6 General Description
Tweak comes in two models: Tweak Focus and Tweak
Focus+T.
General Description
Tweak Focus has two listening
modes: omni-directional (for quiet
environments) and directional (for
noisy environments). The noise
mode suppresses background
noise, allowing you to focus on
sounds coming from a particular
direction.
Tweak Focus+T has everything the
Focus model has, plus a telecoil
for use with telephone or loop
systems. It has three modes: omni-
directional, directional, and telecoil.
The rocker switch is used during
initial set up to try out and then lock
in your desired amplification setting
that becomes your amplification
‘profile’, and it stays with you as
you switch between Quiet, Noise
and Telecoil modes. You can still
fine tune it using the rocker switch
volume control.
The program button is used to
switch between listening modes for
Quiet, Noise, and Telecoil.
During set-up you’ll learn how to position the Tweak
on your ear and how to pick your favorite amplification
setting. Your Tweak package includes:
2 Small Tubes (Right and Left) with Sleeve Tips
pre-installed
1 Large Vented Dome Tip
1 Large Closed Dome Tip
The thin tube delivers amplified sound from Tweak into your ear. It
is important for the sound tube and tip to fit properly in your ear.
If you need a different size tip or tube, call 1-888-815-3240 or visit
TweakHearing.com to purchase the appropriate size.

Battery Information 9
8 Components
Components Battery Information
Included COMPONENTS
Tweak uses a commonly available 312 zinc air battery. With
normal full-time use, the battery will last approximately
five to seven days.
When the battery is depleted, remove and replace it
immediately. When not in use, be sure to turn off your
Tweak by opening the battery door part way.
Low Battery Warning
For your convenience, Tweak warns you when the battery
is almost depleted. You will hear three sets of double
beeps every 10 minutes, which indicates it’s time to
change the battery. Once the voltage drops below 0.95V,
Tweak emits six sets of double beeps, then shuts down.
IMPORTANT —
Always discard used batteries.
Small batteries can be harmful if
swallowed. Keep batteries out of
reach of pets and small children.
In case of ingestion, seek medical
attention immediately and
call (collect, if necessary) the
National Battery Ingestion
Hotline at 202-625-3333. For

18 Caring for Your Tweak
Caring for Your Tweak
The following instructions will assist in extending the life
of your Tweak amplifier.
Cleaning the Exterior
You should inspect and clean your Tweak 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.
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. 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 Tweak’s
electronics.
Cleaning the Tip and Tube
Remove the tube from the case
by twisting the tube connector at
least 45° then pulling it off.
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.
(Insert the cleaning line at the
connector end where the tube
attaches to the amplifier case
and push out through the tip.)
IMPORTANT:
Do not use cleaning line while tube is attached to device.
Tube must be detached from the instrument before cleaning.
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.

Caring for Your Tweak continued
* Drying appliances by Dry & Store include the Global II, Zephyr,
DryDome,® or DryCaddy.®
Extended Storage
If it is necessary to store your Tweak amplifiers for an
extended amount of time, follow these steps:
Remove the batteries. Clean your Tweak according
to instructions in this manual. A full cycle in a drying
appliance* by Dry & Store® is recommended prior to
extended storage. Place Tweak in an airtight container
with a desiccant such as a Dry-Brik® or DryCaddy® disc.
Then store in a cool, dry place.
Do Place your Tweak amplifiers in a dryer by
Dry & Store every night to remove moisture and
prevent corrosion.
Do Always carry spare batteries.
Do Safely store Tweak 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 Tweak is not being worn.)
Don’t Leave Tweak 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 Tweak when using a hair dryer or when at
the beauty salon, spa or barber.
Don’t Apply hair spray when wearing your Tweak. It
can damage the microphone or other components.
Don’t Wear Tweak while taking a bath, shower, spa
treatment or while swimming.
Don’t Store Tweak in the bathroom during a shower or
near a steam room, as moisture created by the steam
may cause damage.

22 Troubleshooting Tips
Troubleshooting Tips
Whistling
(“Feedback”)
Your Tweak 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 is positioned
properly in the ear canal.
Try adjusting the volume. Tap the lower
portion of the rocker switch to decrease
volume.
If already using amplification setting 3
consider using one of the domes instead of
the sleeve tip.
Your Tweak may need to be reset. See
page 25 for instructions. (For example: If
you’re currently on Amplification Setting 3,
consider Amplification Setting 2.)
If the above fails to reduce feedback, call
Tweak Support at 1-888-815-3240.
No Sound or Not
Loud Enough
Ensure that the battery door is closed.
Replace the battery.
Make sure the tip 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 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. See page 19.
Excessive ear wax can prevent sound from
entering the ear. Contact your physician.
Changes in your hearing can affect how
you hear with Tweak. Contact a hearing
healthcare professional if you suspect any
change in your hearing condition.
Your Tweak may need to be reset for more
volume. See page 25 for instructions

How to Reset 25
24 Troubleshooting Tips
Troubleshooting Tips continued How to Reset
After wearing Tweak 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.
Tweak may be reset by following these simple steps:
1With a battery inserted, open the battery door.
2Press and hold the rocker switch.
3While still pressing and holding the rocker switch,
close the battery door.
4Wait at least 14 seconds, then release the rocker
switch.
5Open the battery door.
6When you close the battery door again, Tweak is
reset.
You may now proceed to select a new
Amplification Profile. See page 13 for Focus model
or page 15 for Focus+T model.
Sound is
Distorted,
Unclear,
Intermittent or
has Static Noise
Replace the battery.
Make sure the tube and tip are not
clogged. (Refer to page 18-20 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 Tweak may have a poor battery contact
