Adjusting Gains (Practitioner Only)
On the right side of the Signals screen there are sliding selection tools for
each electrode. The gains of all active electrodes can be set to a value in the
range of 1 to 7. To change the gains, drag the slider button left or right to
adjust the gain for each electrode.

Not all electrodes will be activated during every movement. However, the
gain must be high enough that you will see at least a small signal on each
electrode during one of the movement patterns. If this is not the case, then
the gain has to be increased or the position of the electrode needs to be
changed.
If the gain is modified, the new gain is sent automatically to the Sense
Controller and the changes are immediately reflected in the signal viewer.
However, to save these gains permanently, you must press the "Save
Settings" button, which becomes red after any gain is adjusted.
Recalibration is required after changing the gains and before use of the
prosthesis.
Electrode Status (Practitioner Only)
Pattern recognition works best with 8 electrodes, but the system will still
work with less. A minimum of 3 must be connected. If an electrode is
producing erroneous signals (or not producing signals at all), you can turn it
off by clicking on the colored button next to it. To turn it back on, click on the
button again. A description of the button status is provided below.
