Thin Tube lengths
To ensure a secure fitting with maximum patient comfort, the proper
Thin Tube length should be selected for each patient before fitting a
Charm BTE or miniBTE. Sonic Thin Tubes come in four different lengths,
and a red (Right) or blue (Left) marker on the Thin Tube identifies
the orientation.

Determining the proper Thin Tube length
To determine which Thin Tube length is most appropriate for your patient,
use the fitting tool from your Sonic BTE Dispensing Kit.
Note! Right and left markings on the fitting tool indicate which
hand to use and which ear to measure. Four sightlines (0-1-2-3)
indicate the proper tubing length, according to the table above.

Fitting a Charm IIC
The IIC hearing instrument is designed to sit deep in the canal after
the first bend. Candidacy depends on the patient’s ear canal anatomy.
In order to determine if an IIC is possible for your patient, follow
the fitting guidelines and illustrations below.
Impression evaluation
The candidacy evaluation for an IIC hearing instrument requires a quality
ear impression that extends beyond the second bend of the ear canal.
The size and fit of the IIC is determined by the ear impression. Use the ear
impression tool to determine if the size and shape of the ear canal are
appropriate for an IIC.
The IIC hearing instrument can be built with the microphone on the side (A)
or on the top (B) of the faceplate. The ear impression tool can be used
to determine which configuration is most suitable for the given ear
impression.
Using the ear impression tool
1 Canal length
The length of the canal determines if there is enough room between the tip
of the instrument and the faceplate. To determine if the canal length is
sufficient, use the red line and measure from the tip of the ear impression
to the first (1) bend. In order to make the IIC invisible, the edge of the tool
should not reach the first bend.

2 Canal height
The height of the canal determines if there is enough space for the IIC
to pass through the canal to the final ear canal placement. The height
of the ear impression measured at a point between the first (1) and
second (2) bends must be larger than the pink line on the ear impression
tool.

3 Canal width
The width of the canal determines if the faceplate will fit past the first
bend. The width of the ear impression measured at a point after the first (1)
bend must be greater than the grey line on the ear impression tool.
The canal should be wider than the notch and not fit within the notch.
4 Canal shape
It is important to visually inspect the ear impression for proper canal
shape. An ear canal that widens at the end is not suitable for an IIC (C).
