Pulse Tone Volume
When SpO
2
is selected as the tone source, the pulse tone changes
with the level of arterial oxygen saturation. Low saturation levels
result in low pitched tones; high saturation levels result in high
pitched tones. If SpO
2
is selected as the tone source but is not cur-
rently being measured, no pulse tones are heard. You can adjust
the pulse tone volume or turn the pulse tone off. The available
settings are:
! High, Medium, Low and OFF.
STEPS: Selecting the Pulse Tone Volume
1. Click on the SpO2 parameter box.
2. Click on
Tone Volume.
3. Select the desired setting and click the knob.
NOTE: If you select a Tone Volume higher than the speaker vol-
ume of the monitor, the Tone Volume is that of the speaker volume.
If you select a lower setting, the pulse tone sounds at the selected
volume.
