2. Verify the following:
u Models 115, 145: The corresponding FHR display reads 0 BPM.
u Models 116, 118, 150, 151, 118, 155 and Series 120, 170: The
corresponding FHR display shows “– – –”.
If the display fails to illuminate, ensure that the corresponding
interconnection cable is firmly attached to both the monitor and the
receiver.
3. Use your finger to gently rub the ultrasound transducer face in a
rhythmic manner—to simulate a FHR. Try to maintain a steady rate
and verify the following on the monitor:
u the corresponding FHR display value responds to the rubbing;
u the corresponding FHR heartbeat indicator responds to the
input; and
u the ultrasound audio tones are synchronous with the transducer
stroking.
