Modifying xReceiver wire to improve t
In some cases, you might nd that the
wire of the xReceiver unit does not lie
close to the side of the head or follow
the shape of the ear.
First, ensure the selected dome and
xReceiver unit sizes are appropriate
(see following pages).
If a dierent xReceiver tube does not
t better, you may need to modify the
curvature (bend) slightly using the
steps outlined below.
1. Remove the xReceiver unit from the
hearing instrument.
2. Heat the tube carefully with a hairdryer at a low
setting for a few seconds.
3. Do not use excessive heat to avoid damage to the
electrical components.
4. Bend the tubing into the desired shape and hold
until it has cooled o. Once completely cooled, the
tube will maintain its new shape.
4. Choose the sightline (0-1-2-3) on
the measurement tool that is most
parallel with the top of the opening
of the ear canal. In this example,
the sightline marked 1 would be the most accurate
choice.
5. Make a note of the sightline chosen and then
repeat steps 1-4 on the opposite ear for a binaural
tting.
Note: It is important to measure the opposite ear for a binaural
tting since right and le ear sizes can vary and thus, require
dierent wire lengths.
