Testing Ultrasound Transducers
If any of the following tests fail, repeat the test using another transducer. If the second transducer
passes the tests, confirming that the first transducer is defective, contact your service personnel.
If the second transducer also fails the tests, contact your Philips Service Engineer or Response Center.
To test an ultrasound transducer:
1 Switch on the monitor and the recorder.
2 Connect the transducer to the fetal monitor.
3 Select the fetal heart sound for this channel.
4 Increase the loudspeaker volume to an audible level.
5 Holding the transducer in one hand, move your other hand repeatedly towards and then away
from the surface.
6 Check that a noise is heard from the loudspeaker.
