For the FM20 and FM30, you can connect an Avalon CL Cableless Fetal Transducer system interface
cable (red connector) to one of the fetal sensor sockets at the left side of the monitor.
For the FM40 and FM50, you can connect an Avalon CL or Avalon CTS Cableless Fetal Transducer
System interface cable (black connector) to one of the two dedicated black sockets marked "Tele" at
the rear of the monitor, as an alternative to using one of the fetal sensor sockets (red connector) at the
front.
What You See on the Monitor
When you connect a transducer or sensor, the measurement numeric appears on the screen.
Fetal heart rate measurements are labeled in the order in which you plug in the transducers for those
measurements. It does not matter which fetal sensor socket you use, as the monitor allocates a channel
automatically. For instance, when monitoring triplets, the first transducer you connect is automatically
allocated a channel, and the measurement is labeled FHR1, the second FHR2, and the third FHR3. See
also chapters “Monitoring Twin FHRs” on page 171 and “Monitoring Triple FHRs” on page 179.
When you touch a measurement numeric on the screen, the setup menu for that measurement opens.
The fetal sensor socket to which the transducer for this measurement is connected is identified by the
transducer position indicator in the blue setup menu header.
