If the hearing instrument is too quiet
Most likely, you need to insert a new battery. If it is still too quiet, clean the instrument or the ear mould and hearing tube, following the directions in the chapter “Notes for cleaning and care“.If neither a new battery nor cleaning helps, as a precaution you should ask your hearing instrument specialist to test your hearing again.
If the hearing instrument does not work at all Is the instrument turned on? Is the battery compartment completely closed? Is the battery inserted correctly? Is it possible that the battery is dead?
If none of these hints help, you should visit your All hearing instrument specialist.
