Symbols, Controls, Displays and Indicators
N-600x Operator’s Manual 17
Low Battery
Indicator
Lights continuously when 15 or fewer minutes of battery capacity
remain. Flashes when the battery capacity reaches a critically low
condition.
Battery Fuel Gauge
Indicator
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.
Alarm Silence
Indicator
Lights continuously when an audible alarm has been silenced. It
flashes when the alarm silence duration has been set to Off.
Interference
Indicator
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
2
and Pulse Rate. When lit continuously, the N-600x algorithm
has extended the amount of data required for measuring SpO
2
and
Pulse Rate and consequently fidelity in tracking rapid changes in
these values may be reduced.
Pulse Search
Indicator
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.
