this transducer shows in the primary fetal heart display.
FECG Connector
The FECG connector

If the Model 173 is interfaced to a clinical information system (CIS), be aware that the CIS may be
designed to alarm when there is no fetal heart rate signal. Therefore it is recommended that you
unplug the ultrasound and/or FECG transducers from the monitor, when not in use, to eliminate false
alarms.
