while tube is attached to device.
Tube must be detached from the instrument before cleani ng.
There is a risk of damage if a water
drop becomes trapped in the tube. If
this should occur, it will prevent sound
from coming through the tube and
may be harmful to TweakConnect’s
electronics.
* Drying appliances by Dry & Store include the DryMax®,
DryMax-UV, Global II, Zephyr, DryDome,® or DryCaddy.®
Changing the Tube and Tip
The tube and tip should be changed periodically,
typically 2 or 3 times per year. When the tube or tip
become soft, discolored, kinked, or damaged, obtain
replacements by calling 1-888-815-3240 or visiting
TweakHearing.com
When you change the tip, make sure it is securely
fastened to the sound tube before inserting it in
your ear.
Extended Storage
If it is necessary to store your TweakConnect
amplifiers for an extended amount of time, follow
these steps:
Remove the batteries. Clean your TweakConnect
according to instructions in this manual. A full
cycle in a drying appliance* by Dry & Store® is
recommended prior to extended storage. Place
TweakConnect in an airtight container with a
desiccant such as a Dry-Brik® or DryCaddy® disc.
Then store in a cool, dry place.

Troubleshooting Tips 27
Do Place your TweakConnect amplifiers in a dryer
by Dry & Store every night to remove moisture and
prevent corrosion.
Do Always carry spare batteries.
Do Safely store TweakConnect when not in
use. Keep out of reach of small children and
pets. In particular, dogs may be irritated by the
feedback (“whistling”) sound and attracted by
the owner’s scent. This often results in a chewed
and/or ingested device. (A drying appliance by
Dry & Store is recommended for storage whenever
TweakConnect is not being worn.)
Don’t Leave TweakConnect on the radiator, near a
stove, in a sunny window, in a car or in any other
hot place. Excessive heat or cold can damage the
instrument.
Don’t Wear TweakConnect when using a hair dryer
or when at the beauty salon, spa or barber.
Don’t Apply hair spray when wearing your
TweakConnect. It can damage the microphone or
other components.
Don’t Wear TweakConnect while taking a bath,
shower, spa treatment or while swimming.
Don’t Store TweakConnect in the bathroom during
a shower or near a steam room, as moisture created
by the steam may cause damage.
Troubleshooting Tips
No Sound or Not
Loud Enough
Ensure that the batter y door is closed.
Replace the battery.
Make sure the tip/dome is not clogged.
Make sure the amplifier case and tubing are
clean and dry.
Make sure that the amplifier case is
positioned properly behind the ear, and that
the tip/dome is positioned properly in the
ear canal.
Make sure the volume is turned up, by
tapping the upper portion of the rocker
switch.
Remove the sleeve tip and attach one of the
dome tips. Try the vented dome first, and if
still not enough sound, try the closed dome.
Be sure to secure the tip/dome. See page 12.
Excessive ear wax can prevent sound from
entering the ear. Contact your physician.
Changes in your hearing can affect how you
hear with TweakConnect. Contact a hearing
healthcare professional if you suspect any
change in your hearing condition.
Your TweakConnect may need to be reset
for more volume. See page 33 (“How to Start
Over”) for instructions
28 Troubleshooting Tips

Troubleshooting Tips continued
Whistling
(“Feedback”)
Your TweakConnect has a best-in-class
feedback management system. However,
when your hand is near the device, you
may hear a whistling noise, which is called
“feedback.” This may be caused by amplified
sound bouncing off your hand back into the
instrument. The noise usually quits when
you take your hand away.
If the whistling doesn’t stop once you’ve
moved your hand away, ensure that the
amplifier case is positioned properly behind
the ear, and that the tip/dome is positioned
properly in the ear canal.
Try adjusting the volume. Tap the lower
portion of the rocker switch to decrease
volume.
Consider using one of the domes instead
of the sleeve tip. If feedback continues,
consider using one of the more closed
domes or change to an earhook with a
dome.
Your TweakConnect may need to be reset.
See page 33 (“How to Start Over”) for
instructions.
If the above fails to reduce feedback, call
TweakConnect Support at 1-888-815-3240.
Sound is
Distorted,
Unclear,
Intermittent or
has Static Noise
Replace the battery.
Make sure the tube and tip/dome are not
clogged. (Refer to page 23 for cleaning
instructions.)
Make sure the amplifier is clean and dry.
We recommend nightly use of a drying
appliance by Dry & Store to remove
moisture and prevent corrosion.
If you are near an electromagnetic field
(e.g. near a computer screen or fluorescent
lights), step away to see if the static clears.
Your TweakConnect may have a poor
batter y contact or may not be set up
properly. Call TweakConnect Support at
1-888-815-3240.

How to Start Over 33
How to Start Over
After wearing TweakConnect for a while, you may
decide you want to try a different Amplification
Profile than the one you initially selected. However,
if you simply want more bass sound, remove the
sleeve tip and attach one of the dome tips instead.
This may resolve the issue and resetting is no longer
necessary.
TweakConnect may be reset by selecting the “Start
Over” option on the Main Menu of the app.
