High ambient light sources such as surgical lights (especially those with a xenon
light source), bilirubin lamps, fluorescent lights, infrared heating lamps, and
direct sunlight can interfere with sensor performance. To prevent interference
from ambient light, ensure the recommended sensor is properly applied and
cover the sensor with opaque material.
