The fuel cell powers the black calibration needle in the oxygen
concentration meter. The cell has an average life of about one year,
depending on frequency of use. Difficulty in moving the black
calibration needle in the oxygen concentration meter is usually an
indication of an exhausted fuel cell.
CAUTION: Do not remove the fuel cell from the bag
until ready to use.
CAUTION: Wear safety glasses when handling the
fuel cell.
CAUTION: Avoid contact with the sensing surface.
CAUTION: The fuel cell contains lead, a chemical
known to cause cancer, birth defects, or other
reproductive harm.
CAUTION: Wash your hands thoroughly after
handling the fuel cell.
