SpO
2
Sensor Off L* B The SpO
2
sensor has become detached from the
patient or the module, or there is a fault with the SpO
2
sensor, or an unspecified SpO
2
sensor has been used.
Check the sensor application site and the sensor type,

Too Much Light L C
There is too much light on the SpO
2
sensor. Move the
sensor to a place with lower level of ambient light or
cover the sensor to minimize the ambient light.
SpO
2
Low Signal L C
The SpO
2
signal is too low or too weak. Check the
patient’s condition and change the sensor application
site. If the error persists, replace the sensor.

No Pulse L C
SpO
2
Interference L C
The SpO
2
signal has been interfered. Check for any
possible sources of signal noise around the sensor and

requirements and check if there is any source that
affects the air pressure.
NIBP Weak Signal L A
The patient’s pulse is weak or the cuff is loose. Check
the patient’s condition and change the cuff application
site. If the error persists, replace the cuff.
NIBP Signal Saturated L A
The NIBP signal is saturated due to excess motion or
other sources.
