The information contained in this manual is important for safe
and reliable operation. Anyone who will handle, maintain, store,
or dispose of your hearing aid should read this document.

The Limited Warranty document is enclosed together in the package. Keep it in a secure place. Make sure that it is
properly completed, signed with the authorized dispenser’s name, and filled in with date of original purchase, name
of dispenser and other important information.

The difference among the three models (WH-416KZ, WH-412LZ, WH-409MZ) is only additional installed circuit as
described in Page 37 of this document; otherwise the same.

Carefully read and thoroughly understand this entire document before attempting to set up and operate the hearing aid.
Failure to follow the operating instructions may result in poor performance of the hearing aid or even cause permanent
damage to the user. Keep this document for future reference. If you have any questions, consult the dispenser where
you purchased your hearing aid.
