Dome size
Perform an otoscopic examination of your member’s ear canal. Based on the
examination, choose a dome size diameter and length suitable for the ear
canal. The dome should fit snugly and comfortably into the opening of the
member’s ear canal, shown in the figure, and help to retain the receiver inside.
*There are no coupling instructions for cShell as it is pre-assembled. Receiver with cShell can only be exchanged by the manufacturer.
