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 health 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 · CUSTOM USER GUIDE

Clean your hearing instruments and their parts

on a regular basis as recommended. Micro­organisms 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

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 in-the-ear hearing instrument 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 shell.

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

CHARM · CUSTOM USER GUIDE

13

· 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

SONIC · CHARM

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.

CHARM · CUSTOM USER GUIDE

15

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.

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.

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.

Some models allow you to adjust the volume
yourself, either with an optional Volume Control on
the instrument or with an optional remote control.

Volume Control (Optional for ITCD and ITED)

To increase the volume

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

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 · CUSTOM USER GUIDE

47

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.

SONIC · CHARM

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.”

The immunity of your Charm hearing instrument
is at least M2 or M2/T2 respectively.

CHARM · CUSTOM USER GUIDE

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
