Shaping the Receiver Unit
To ensure the hearing device correctly fits the ear, it may
be necessary to manipulate the Receiver. This is
especially true if the Receiver wire is too short and the
client reports that the earpiece tends to slip out or it
cannot be inserted deep enough in the ear canal.
The first step is to try another dome size. Sometimes a
smaller dome size will allow the Receiver unit to be placed
further into the canal.
If the wire is still not flush, you can change the curve of the
Receiver wire by straightening it a little or changing the
insertion depth. This is not a difficult procedure and the
following steps are important to avoid damaging the
Receiver 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 keep shape until wire
is cooled off.
• Do not use excessive heat and do not exceed 130°C.
Lengthening the Receiver
• To add length to the Receiver straighten the S portion
of the Receiver wire as marked.
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
Receiver insertion.
