My hearing was so bad that I felt left out

now that I haven’t heard in years.”

STEP 3STEP 2

OFF

ON

The VO LT uses a Volume Dial with a built in
on/off control (like a radio).

• To turn V OLT ON, turn Volume Dial upward,
past the click.

• To turn V OLT OFF, turn Volume Dial
downward, past 0 until you feel a click.

IMPORTANT: When VO LT is turned ON, it will

take a few seconds to begin amplifying sound.

Please raise the volume SLOWLY to avoid a
sudden blast of sound.

WARNING: Whistling may be heard if VOLT is

turned ON but NOT positioned securely in your

ear. This is normal. Once the ComfortTIP is

properly inserted in your ear, whistling will stop.

Follow these tips for optimal performance:

• Avoid physical shock, such as dropping on the oor.

• For maximum battery life, charge

VOLT until blue light turns

green with each charge.

• Store in a cool dry place when not in use, such as a

hearing aid dehumidier.

• Do not let your VO LT get wet.

• Do not use hair spray or a hair dryer while wearing your V OLT .

• Do not expose your VOLT to excess moisture or heat.

USING THE TELEPHONE

Please note: The speaker function on your phone also works well with your VO LT .

Use Program 1 (one) or 2 (two) when using
the phone. You may need to make slight
adjustments to the volume of either your

VO LT or phone. If whistling occurs, try

different positions with the phone’s audio

TROUBLESHOOTING

23

1. Sound is distorted or intermittent.

• Rotate Volume Dial (on/off control)

back and forth, in case dust or lint
has collected in the controls.

• Trapped moisture may be

distorting the amplied sounds.

Consider using a hearing aid

dehumidier overnight.

• Lower the volume.

• Turn

VO LT OFF. Charge until

blue light turns green and turn

VO LT back ON.

• Check Tubing/Tip for wax or
debris that may be blocking
sound. Clean Tubing/Tip.
Replace Tubing/Tip if they
appear worn.

For optimal performance, ComfortTIP

™

and Tubing should be replaced
every three months. Replacements and additional cleaning accessories
can be ordered at: www.MDHearingAid.com.

24

2. Instrument makes a whistling sound.

• Whistling (feedback) occurs when

amplied sound returns to the
microphone and is re-amplied.

• Most hearing aids whistle when
not inserted properly. Try
reinserting the ComfortTIP™

into ear canal so it ts better.

• Lower the volume.

• If whistling occurs when you
raise the volume, try using a
Closed ComfortTIP.

• If whistling occurs after trying
a Closed ComfortTIP, you might
require more gain (volume) and
should try the High Volume Kit
(see page 18).

• Clean any wax or debris from
Tubing/Tip and/or ear canal.
Whistling will disappear when
the condition is corrected.

Please note: When an object (hand, hood, person, chair, wall... etc.)
comes close to your ear while wearing hearing aids, you may experience
whistling. This is normal for all microphones when temporarily obstructed,
not just microphones in hearing aids.

25

Tube Cleaning Tips: Remove Tubing from VO LT Body. Thread Cleaning Tool Wire

through Tubing ve-six times starting at the triangular Tubing Base. Then wipe
debris from Tubing/Tip and reattach Tubing to VOLT Body.

3. Instrument has a weak or no sound.

• Make sure your MDHearingAidVOLT
is turned ON.

• Rotate Volume Dial (on/off control)
back and forth, in case dust or lint
has collected in the controls.

• Make sure VOLT is fully charged.

• Remove Tubing from VOLT Body
and rotate Volume Dial to three. If it
whistles, your VOLT is working and
the Tubing/Tip needs to be cleaned
or replaced.

• If you are still having difculty,

please email us at

WARNING TO HEARING AID DISPENSERS

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:

• Visible congenital or traumatic
deformity of the 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.

• Pain or discomfort in the ear.

• Unilateral hearing loss of 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 signicant

cerumen accumulation or a
foreign body in the ear canal.

33

Stop using the MDHearingAidV OLT and consult a physician if:

• Hearing in one or both ears
worsens.

• Hearing does not improve while
using the VO LT.

• Skin irritation develops in or
around your ear canal.

• Your ear becomes occluded with
excessive ear wax.

• You develop an infection of your
ear or ear canal.

Special care should be exercised in selecting and tting 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 benet from it. The

use of hearing aids is only part of hearing rehabilitation and may need to be
supplemented by auditory training and instruction in lip reading.

34

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 a medical evaluation is
to assure that all medically treatable conditions that may affect hearing are

identied 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 an audiologist or a hearing aid dispenser, as appropriate,
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 audiologist or dispenser to select and t a hearing

aid to your individual needs.

IMPORTANT NOTICE FOR PROSPECTIVE USERS

35

If you have reservations about your ability to adapt to amplication, you should

inquire about the availability of a trial/rental or purchase/option program. Many
hearing aid dispensers now offer programs that permit you to wear a hearing aid
for a period of time for a fee after which you may decide if you want to purchase
the hearing aid.

Federal law restricts the sale of hearing aids to those individuals who have
obtained a medical evaluation from a licensed physician. Federal law permits a
fully informed adult to sign a waiver statement declining the medical evaluation
for religious or personal beliefs that preclude consultation with a physician. The
exercise of such a waiver (without prior consultation by an ear specialist) is not
in your best health interest and its use is strongly discouraged.

Children with hearing loss

This product is not for use by anyone under 18 years of age. 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. An audiologist is qualied by training and experience to assist in the

evaluation and rehabilitation of a child with a hearing loss.
