STARTING A SENSOR SESSIONStep 1: Inserting a New SensorThese instructions describe how to insert the Sensor into your abdomen, or belly. Please refer to the pictures and complete User’s Guide for further help. The Sensor must only be placed on your belly.

a. After you have cleaned your skin, then remove the adhesive backing from the Sensor Pod. Hold the Sensor by the plastic Applicator and try not to touch the sticky adhesive patch.

b. Place the Sensor on the area. You can place theSensorflatfacingtotheleftorrightofyour belly button. Make sure the Sensor is placed in the same direction shown in the picture to the right. You should not place the Sensor pointing in the up or down direction.

c.AfterplacingtheApplicator,pressfirmlyonandaroundtheoutsideoftheadhesivepatchtomakesureitisflat.

d. Hold on to the Applicator. Then pull the Safety Lock/Transmitter Key straight out away from the Applicator, in the direction the arrows show below.

The Safety Lock also serves as the “Transmitter Key.” Keep this piece to help you remove the Transmitter at the end of your Continuous Glucose Monitoring (CGM) session.

Hold down the Pod with one hand. With your other hand, place two fingersabove the collar on the barrel of the Applicator. Place your thumb on the plunger. Push the plunger down completely. This action inserts the needle and Sensor Probe under your skin. When you are pushing down on the plunger, do not pull back on the collar.

e. To remove the needle, keep holding the Sensor Pod with one hand. With your other hand,placetwofingersunder the collar. Then pull the collar back towards your thumb. Stop when you hear 2 “clicks” or cannot pull back any more. This step pulls the needle back into the Applicator and keeps the Sensor Probe under your skin.

f. Squeeze the ribbed release tabs on the sides of the Sensor Pod to remove the Applicator. When you squeeze the front release tabs, the back tabs will widen, allowing you to pull off the Applicator. After this step, only the Sensor Pod will be left on your body. Make sure the Transmitter Latch is down (against your body) to remove the Applicator.

h. The used Applicator can be thrown in the trash.

To start your CGM session, you must snap your Transmitter in the Sensor Pod and tell the Receiver of a new Sensor insertion.

2. Unknown Sensor Glucose Readings/??? In Status Box: Sometimes the SEVEN PLUS may tell you it cannot provide a glucose reading. Check the placement of your Sensor to make sure it is sticking well to your skin, and nothing is rubbing on the Sensor. The system will display “---“when it is recording glucose readings again.

3. Out of Range/Antenna in Status Box: When you see the Out of Range Symbol in the Status Box instead of a glucose reading, this means the Receiver has “missed” the last glucose reading sent by the Transmitter. Move the Receiver closer to make sure the Receiver and Transmitter are within 5 feet of each other.

If you have moved the Receiver closer and waited 5-10 minutes, the Out of Range Symbol in the Status box should go away. The Antenna Symbol should reappear in the lower right corner. If you are still having trouble, contact DexCom Technical Support at 1-888-SEVENGO (738-3646).

4. Sensor Error 0/“Err0” in Status Box: This screen means your Sensor cannot calibrate. Enter at least 1 more calibration fingerstickreadinginthenext10-15 minutes. If “Err0” remains in the Status Box afteryouenter2morefingersticksintotheReceiver, you may need to replace the Sensor.

5. Sensor Error 1/“Err1” in Status Box: This screen tells you that the Sensor is not calibrating correctly. If you see this screen, wait approximately one hour.
