The coil connects the OPUS 2 speech processor with the implant. It sends both energy and the
coded acoustic signal through the skin to the implant.
A small magnet is located in the center of the coil to hold it in place on the head over the
implant package. The magnet strength can be adjusted by your audiologist or clinical staff to
meet your individual needs.
If you notice any signs of skin irritation around the coil, contact your clinic or CI center.
It is easiest to observe children when playing or in everyday situations to determine whether
the coil is properly attracted to the implant. If the coil falls off too easily, your child may
develop an aversion to wearing the coil. During the first months after surgery, you should regularly
check the skin under the coil for irritation. As the child grows, skin thickness will increase and the
magnetic attraction force will need to be adjusted by increasing the number of magnets. Your
audiologist can adjust the magnet strength of the coil.
The coil and speech processor are connected by the coil cable. You have to unplug the cable
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 cable is designed for maximum durability and flexibility, this part of the MED-EL
Cochlear Implant System is most likely to wear out.
If a cable fails, order a new one immediately.
Do not use the cable with devices other than the OPUS 2 speech processor.
