Model 171 Connectors

Figure 3-2. Model 171 Connectors

Ultrasound Connector

The ultrasound connector

1

is a blue, round receptacle mechanically keyed to accept

only a Corometrics ultrasound transducer plug. The fetal heart rate derived from
this transducer shows in the fetal heart rate display.

Uterine Activity Connector

The uterine activity connector is a white, round receptacle mechanically keyed to
accept a Corometrics tocotransducer. The uterine activity value obtained from this
transducer shows in the uterine activity display.

1

If the Model 171 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 transducer from the monitor, when not in use, to eliminate false alarms.
