Troubleshooting
Common problems that may occur when monitoring FHR using ultrasound are listed in “Monitoring
FHR and FMP Using Ultrasound” on page 155.
The following problem may occur when monitoring triplets.
For more information, see “Additional Information” on page 163.

Problem Possible Cause Solution
The question mark is
printed repeatedly, and
appears on the screen
and the INOP
Coincidence is issued.
More than one transducer is
recording the same FHR, or a fetal
transducer records the same heart
rate as the MHR.
Reposition one or more
ultrasound transducer, as
appropriate. See
“Recommended Actions
for INOP Coincidence” on
page 154
