Place the coil on your head. The coil magnet should hold it in place2.
over your implant.
You may find it easier to turn on your processor before placing it on
your ear. To turn it on, press and hold the lower button for at least one
second until you see short flashes of green. The number of flashes you
see corresponds to the number of your current program (e.g. if your
current program is program 2, you see two green flashes).
When you turn on your processor before placing it on your ear, you may
see flashes of orange. This indicates that the coil is not placed on your
head. If the flashes do not stop even after placing the coil on your head,
see Understanding indicator lights for more information.
