Shaping The Speaker Unit - oticon Vigo Connect Fittings Manual

Shaping the Speaker Unit

If the speaker unit is too long, the amplifier will sit too low on
the ear and the microphones will not point in the right direc-
tion. Also, the wire will not follow the helix nicely behind the
ear.
If the speaker unit is too short, the speaker will be difficult to
place deep enough in the ear canal to get a secure hold, and
it may fall out. (It will feel unpleasant on the top of the ear).
If the wire is not flush with the skin, check that the insertion
depth is correct. You may need to use another dome size if
the speaker unit needs to move further in the ear canal.

• If the wire is still not flush, you might want to change
the curve of the speaker wire to either straighten it a little
or to change the insertion depth. This is not difficult, but
the following steps are important to avoid damaging
the speaker unit:
• Use a hair dryer or spectacle instrument at low heat
setting.
• Heat for a short time – a matter of seconds.
• Bend into desired shape and hold shape until wire
is cooled off.
• Do not use excessive heat and do not exceed 130°C.
"S" Curve
• To add length to the receiver, straighten out or elongate
the S portion of the speaker wire.

Bend into the Canal
• Adjust this bend to stop the wire from bowing out from
the side of the client's ear, or to increase the depth of
speaker insertion.
