Description
Lights continuously when 15 or fewer minutes of battery capacity
remain. Flashes when the battery capacity reaches a critically low
condition.
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 activity, 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-600x algorithm
2
has extended the amount of data required for measuring SpO
Pulse Rate and consequently fidelity in 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.
