5) Since this instrument is a monitoring type instrument, which uses an advanced and unique algorithm,
the detected fetal heart rate signal, uterine contraction pressure signal and fetal movement signal will be
delayed for approximately 3 seconds before they are displayed. This has no adverse effect on the
clinical value of this instrument, on the contrary, this will be helpful for this instrument to capture each
fetal heart beat more
NOTE: When the Doppler Transducer is put not on the back but on the breast part of fetus, accurate
ultrasonic waves cannot be caught from the fetal heart and fetal heat beat can be frequently missed.
