Displays the battery charge remaining on the monitor. The
battery fuel gauge consists of four bars, each corresponding to
approximately 1.5 hours of operating time. All four bars are lit
when the battery is fully charged. No bars are lit when a low
battery condition exists. See Battery Fuel Gauge Indicator on
page 34.
Lights continuously when an audible alarm has been silenced. It
flashes when the alarm silence duration has been set to Off.
Lights whenever the N-600x algorithm detects the incoming
signal quality is degraded.
Note: Degradation can be caused by ambient light, electrical
noise, electro-surgical interference, patient movement, or other
causes.
An intermittently lit Interference Indicator is common during
patient monitoring, and indicates the N-600x algorithm is
dynamically adjusting the amount of data required for
measuring SpO and Pulse Rate. When lit continuously, the N-
2
600x algorithm has extended the amount of data required for
measuring SpO and Pulse Rate and consequently fidelity in
2
tracking rapid changes in these values may be reduced.
Lights continuously prior to initial acquisition of a pulse signal
and during prolonged and challenging monitoring conditions.
The pulse search indicator flashes during a loss-of-pulse signal.
