COIL CABLE
The coil and audio processor control unit are connected by the coil cable. The coil cable must
be disconnected for maintenance purposes or if you want to replace the cable. It is not
necessary to disconnect the cable when changing the batteries.
Although the coil cable is designed for maximum durability and flexibility, this part of the
MED-EL Cochlear Implant System is the most likely to wear out.
If the coil cable fails, order a new one immediately.
IMPORTANT
Do not use the cable with devices other than the SONNET audio processor.
To replace the coil cable proceed as follows:
1. Make sure that the battery pack cover lock is in the unlocked position as shown in Fig.
7-1. When it is not in the unlocked position, use the screwdriver provided with your
SONNET kit to turn it counter-clockwise into the unlocked position.
2. Pull back the battery pack cover until you can see the whole labelling of the control unit
(see Fig. 3).
3. Grab the plug of the cable on the control unit side and gently pull the plug (1) out of its
socket in the control unit as shown in Fig. 14-1.
4. Grab the plug of the cable on the D Coil side and gently pull the plug (2) out of its socket
in the D Coil as shown in Fig. 14-2.
5. Plug a new coil cable into the D Coil.
6. Plug the other end (3) of the coil cable into the control unit as shown in Fig. 15. Make
sure that the cable plug is correctly positioned. The slanting edge must face down.
7. Make sure that the battery pack cover lock is in the unlocked position as shown in
Fig. 7–1. When it is not in the unlocked position, use the screwdriver provided with your
SONNET kit to turn it counter-clockwise into the unlocked position.
8. Slide the battery pack cover completely over the battery pack frame to switch on the
SONNET (see Fig. 4). Mind the correct orientation of the battery pack cover when sliding
it over the frame and do not use excessive force. The orientation is correct when the
air inlets on the battery pack cover are on the same side as the coil cable socket in the
control unit.
