Using the Monitor

When an O M sensor is attached to the monitor and applied to a
XI AX
patient, the monitor may lose a pulse signal. If a pulse signal is lost,
an alarm sounds and a poor signal condition message displays on the
monitor screen. At this point, the monitor displays [
(3 dashes / 3 dashes) and remains in the Pulse Search Mode for five
seconds before displaying the poor signal condition screen. The poor
signal condition screen is part of the N-600x's Sensor Messages
feature. For more information about O
OXIMAX Sensor Messages on page 69.
