Introduction
We would like to thank you for purchasing the
Panasonic Hearing Instrument WH-103JZ.
This hearing instrument helps optimize both intelligibility
and comprehension for the hearing impaired.
The type of hearing aid that will work best for you
depends on the type and severity of your hearing loss
and usage conditions. You will need to get a thorough
hearing evaluation and have your ears examined by an
ear specialist or an audiologist. They will suggest the
most appropriate type of hearing aid for you depending
on the type and degree of hearing loss. In order to get
the right hearing aid that will be tailored to meet your
individual needs and lifestyle, be sure to have your
hearing aid properly fitted and fine-tuned to your ears,
as an improper fit can cause discomfort and flexibility
issues, and even further damage to the ear.
It is important to keep in mind that hearing aids will not
restore normal hearing, nor will they halt the
progression of hearing loss. They are intended to
compensate for impaired hearing. They should be used
only for the purpose they are designed and directed.
Carefully read the instructions and make sure you fully
understand the operation of the hearing aid before
using it.

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:
1. Visible congenital or traumatic deformity of the ear.
2. History of active drainage from the ear within the previous 90 days.
3. History of sudden or rapidly progressive hearing loss within the previous 90 days.
4. Acute or chronic dizziness.
5. Unilateral hearing loss of sudden or recent onset within the previous 90 days.
6. Audiometric air-bone gap equal to or greater than 15 decibels at 500 hertz (Hz), 1,000 Hz, and
2,000 Hz.
7. Visible evidence of significant cerumen accumulation or a foreign body in the ear canal.
8. Pain or discomfort in the ear.

Hearing aids must be programmed and adjusted by the dispenser on an
individual basis. Inappropriate hearing aid setting may cause damage to the
ears of your customers.
If you have any questions about fitting, contact the Panasonic sales division below.

Before Use Important Notice for Prospective Hearing Aid Users
Important Notice for Prospective Hearing Aid Users
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 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 fit a hearing aid to your individual needs.
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 aid
dispensers 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.
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 is not in your
best health interest and its use is strongly discouraged.

Children with Hearing Loss

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 since hearing loss
may cause problem in language development and the educational and social growth of a
child. An audiologist is qualified by training and experience to assist in the evaluation and
rehabilitation of a child with a hearing loss.
