3. If pregnant woman adopts horizontal position and the fetus position is normal,
put the probe on the position of lower nave! midline to get the clearest FHR
sound.
4. Do not measure FHR unless audible fetal sound has been heard.
5. Please reduce the time of ultrasonic radiation as possible as you can.

4.2 Mode Selection

4.2.1 Real-time FHR Display Mode (Mode 1)
The moment when the fetal heart rate signals are detected, the fetal heart rate
bar graph on LCD indicates the strength of the fetal heart rate signals, and

4.2.2 Averaged FHR Display Mode (Mode 2)
This model is able to seguire more stable fetal heart rate, displaying on LCD
the latest acquisition of eight points fetal heart rate on average. When the fetal
heart rate is shown, the fetal heart rate bar graph on LCD indicates the strength
