8-12 Infinity Vista VF6
8 ECG AND HEART RATE
Pulse Tone Volume
When ECG is selected as the pulse tone source, the monitor emits a tone every time it
detects a QRS complex. You can adjust this tone volume between 10 and 100% (or
turn the pulse tone off).
STEPS: Setting the Pulse Tone Volume
1. Click on the HR parameter box.
2. Click on
Tone Volume.
3. Select the desired setting and click the knob.
NOTE:
z Tone volume settings are common to both ECG and SpO
2
source signals.
Whatever setting you select for ECG is valid for SpO
2
and vice-versa.
z The monitor’s Master Speaker Volume (see the chapter Monitor Setup)
determines the volume of all tones. If you select a pulse tone volume higher
than that of the speaker volume, the pulse tone volume sounds only at the level
of the speaker volume. If you select a lower setting for the pulse tone, the pulse
tone sounds at the volume selected.
