2
Performance
The followings are symptoms of problems and recommended actions relating to SpO
2
operational performance. If the action requires replacement of a PCB or module, refer to
Disassembly Guide
.
1. No displays (blank) on SpO
2
display.
1-1. Replace SpO
2
module.
1-2. If problem persists, replace Main BD.
2. Dashes ‘- -‘ are displaying on SpO
2
display, but no data measured.
2-1. Verify that red LED of SpO
2
sensor is on. If not, replace the SpO
2
sensor.
2-2. Ensure that the LED intensity increases when opening the SpO
2
sensor.
2-3. If problem persists, replace SpO
2
module.
3. Error code, E49 displays.
