and for the environment. Please note:

swallowed, as they can be harmful to your health.
3. Do not attempt to recharge batteries (Zinc Air) which are not specifically designated as recharge-
able because they may leak or explode.

5. Used batteries are harmful to the environment. Please dispose of them according to local regula-
tions or return them to your hearing care professional.

Hearing aid expectations
A hearing aid will not restore normal hearing and will not prevent or improve a hearing impairment
resulting from organic conditions. Consistent use of the hearing aid is recommended. In most cases,
infrequent use does not permit you to attain full benefit from it.
The use of a hearing aid is only part of hearing rehabilitation and may need to be supplemented by audi-
tory training and instructions in lip-reading.
