The fitting goal is to provide a comfortable and secure fit with a minimal amount of
occlusion, while providing a pleasing appearance.
The ideal device placement is to position the faceplate slightly past the tragus into the
canal. The body of the device should allow gaps between its shell and the canal wall. The
tip should ideally not come in contact with the canal wall. The faceplate should not be
visible from the front and may be slightly visible from the side (fig 1).
Step 1:
Check to be sure the ear canal is large enough to hold the body of the
APT-D (see Inserting APT-D into Ear below). If the canal is too small,
the APT-D is not an appropriate device for this client.
Step 2:
Medium D-Ring
(see Attaching D-Ring to APT-D Body below).
Step 3:
Insert the APT-D into ear (see Inserting APT-D into Ear below). If the D-
Ring will not fit or is deformed when it is in the ear then go to step 7
Small D-Ring.

- Page 9 The APT-D is designed for a shallow location in the ear canal, so wax is typically less of an issue than with traditional ITEs. Still, a wax guard is used to insure against wax damage to the receiver. A wax guard tool is used for the removal and insertion of the wax guards.
