HELPFUL HINTS:

• If you see

in the Status Area of the Trend Graph, it is recommended

that you wait out this period of time. Do not calibrate your System during

this time.

• When you see

, taking ﬁ ngerstick readings with your meter and

entering them does not help the System display more glucose readings.

Any ﬁ ngerstick readings that you enter during

will be ignored by the

System.

• Wait until you see a Single Blood Drop

in the Status Area before

entering a calibration value into your Receiver.

5.4.3 SYSTEM GLUCOSE ERRORS

Sometimes the G4-Global System may tell you that it

cannot provide a glucose reading. When this occurs

you will see 3 question marks (

) in the Status

Area.

Check the placement of your Sensor to make sure it

is still sticking securely to your skin. Also make sure

nothing is rubbing the Sensor Pod (i.e. clothing, seat

belts, etc.).

Check to see if the Transmitter is snapped in on both sides. This error can

happen when the G4-Global System detects problems with the glucose signal or

Sensor insertion area. Chapter 9 tells you how often you might expect to see this

error. Sometimes the G4-Global System can correct the problem and continue

providing glucose readings. However, if it has been 3 hours since your last

glucose reading appeared, contact Technical Support.
