7 Freezing Waveforms
7.1 Overview
You can freeze the monitored waveforms of a patient as desired and view the waveforms of 40
seconds to gain a clear observation. Besides, the monitor can print three frozen waveforms using
the recorder.
The freezing function of the monitor has the following features.
When the monitor enters the frozen mode, it exits all other menus automatically.
The system freezes all waveforms displayed in the waveforms area.
The frozen waveforms can be reviewed and recorded.

3. All displayed waveforms are frozen. In other words, the waveforms stop being refreshed or
scrolling.
Exiting the Frozen Mode
To exit the frozen mode,
Select EXIT in the FROZEN menu, or
Press the FREEZE key on the control panel again.
After exiting the frozen mode, all waveforms on the screen are cleared and new real-time
waveforms are displayed. If the scan type of the monitor is set to REFRESH, the waveforms are
refreshed from the left of the waveforms area to the right ; if the scan type is set to SCROLL, the
waveforms are displayed from the right of the waveforms area to the left and are scrolling.
