• The symbol appears next to the measurement label, indicating that the measurement is being
made by a cordless transducer.
Preparing to Monitor
Prepare for ultrasound monitoring using the list below. The standard procedures in use in your facility
determine the sequence of actions.
•
Determine fetal position.
• Fasten the belt around the patient.
• Switch on the monitor and the recorder.
• Connect the transducer to a free socket. Note that the signal quality indicator for the heart rate
initially displays an invalid signal.
• Apply a thin layer of ultrasound gel to the underside of the transducer.
CAUTION
Using ultrasound gel not approved by Philips may reduce signal quality and may damage the
transducer. This type of damage is not covered by warranty.
• Place the transducer on the abdomen, if possible over the fetal back or below the level of the
umbilicus in a full-term pregnancy of cephalic presentation, or above the level of the umbilicus in
a full-term pregnancy of breech presentation. Work the transducer in a circular motion to ensure
the gel layer makes good contact.
When the sensor is connected correctly and a good signal is being received, the signal quality
indicator should be full. If an inadequate signal is being produced, the signal quality indicator will
indicate a poor signal, and no numeric will appear on the screen.
• Adjust the audio volume of the monitor's loudspeaker to a clearly audible level, while moving the
transducer over the abdomen. When you have a good signal, secure the transducer in position
below the belt.
