Tips for optimal wireless fitting
Let the battery breathe/oxygenize before inserting
When performing a wireless fitting, always use new batteries. The most common type of hearing
instrument batteries are zinc-air. These types of batteries are activated by the oxygen in the air. By
removing the small sticker from the battery, oxygen activates the battery. Because oxygen must pass
through fine holes and a filter, the oxygen is absorbed slowly.
Therefore, it is important to wait 2 full minutes after removing the battery sticker and before inserting the
battery and closing the battery door on the hearing instrument. If inserted prematurely, the battery may
not absorb enough oxygen to properly power the hearing instrument.
Always open/close the battery door to connect
