TuneAmp FOCUS SET-UP (continued)General Description
NOTE: Both models are the same in appearance. To
determine which model you have, look at the inside of
the battery door. If you see a blue dot, you have the Basic
model. If there’s an empty space, you have the Focus model.
4General Description General Description 5
Tweak comes in two models:
Tweak Basic and Tweak Focus.
Tweak Basic has a single microphone that picks
up sounds from all directions. It is ideal for quiet
listening environments.
Tweak Focus has two microphones, offering
true directionality for those times that you want
to suppress background noise. The Focus model
is ideal if your lifestyle includes a variety of
environments, both quiet and noisy. Just as its name
implies, the Focus model allows you to focus on
sounds coming from a particular direction.
Tweak comes standard with two common size thin tubes (left and right)
fitted with sleeve tips that will fit most users. A vented dome is also
included, in case you decide you want more bass sounds. (SEE PAGE 8.)
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.
The patented rocker switch is used during initial set up to lock in your
desired amplification setting. Once your amplification selection is made,
the rocker switch also serves as a digital volume control. (SEE PAGE 13.)
On the Focus model, the rocker switch is also used to toggle between
programs for quiet or noisy environments. (SEE PAGE 15.)

6Components Battery Information 7
Tweak uses a commonly available 312 zinc air
battery. With normal full-time use, the battery will
last approximately seven days.
When the battery is depleted, remove and
replace it immediately. Replacements may be
purchased through your retailer. When not in use,
be sure to turn your Tweak off by opening the
battery door part way. (FIGURE 3, PG. 9)
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.

your Tweak is ready for operation.
Place the Tweak over your ear. Grab the loose end of the tubing
and gently insert the tip into the ear canal. Position the retaining lock in
the bowl of the ear. (FIGURE 6)
When properly inserted, the tubing will lay close to the head around the
front of the ear and into the canal. You can check this by moving your
finger down the tubing, into the ear.
Using a mirror at first may be helpful
to properly position Tweak.
If the tip doesn’t stay in your ear,
you may need a different length thin
tube. Additional sizes are available
at TweakHearing.com or by calling

CLEANING LINE
FIGURE 9
FIGURE 10
18 Care Care 19
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.
(FIGURE 10)
(Insert the 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. 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.
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 from your retailer
(or 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. (FIGURE 9)

Care (continued)
20 Care Do’s and Don’ts 21
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 Tweak amplifiers for an extended amount of
time, follow the steps below:
Remove the batteries. Clean your Tweak according to instructions in this
manual. A full cycle in a Dry & Store
®
appliance 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 Dry & Store
®
appliance
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.
(Dry & Store
®
is recommended for storage whenever Tweak is
not being worn.)

Troubleshooting Tips

Troubleshooting Tips (continued)
24 Troubleshooting Tips Troubleshooting Tips 25
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.
Your Tweak may need to be reset. See page 26
for instructions. Once reset, repeat steps on page
12 (Basic model) or page 14 (Focus model) and
choose a lower Amplification Setting. (Example: If
you’re currently on Amplification Setting 3, consider
Amplification Setting 2.)
If the above fails to reduce feedback, contact your
place of purchase.
Sound is Distorted,
Unclear, Intermittent
or has Static Noise
Replace the battery.
Make sure the tube and tip are not clogged.
(Refer to page 19.)
Make sure the amplifier is clean and dry. We
recommend nightly use of a Dry & Store appliance 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 need to be reset. See page 26
for instructions. Once reset, repeat steps on page
12 (Basic model) or page 14 (Focus model) and
choose a lower Amplification Setting. (Example: If
you’re currently on Amplification Setting 3, consider
Amplification Setting 2.)
Your Tweak may have a poor battery contact or
may not be set up properly. Contact your place of
purchase.
