LOW GLUCOSE ALERT

When your sensor glucose readings are at or below
your low alert level, this screen will appear with your
low glucose alert value displayed. Your receiver will
vibrate and/or beep depending on your profile setting.
When you set the low glucose alert, this level is
indicated by a red line on the trend graph.
The receiver will continue to alert you until you press
the SELECT button to clear the alert, or until your
sensor glucose readings rise above your low glucose
alert level. You can choose to have the receiver
re-alert you after clearing the alert, by changing
your snooze settings (see Chapter 6, Section 6.2,
Advanced Alerts).
HELPFUL HINTS:
• When you have both your high and low alerts turned on there will be a
gray zone on your trend graphs indicating your target range.
• If your high or low alert is turned off this gray zone will not appear.
