Pulse Rate display:
• shows the pulse rate in beats per minute
• flashes throughout loss-of-pulse alarms and when
the pulse rate is outside of the alarm limits
• shows two dashes throughout Sensor Disconnected
and Sensor Off Patient conditions
• shows pulse rates outside of the pulse rate range
(0, 20 to 300 bpm) as the closest value within the
range
• shows a decimal point (.) after the BPM value
(123.), if alarm limits have changed from their
power-on defaults
Low Battery indicator. Flashes when 15 or fewer
minutes of battery capacity remain. The indicator
displays constantly when the battery capacity reaches
critical condition at which time the monitor indicates an
error condition and shuts down.
Alarm Silenced indicator. Displays when audible alarms
have been silenced. It flashes when the audible alarms are
disabled.
Interference indicator. Lights when the N-65 algorithm
detects the incoming signal quality is degraded.
Degradations can be caused by ambient light, electrical
noise, electrosurgical interference, patient activity, or
other causes. An intermittently lit Interference indicator
is common during patient monitoring, and indicates that
the N-65 algorithm is dynamically adjusting the amount
of data required for measuring SpO
When lit continuously, it indicates the N-65 algorithm
has extended the amount of data required for measuring
SpO and Pulse Rate and, consequently, fidelity in

tracking rapid changes in these values may be reduced.
