Tweak Focus+T has three listening modes: omni-
directional (for quiet environments), directional
General Description
(for noisy environments), and
telecoil for use with telephone
and loop systems. The noise
mode suppresses background
noise, allowing you to focus on
sounds coming from a particular
direction.
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.
Each time it‘s powered on, Tweak will start in omni-directional
(Quiet) mode at mid-volume.

Battery Information
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

20 Caring for Your Tweak 21
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.
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.
(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 cleaning.
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.
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

DO
DON’T
22 Caring for Your Tweak 23
* Drying appliances by Dry & Store include the DryMax,® Global II,
Zephyr, DryDome,® or DryCaddy.®
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 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 drying
appliance 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.

24 Troubleshooting Tips 25
No Sound or Not
Loud Enough
Ensure that the battery door is closed.
Replace the battery.
Make sure the tip/dome is not clogged.
(Refer to page 20 for cleaning instructions.)
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 9mm dome tip and attach
one of the larger dome tips. Try a vented
dome first, and if still not enough sound, try
a closed dome. Be sure to secure the tip/
dome. See page 12. If feedback continues,
consider changing to an earhook with a
dome.
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 27 for instructions
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/dome 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 4
consider using the larger (12mm) vented
dome instead of the 9mm dome. If feedback
continues, consider using one of the closed
domes or change to an earhook with a
dome.
Your Tweak may need to be reset. See
page 27 for instructions. (For example: If
you’re currently on Amplification Setting 4,
consider Amplification Setting 3.)
If the above fails to reduce feedback, call
Tweak Support at 1-888-815-3240.
Troubleshooting Tips

26 Troubleshooting Tips How to Reset 27
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 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
or may not be set up properly. Call Tweak
Support at 1-888-815-3240.
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 vented dome
tip and attach one of the closed 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 17.
