Choosing Paper Speed
You can choose a paper speed of 1, 2, or 3 centimeters per minute (cm/min). The default setting is 3
cm/min.
The ACOG technical bulletin on FHR monitoring states that "accurate pattern recognition is difficult if not
impossible at 1 cm/min and that 1 cm/min is only recommended for more economic screening. When FHR
abnormalities arise, the faster paper speeds will enhance FHR pattern recognition".
Additionally, because a change in paper speed results in a change in the appearance of an FHR trace,
you are advised to ensure ALL monitors in your institution are set to the same speed.
To set the paper speed (in Configuration Mode):
1 Enter the Main Setup menu using the SmartKey .
2 Select Fetal Recorder.
3 In the Fetal Recorder menu, you can see the current speed setting. Select Recorder Speed (only
visible in monitoring mode).
4 Select the desired speed from the given choices: 1, 2 or 3 cm/min.
Tearing Off the Paper: FM20/FM30
CAUTION
NEVER pull on the paper to advance it, as this can cause misalignment of the paper. ALWAYS tear
off the paper along the perforation.
To tear off the trace paper after monitoring:
1 If the recorder is running (the "recorder on" status indicator is displayed), turn off the
recorder by selecting the fetal recorder Start/ Stop SmartKey or the Stop Recordng
SmartKey.
2 Select the Paper Advance SmartKey . This advances the paper automatically to the next
perforation.
3 When the paper stops advancing, tear off the trace paper along the perforation.
Tearing Off the Paper: FM40/FM50
CAUTION
NEVER pull on the paper to advance it, as this can cause misalignment of the paper.
The recorder's paper guide incorporates a tear-off edge, allowing you to tear off the trace paper cleanly
where you like (not necessarily at a fold). When not using the paper guide, ALWAYS tear off the paper
along the perforation.
