50 | Continuous Glucose Monitoring System

HELPFUL HINTS:

• Make sure a glucose reading is displayed at the top of the Trend Graph,

or a Blood Drop Symbol

is displayed in the top right corner of the Trend

Graph, before calibration.

• Only ﬁ ngerstick readings between 40-400 mg/dL can be used for

calibration. If 1 or more of your readings entered was outside of this range,

the Receiver will not calibrate. You will have to wait to until your blood

glucose is in this range to calibrate.

• Always make sure the Antenna Symbol

is displayed in the upper left

corner of the Trend Graph before you enter ﬁ ngerstick readings for

calibration.

• You should always use the same meter you routinely use to measure

your blood glucose to calibrate. Do not switch your meter in the middle of

Sensor session.

4.3 STARTUP CALIBRATION

One (1) hour after you start the Sensor session (see

Chapter 3, Section 3.7) the Receiver will tell you that

you need to calibrate. The Receiver will show the

Double Blood Drop Prompt. If your Alerts are set to

the factory default settings, the Receiver will also

vibrate and beep to tell you it is ready for calibration.

1. You can also set your Receiver to vibrate only (see

Chapter 8, Section 8.5).

2. When you see this screen, press any Receiver button to clear the display.

3. Take 2 ﬁ ngerstick readings with your meter and enter them into the Receiver

(see Section 4.2).

NOTE: Your ﬁ ngerstick readings must be between 40 mg/dL and 400

mg/dL for calibration. The Receiver cannot use ﬁ ngerstick readings outside

of this range for calibration.
