Congratulations on your purchase!
With a little practice, you will soon be on your
way to better hearing. The amplification of
sound provided by your hearing instruments
was adjusted by your hearing care provider
to the needs of your individual hearing loss.

Please read the entire contents of this booklet before
using your hearing instruments. It contains instructions
and important information about the use and handling
of your hearing instruments and batteries. With proper
use and care, your hearing instruments will improve
your connection with the world around you.

General Warnings and Safety Guidelines

Hearing instruments and batteries can be dangerous
if swallowed or improperly used. Such actions
can result in severe injury, permanent hearing loss
or even fatality.

Familiarize yourself completely with the following
general warnings and safety guidelines before using
your hearing instruments.

Hazard warnings

Never allow others to wear your hearing

instruments. They are adjusted for your
hearing requirements and may permanently
damage another person’s hearing.

Avoid wearing your hearing instrument while

playing contact sports (e.g., rugby, football, etc.),
since a strike to the ear could be harmful.

Hearing instruments, their parts and batteries

should be kept out of reach of infants, children,
and anyone who might swallow these items
or otherwise cause themselves injury.

Take care when changing and discarding

batteries to keep them out of reach of infants,
children, persons of mental incapacity or pets.

CHARM · USER GUIDE BTE AND miniBTE

Clean your hearing instruments and their

parts on a regular basis as recommended.
Micro-organisms from unclean instruments
may cause skin irritations.

Be careful with leaking battery liquid, as it is

a hazardous substance.

Never attempt to recharge non-rechargeable

batteries.

Be aware of the possibility that your hearing

instruments may stop functioning without notice.

11

Keep this in mind while you circulate in traffic
or otherwise depend on warning sounds.

Remove your instruments before applying

aftershave, hairspray, oils, perfume, mosquito
repellent, lotions, etc. Allow the product
to dry before wearing your instruments.

Traffic or other warning sounds may be reduced

in level by a directional microphone when
these sounds are coming from behind you.

12

SONIC · CHARM

Warnings to hearing care provider and patient

Special care should be taken when fitting and
using a hearing instrument with maximum
sound pressure capability in excess of 132 dB SPL
(IEC 60318-4) since there may be a risk of
impairing the remaining hearing of the patient.

When the DAI is connected to AC-powered

equipment, this equipment must comply with
IEC-60601-1 or equivalent safety standards.

CHARM · USER GUIDE BTE AND miniBTE

13

Safety information

· Hearing instruments should be used only as directed
and adjusted by your trained hearing care provider.
Misuse or improper adjustments can result in sudden
and permanent hearing loss.

· Never put your hearing instrument or batteries
in your mouth, as they could easily be swallowed

· Keep batteries away from medications, since they
can easily be mistaken for pills

· In the event that a battery or hearing instrument
is swallowed, see a doctor immediately

· Be aware that use of a hearing instrument may cause
excess earwax to build up in the ear canal which may
require removal by a trained medical professional

· Consult your physician if excessive earwax, skin
irritation, or a foreign object prevents you from
wearing your hearing instrument

· An Earmold is a custom-made product. If you
experience discomfort or irritation of your ear,
please see your hearing care provider immediately
for modification of the Earmold.

· In rare cases, a hearing instrument or Earmold may
cause a discharge from the ear or allergic reaction.
See a physician immediately if these conditions occur.

14

SONIC · CHARM

· Never insert cleaning tools into the microphone inlet
or deeply into the sound outlet. This could damage
the hearing instruments.

· Do not expose hearing instruments to extreme
heat by leaving them in the car, near a radiator, etc.

· Avoid exposing your instruments to water and
moisture i.e., steambaths, showers, heavy rain, etc.

· Do not wear your hearing instrument while
swimming, snorkeling or diving, as it is not designed
for such activities

· Do not immerse your hearing instrument in water
or other liquids

· Never attempt to dry your instruments with
a hair dryer, microwave oven, etc.

· It is recommended to remove your hearing
instruments before sleeping

· Protect your instruments by keeping them in the case
when you are not wearing them

CHARM · USER GUIDE BTE AND miniBTE

15

Hearing Expectations

Set appropriate expectations

It is important that you have the right expectations
regarding your hearing instruments. Hearing
instruments can help you hear and understand better,
but they are not a cure for hearing loss.

People whose expectations are too high (“I thought
they would make my hearing normal”) are likely to be
disappointed and may give up.

Hearing instruments can:

· Help you hear and understand better in most
situations

· Allow you to participate more in group situations
and meetings

Hearing instruments cannot:

· Give you normal hearing

Hearing instruments may not:

· Let you hear very soft sounds

· Block ALL background noises – especially in noisy
situations. Even people without hearing loss
may have difficulty hearing in the presence of
background noise.

16

SONIC · CHARM

Be patient

Unlike with eyeglasses which correct your vision
as soon as you first put them on, with hearing
instruments you will need some time to adjust.

It may take several weeks or months to completely
adjust to your hearing instruments, so try to be patient.
Initially, try different listening situations, such as
one-on-one conversations with family and friends,
and conversations with two or three people at home
or in quiet settings. Also, try having conversations
in noisier places like parties, restaurants, meetings,
and outdoors.

Do not forget that some situations are simply too noisy
in general – even for people without hearing loss.
So, do not get discouraged.

CHARM · USER GUIDE BTE AND miniBTE

17

Consistent use of your hearing instrument is strongly
recommended. In most cases, infrequent use does
not allow you to obtain the full benefit from your device.

The use of a hearing instrument is only a part
of total hearing rehabilitation, and may need to be
supplemented by auditory training and instruction
in lipreading.

Turning Your Hearing Instrument
OFF and ON

To prolong battery life, turn off your hearing instrument
when not in use. Before turning your hearing
instrument off, wipe away any moisture with a soft
cloth.

Charm BTE

To turn your BTE hearing instrument off, put your
fingernail into the battery door grip and open the
battery door slightly until you feel a firm stopping
point. Only a small portion of the battery is visible,
which keeps the battery from falling out completely.
To turn the hearing instrument back on, fully close
the battery door.

ON OFF

CHARM · USER GUIDE BTE AND miniBTE

23

Charm miniBTE

To turn your miniBTE hearing instrument off, open
the battery door slightly by pushing on the edge
of the seam. To turn it back on, fully close the battery
door.

ON OFF

Your hearing instrument may be programmed to alert
you with a beep when it is turned on. Your hearing
care provider will tell you if this feature is enabled.
Your hearing instrument may also have a “power on”
delay. This allows you to insert the device before it
is fully active.

24

SONIC · CHARM

Putting On Your Hearing Instrument –
Thin Tube

· First, position the hearing instrument
over the top of your ear

· Grasp the bend of the Thin
Tube and gently push the Dome
into your ear canal until
the tube rests against the side
of your head. When the Dome

you should not be able to see
the Thin Tube sticking out
when you look directly into
a mirror. If the Thin Tube
is sticking out from your ear,
insert the Dome further.

· Use your finger to push
the retention lock comfortably
into the bowl of your ear

CHARM · USER GUIDE BTE AND miniBTE

25

Taking Off Your Hearing Instrument –
Thin Tube

· To remove your hearing instrument, hold
the Thin Tube and gently pull the Dome out of
your ear canal

· Lift the hearing instrument case from behind your ear

· Open the battery compartment to turn off the device

Note!

lobe with your other hand may help.
A slight twist may be needed
to fit the Earmold in your ear.

· When the Earmold is in your ear,
place the hearing instrument
behind the top part of your ear.
Do the same with the left hearing
instrument and Earmold.

CHARM · USER GUIDE BTE AND miniBTE

27

Taking Off Your Hearing Instrument –
Earhook

To take your hearing instrument off, hold the Earmold
with your thumb and first finger. Gently pull it out of
your ear canal.

A slight twist may be needed to remove it. Do not
pull on the tube, as it may come out of the Earmold.

the hearing instrument from behind your ear.

Note!

Even though they look the same, hearing
instruments are programmed to fit a specific
ear (right or left). Make sure the correct
hearing instrument is used with the correct
Earmold. Refer to the right and left instrument
markers on pages 18 and 20.

Changing the Volume

Your hearing instruments are programmed to be
at a comfortable volume level for your hearing loss.
They are designed to automatically adjust to changes
in the sound environment. You should only need
to make small volume changes to get natural and
comfortable sound.

If you have purchased an optional RC-P Remote Control
or SoundGate accessory, you can use it to make
small volume changes to get a natural and comfortable
sound. Please see pages 56 and 57 for further
instructions.

Note!

If the default volume of your hearing
instrument is too loud or soft, your hearing
care provider may need to make changes
to your listening program.

Note!

Your hearing instruments automatically return
to a pre-set loudness level when they are
powered on, when the battery is low, or when
the program is changed. If you find that you
frequently need to turn the volume up or down,
your hearing care provider may need to adjust
your settings.

CHARM · USER GUIDE BTE AND miniBTE

31

Charm BTE only

Charm BTE has a Volume Control that allows you to
adjust the volume as needed. Rotate the Volume
Control up to turn up the volume. If you need to lower
the volume, slowly turn the Volume Control down.
Your hearing instrument may play a series of beeps
when you have reached the maximum or minimum

instruments.

CHARM · USER GUIDE BTE AND miniBTE

37

Changing the Battery

When the battery power level is low, your hearing
instrument will beep at regular intervals. You should
be prepared to replace the battery. The time until
the hearing instrument stops working depends on
the battery type and manufacturer. Mercury-free
batteries generally cause earlier warning beeps.

Change batteries regularly

When your battery needs to be changed, you will hear
three beeps: a low tone, followed by a high tone and
another low tone. The exact battery life you experience
may vary, but you should expect approximately
200 hours of total hearing instrument use per battery.

Battery type

Stainless steel zinc-air batteries are recommended.
Your hearing instrument uses a #13A battery.

Note!

Never force the battery door open or closed.

builds up on the Dome. Spare Domes can be obtained
from your hearing care provider.

· Remove the old Dome by pulling it off the end
of the Thin Tube

· With clean fingers, push a new Dome as far
as possible onto the Thin Tube. When attached
correctly, the Dome should touch the plastic
ring around the Thin Tube.

Note!

If the Dome is not securely attached to
the Thin Tube, it could fall off in your ear canal.
If this happens, please see your medical
provider.

Exchanging the Thin Tube system

If the Thin Tube becomes discolored, stiff or brittle,
it should be replaced.

· Hold the instrument by the Thin Tube Adapter
and grasp the Thin Tube close to the connector

· Pull firmly to remove the old Thin Tube

· Attach the new Thin Tube by pushing it firmly into
the connector

Your hearing instruments contain electronic
components subject to the Directive 2002/96/EC on
waste electrical and electronic equipment (WEEE).

Product Approval, Markings
and Compliance

All Sonic hearing instruments comply with international
standards concerning electromagnetic compatibility.
Due to the limited space available on the hearing
instruments, all relevant approval markings are found
in this document.

Electromagnetic interference

Your hearing instrument has been thoroughly tested
for electromagnetic interference. However, some
products may emit electromagnetic energy causing
unforeseen interference with hearing instruments.
Examples include induction cooking appliances,
shop alarm systems, mobile phones, fax machines,
personal computers, X-rays, CT scans, etc.

Even though your hearing instruments are designed
to comply with the most stringent international
standards of electromagnetic compatibility, they
may emit electromagnetic energy that can cause
interference with other devices.

Your hearing instruments contain a radio transmitter
using short range magnetic induction technology
working at 3.84 MHz. The magnetic field strength
of the transmitter is < -42 dBμA /m @ 10 m.

CHARM · USER GUIDE BTE AND miniBTE

61

The electromagnetic emission from the radio system
is well below international limits for human exposure.
By comparison, the electromagnetic energy of the
hearing instruments is lower than that generated
by household items such as halogen lamps, computer
monitors, dishwashers etc.

Protection against harmful ingress of water
and particulate matter

The enclosures of the device fulfill the requirements
of class IP57 according to EN 60529:1991/A1:2000.

Cell Phone and Hearing Instrument
Compatibility

Some hearing instrument users have reported
a buzzing sound in their devices when they are
using cell phones, indicating that the cell phone
and hearing instrument may not be compatible.

The compatibility of a particular hearing instrument
and cell phone can be predicted by adding the rating
for the hearing instrument immunity to the rating
for the cell phone emissions (ANSI C63.19-2006
American National Standard Methods of Measurement
of Compatibility between Wireless Communication
Devices and Hearing Aids).

For example, the sum of a hearing instrument with
a rating of 2 (M2/T2) and a telephone with a rating
of 3 (M3/T3) would result in a combined rating of

5. According to the standard, any combined rating
that equals at least 5 would provide “normal use”;
a combined rating of 6 or greater would indicate
“excellent performance.”

CHARM · USER GUIDE BTE AND miniBTE

63

The immunity of your Charm hearing instrument is at
least M2 and M2/T2 for miniBTE and BTE respectively.

The equipment performance measurements,
categories and system classifications are based
upon the best information available but Sonic
cannot guarantee that all users will be satisfied.

Note!

The performance of individual hearing
instruments may vary with individual
cell phones. Please try this hearing
instrument with your cell phone or, if you
are purchasing a new phone, be sure
to try it with your hearing instrument prior
to purchase. For additional guidance,
please ask your cell phone provider
for the booklet entitled “Hearing Aid
Compatibility with Digital Wireless Cell
Phones.“

Warranty and Repairs

Your hearing instruments have a limited warranty,
covering defects in materials and workmanship.
This warranty covers the hearing instruments
themselves, but not accessories such as batteries,
tubing, Domes, Earmolds, etc.

This warranty is void if a defect is the result
of misuse or mistreatment. The warranty is also void
if the hearing instruments have been repaired
by non-authorized service personnel.

Please review the warranty with your hearing care
provider and make sure that your warranty card is
completed correctly.

Note!

Your hearing care provider may charge
a service fee for processing warranty repairs.

Information for the Hearing Care Provider

A hearing care provider should advise a prospective
hearing instrument user to consult with a licensed
physician (preferably an ear specialist) promptly,
before dispensing a hearing instrument, if the hearing
care provider 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:

· Visible congenital or traumatic deformity
of the external or middle ear

· History of active drainage from the ear within
the previous 90 days

· History of sudden or rapidly progressive hearing
loss within the previous 90 days

· Acute or chronic dizziness or vertigo

· Unilateral hearing loss of a sudden or recent
onset within the previous 90 days

· Audiometric air-bone gap equal to or greater than
15 decibels at 500 hertz (Hz), 1000 Hz, and 2000 Hz

· Visible evidence of significant cerumen accumulation
or a foreign body in the ear canal

· Pain or discomfort in the ear

CHARM · USER GUIDE BTE AND miniBTE

Warning to hearing care provider and patient

Special care should be exercised in selecting
and fitting a hearing instrument whose maximum
sound pressure level exceeds 132 decibels due
to the fact that there may be risk of impairing the
remaining hearing of the hearing instrument user.

Children with hearing loss

A child with a hearing loss should be directed
to a physician for medical evaluation and to other
professionals for evaluation and rehabilitation since

71

hearing loss may cause problems with language
development and the educational and social growth
of a child.
