Choice of é-tip: The é-tip is available in four sizes. It is
important to choose the correct é-tip in order to en-
sure a good and comfortable fit. The é-tip must be po-
sitioned comfortably in the ear canal. The é-tip is re-
placed by pulling the é-tip off the rest of the élan ear-
set. A new é-tip is then placed on the élan ear-set. It is
very important to ensure that the é-tip is firmly secured.
