Remove the sensor strips

1. Remove the sensor strips from the patient's face, starting with the end under the
eye. Alternatively, ask the patient to remove the sensor strips.
2. Dispose of the sensor strips in accordance with local guidelines.
At the beginning of each test, the device automatically
recalibrates the light intensity and color, during which time
the patient will see brief red, green, and blue flashes. This
process takes about one second. If recalibration is
unsuccessful, an "Unable to calibrate" or "Excessive
ambient light" error will display. See "Troubleshooting" for
suggestions to resolve this issue.
