First check whether the volume control is working, and whether you can make it louder. To do this, take the hearing aid in your hand and clasp it. The hearing aid should now emit a whistling noise. Check the hearing tube and earpiece for earwax or moisture and clean if necessary.
Check whether the battery is correctly inserted and fitted in correctly. If there is no improvement, replace the battery. If the problem persists, contact your
local bloom hearing specialists store by calling 1800 554 968 or booking a
