Use a small brush to gently brush away any accumulated 
earwax from the hearing aid sound outlet.

Cleaning your 

hearing aid

It is important to regularly check the wax guard on the end of 
the hearing aid (white circle) for any build up of earwax. If any 
accumulated wax cannot be brushed away it is time to change the wax 
guard. The existing wax guard should be removed from the end of the 
hearing aid using the orange tool supplied originally with your order. 
New wax guards can then be attached into the hearing aid using the 
other side of the tool. Further instructions can be found on the cards 
carrying the new wax guards. New wax guard cards can be obtained 
from the website.
