CONTROL / INDICATOR DESCRIPTION
Patient Cable
Connector
Connects to Rainbow sensor or Rainbow Patient Cable
SpCO indicator
Slow flashing indicator: The confidence in the SpCO
value obtained is low.
Fast flashing indicator: Flashes when an SpCO alarm
condition exists.
Saturation
(%SpO
2
) and
Carboxyhemoglobin
(%SpCO) Displays
The functional arterial hemoglobin oxygen saturation
is displayed in units of SpO
2
. When searching for a
saturation and pulse, it will flash dashed lines.
See SpCO Button description, below.
%SpCO Bar
Illuminates when SpCO capable sensor is attached. Bar
will flash for SpCO alarm conditions.Continuously indicates
the concentration of carboxyhemoglobin in 5% increments.
Pulse Rate Display
The pulse rate in beats per minute (bpm). When searching
for a saturation and pulse, it will flash dashed lines.
system description
CONTROL / INDICATOR DESCRIPTION
SpCO Button
Pressing this button will display the numeric SpCO value
for 10 seconds in place of the SpO
2
numeric value.
Pressing the Mode/Enter or Next button during this 10-
second period will return to the SpO
2
numeric value.
Mode / Enter Button
Used to enter the setup menus and to select/activate
certain entries within the menu/setup system.
Next Button
Used within the menu/setup system to move through setup
options. Not active during normal patient monitoring.
Power On / Off

Battery Level Indicator
Four LED’s indicate the status of the battery. When the
final indicator begins flashing, replace the batteries.
Visual Alarm Indicator
Illuminates when any alarm condition exists. This indicator
may not be turned-off or otherwise over-ridden.
%SpO
2
/ %SpCO
Indicator
Indicator above label will illuminate to provide an additional
visual indication of the value currently being displayed.
PI
Perfusion Index, or PI, is a relative assessment of the
perfusion at the monitoring site. PI is displayed on a 10
segment LED bar, ranging from <1% (very weak perfusion)
to >5% (strong perfusion). The highest LED will remain
lit continuously to allow a PI level to be viewed. The
Perfusion Index is the ratio of the AC (pulsitile) to DC (non-
pulsatile) components of the IR (Infrared) signal where the
AC and DC components correspond to the pulsatile and
non-pulsatile amounts of blood, respectively.
Low SIQ
Flashes to indicate low SpO
2
Signal IQ. Refer to Section
4, Low Signal IQ.
Alarm Silenced
Indicator
Flashes to indicate the alarm is temporarily silenced.
Alarm Silence Button
Push once to temporarily silence the alarm for 120
seconds. Push a second time to return the unit to standard
alarm monitoring.
Up button
Down button
During saturation monitoring, use these buttons to adjust
the volume of the pulse beep tone.
Within the menu/setup system, these buttons are used to
select values within each menu option.
Speaker
Provides audible indication of alarm conditions, pulse tone
and feedback for key-presses. Ensure the speaker is not
covered or the unit is placed face-down on bedding or
other sound absorbing surface.
