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.
