Connect another, similar, known good module to the suspect patient monitor and check if
the module works normally:
− “Yes” => The suspect module is most likely faulty. Refer to Module Frames and
Modules Technical Manual for troubleshooting instructions.
−
“No” => The problem is most likely in the patient monitor. Continue troubleshooting
the problem according to the related troubleshooting chart below.

Problem Possible cause Recommended action
Recorder does not work. Graph location is not configured
correctly. Check the configuration: Monitor Setup >
Printing > Devices > Setup.
Recorder unit failure. Replace the recorder unit.
CPU board failure The serial communication for the recorder
is managed by the EMBC section of the
CPU carrier board.
- Check EMBC Frame logs for possible
EMBC failures.
If the cause is none of the above, the
problem is most likely in the CPU
assembly. Replace the CPU assembly.
Recorder works but nothing
appears on the paper. Paper installed upsidedown. Turn the paper roll over.
To test which side is active:
- Place the paper on a hard surface and
draw a line with a fingernail - a dark
line will appear on the active (thermal)
side.
