D Coil
Fig. 20 D Coil
Important
Depending on the type of implant, two variants of magnets (i.e. magnet inserts) are
available for the D Coil. These two variants differ in magnet polarisation. The type of
implant is stated on your Patient Identification Card.
For recipients implanted with a SYNCHRONY implant, the magnet insert
must contain triangles as shown in Fig. 23.
For recipients implanted with any other type of implant (CONCERTO,
SONATA, etc.), the magnet insert must contain circles as shown in
Fig. 24.
It is essential that, based on the type of implant, the correct variant of magnet is used!
If the wrong variant of magnet is inserted, the coil may still be held in place over the
implant. However, due to different polarisation of the magnets, a slight dislocation
between the implant and coil will occur which may result in improper communication
between implant and coil.
The D Coil allows changing the magnet insert in the centre of the coil to adjust the
magnet strength to your needs.
To change the magnet, proceed as follows:
1. To remove the magnet insert, turn it to either side until it disengages and lift it off
(Fig. 21).
2. To attach a new magnet insert, place it over the recess in the coil (Fig. 22.1). It
should glide into the recess easily.
3. Turn the cover until it engages (Fig. 22.2). You will feel a slight resistance when the
cover snaps in place.
