Start-Up and Use

For example, suppose the time represented by the right-hand edge

of the screen in Figure 10 is 14:54:05. Scrolling one time period

to the right (4 minutes) results in the cursor relocating to the

center of the screen at the time period 14:58:05, with 6 hours of

data on both sides of the cursor. If no data was available to the

right of the screen, an invalid tone would sound. If only 3 hours

of data was to the right of the screen, the cursor would relocate to

approximately 3/4 of the way to the right of the screen, at the time

period 14:58:05.

Note: The screen will return to the monitoring mode if an alarm

sounds, the Alarm Silence Button is pressed or a trend or

histogram has been displayed for 5 minutes with no

button presses.

View

Pressing the VIEW softkey allows you to select the %SpO2 or

pulse rate trend or both (DUAL). You can also select the
