Step 2: Check the coil:
Disconnect the coil cable from the coil.
Confirm that the socket on the coil shows no signs of damage.
Reconnect the coil cable to the coil. Make sure the coil cable is
fully inserted into the socket on the coil.
If the socket on the coil is damaged, replace the coil.

processing unit are free of dirt and dust. Blow away any dirt or
dust.

Replace the microphone protectors if you notice degradation in
the sound quality, or if the protectors look dirty.

Confirm that the accessory socket is free of dirt and dust. Blow
away any dirt or dust.

accessory cable is damaged, replace the cable.
If any part of your processor, coil or coil cable is physically damaged,
contact your clinician.
