Turning ON and OFF
Volume Control
Turn ON/OFF – Press and HOLD the Program Button for about 3
seconds. There will be a 3 second delay after turning the hearing aid on
until amplification begins. This allows you some time to set it in your ear
without feedback issues.
9 10
Adjust your volume level by simply rotating the volume dial
up or down.
To increase the volume, turn the volume control up (+).
To decrease the volume, turn the volume control down (-).
NOTE: Before wearing the hearing aid, we recommend turning your hearing
aid ON and setting the volume at a low or comfortable (not loud) setting to
reduce or limit feedback during placement.
1. Place your hearing aid over the top of your ear.
2. Hold the tube close to the dome with your thumb and forefinger. With gentle
pressure, insert the dome into your ear canal until the tube sits flush against the
side of your head. The dome should fit in your ear canal snugly, but not tight.
3. Using your index finger, tuck the retention lock into the edge of the bowl of your
ear just above the area of the ear lobe. If your hearing aid fits well without use
of the retention lock, you may elect to remove it with a pair of scissors.

5. Do I have to turn off my hearing aid before I put it in the charger?
No. When you place your hearing aid into the charging base, it will turn
OFF automatically to allow for a faster charging cycle. We recommend
that you turn hearing aid OFF when not in use to prevent unwanted
battery drain and/or feedback noise
6. How do I best preserve product and battery performance?
To best preserve your hearing aid and battery, we recommend that you
always let it charge overnight and turn it off or leave it in the charging
base when not in use. Because a sensor stops the charging process
once the battery is full, there is no risk of battery degradation if the
hearing aid is kept in the charging base.
7 . Can I replace the built-in battery?
No, this is a custom battery that can only be replaced by the
manufacturer. For battery replacement service, contact Hearing Assist.
13 14
1. How do I charge my hearing aid?
Connect the charging base with the included Micro-USB cable.
Use the AC Adaptor to plug into a wall outlet (120/220 volt
compatible), or connect to any USB port on a plugged in computer
or travel charger to charge the hearing aid.
2. How long will it take for my hearing aid to charge?
It takes approximately 3-3.5 hours to fully charge your hearing aid.
3. How long will my fully charged hearing aid work until the next charge?
In most environments, the fully charged hearing aid will work up to
20 hours. If the surroundings are loud, the hearing aid may require
more power to filter out unwanted sounds, resulting in a slightly
smaller usage duration.
4. How do I know when my hearing aid is fully charged?
LED light indicator turns GREEN when fully charged.
LED light indicator stays BLUE during the charging process.

8. How do I know when the battery is going to run out?
There is a light audible beep that will indicate low battery function.
Performance of the Hearing Aid will also be affected until recharged.

Sound tube cleaning and care
Care of the sound tube
Use a soft cloth to remove any dirt and moisture after each use. The provided
GREEN cleaning line and brush is for removing debris / wax built-up inside the
sound tube and dome.
Replacement and cleaning of sound tube
1. To replace - rotate the sound tube counter-clockwise from the hearing
instrument case until loosened for removal. Replacement tubes and domes are
available from Hearing Assist.
2. To clean - insert the GREEN cleaning line through the threaded end of the tube,
push the cleaning line all the way through the tubing until the tip of the GREEN
cleaning line comes through the end of the dome.
Whistling is common in hearing aids and is also known as 'feedback'. This
phenomenon is caused by amplified sound leaving the ear, being received
back into the microphone and being re-amplified. The following tips will help
reduce the effect of whistling/feedback noise:
1. Lower the volume.
Keep volume at a lower setting before inserting the instrument in your ear.
2. Secure the positioning of the dome within the ear.
Feedback/whistling noise will stop when the hearing aid is securely fitted/
sealed in the ear with the best fitting dome size.
3. Clear the ear canal of wax or debris.
Seek guidance from your physician for excessive wax built-up.
4. Replace the dome or tube.
Change to a new dome with a better fitting size.
Make sure the ear tubeis not broken or torn.

DO NOT use water, harsh chemicals, strong cleaners or other fluids to clean
your hearing aid
DO NOT leave your hearing aid in the direct sun or in areas where the
temperature can rise over 60°C / 140°F for extended periods of time.
ALWAYS handle your hearing aid with care; it’s important to prevent your
hearing aid from dropping on hard surfacessuch as counter tops,
tablesor floors.
Cleaning care and precautions
Keep your hearing aid clean and dry. Use a soft cloth to remove any body oil
or moisture from the hearing aid housing. Use the provided cleaning tools to
clean wax build-up. If the hearing aid is subject to a lot of perspiration, we
recommend turning it OFF and putting it into a dry box at least once a week
to reduce moisture-build up. These particular hearing aid boxes can be
bought online or at any local pharmacy.
3. To reassemble the sound tube, simply reverse the removal process by
tightening the tubeand the hearing aid connector with a clockwise motion
until the two flat surfaces are flush together.

Good health practice requires that a person with a hearing loss have a medical
evaluation by a licensed physician (preferably a physician who specializes in
diseases of the ear) before purchasing a hearing aid. Licensed physicians who
specialize in diseases of the ear are often referred to as otolaryngologists,
otologists or otorhinolaryngologists.The purpose of medical evaluation is to
assure that all medically treatable conditions that may affect hearing are identified
and treated before the hearing aid is purchased.
Following the medical evaluation, the physician will give you a written statement
that states that your hearing loss has been medically evaluated and that you may
be considered a candidate for a hearing aid. The physician will refer you to a
Hearing Healthcare Professional for a hearing aid evaluation.
The audiologist or hearing aid dispenser will conduct a hearing aid evaluation to
assess your ability to hear with and without a hearing aid. The hearing aid
evaluation will enable the healthcare provider to select and fit a hearing aid
to your individual needs.

Technical Specifications

Notice to Hearing Healthcare Providers
A hearing aid dispenser should advise a prospective hearing aid user to consult
promptly with a licensed physician (preferably an ear specialist) before dispensing
a hearing aid. If the hearing aid dispenser determines through inquiry, actual
observation, or review of any other available information concerning the
prospective user, that the prospective user has any of the following conditions,
then consult a physician.
If you have reservations about your ability to adapt to amplification, you should
inquire about the availability of a trial/rental or purchase-option program. Many
Hearing Healthcare Professionals now offer programs that permit you to wear a
hearing aid for a period of time for a nominal fee after which you may decide if
you want to purchase the hearing aid.
Stop Using Hearing Aids and Consult a Physician if:
* Hearing in one or both ears worsened.
*Your ear becomes occluded with excessive ear wax.
*Hearing does not improve while using the provided hearing aid.
*You develop an infection in your ear or ear canal.
* Skin irritation develops in or around your ear canal.
* Visible congenital or traumatic deformity of the ear.
* Unilateral hearing loss of sudden or recent onset within the previous 90 days.
* History of active drainage from the ear within the previous 90 days.
* Audiometric air-bone gap equal to or greater than 15 decibels at 500 hertz (Hz),
1000Hz, and 2000 Hz.
* History of sudden or rapidly progressive hearing loss within the previous 90 days.
* Visible evidence of significant cerumen accumulation or a foreign body in the ear
canal.
* Acute or chronic dizziness.
* Pain or discomfort in the ear.

Children With Hearing Loss
In addition to seeing a physician for a medical evaluation, a child with a hearing
loss should be directed to an audiologist for evaluation and rehabilitation. Hearing
loss may cause problems in language development, educational growth, and
social growth of a child. Training and experience qualify an audiologist to assist in
the evaluation and rehabilitation of a child with a hearing loss. This hearing aid is
not suitable for use by anyone under the age of 18.
Special care should be exercised in selecting and fitting a hearing aid whose
maximum sound pressure level exceeds 132 decibels because there may be
risk of impairing the remaining hearing of the hearing aid user.
A hearing aid will not restore normal hearing and will not prevent or improve a
hearing impairment resulting from organic conditions. In most cases infrequent
use of a hearing aid does not permit a user to attain full benefit from it. The use
of hearing aid(s) is only part of hearing rehabilitation and may need to be
supplemented by auditory training and instruction in lip reading.
