The numerical displays will flash once each second if the 920
determines that a battery low condition exists. Replace all six
batteries immediately.

If the 920 determines that a sensor fault exists (sensor disconnect,
sensor failure, or sensor dislodgment), a dash (-) appears in the
left-most digit of the SpO display. The readings that are being

displayed will remain unchanged while the sensor fault exists. If the
sensor fault is not corrected, dashes will be displayed 10 seconds
after the minus sign appears.
