2
Too Much Light × × 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.
SpO2 Low Signal × ×
SpO2 Weak Signal × ×
SpO2 Weak Pulse × ×
SpO2 Low Perf × ×
The SpO2 signal is too low or too weak. Check
the patient’s condition and change the sensor
application site. If the error persists, replace the

SpO2 Interference × × The SpO2 signal has been interfered. Check for
any possible sources of signal noise from the
area around the sensor and check the patient for
great motion.
SpO2 Board Fault × × There is a problem with the SpO
