User's Manual

The countdown symbol fills in over time to show that you are

getting closer to the first calibration time.

You will not get sensor glucose readings, alerts and alarm during the countdown.

If you see the out of range symbol at the top of the screen during

the 2-hour startup, review the

following troubleshooting tips:

• Make sure your receiver and transmitter are within 20 feet of each other without obstruction. Check in 10

minutes to see if the antenna symbol shows in the upper left corner of the receiver screen.

• If the receiver and transmitter are still not communicating, check the device information screen to make

sure the correct transmitter ID is entered into your receiver (see Chapter 5, Section 5.2, The Settings Menu).

• If the correct transmitter ID is in your receiver and the receiver and transmitter are still not communicating,

contact Dexcom Technical Support (see Chapter 15, User Assistance).

At the end of the 2-hour startup period the receiver lets you know it is time to calibrate your sensor. Chapter

7, Calibrating Your Dexcom G4 PLATINUM System, tells you how to calibrate your sensor.

6.9 TAPING THE SENSOR POD

The sensor pod should stay on your skin using its own adhesive. But, if the patch is peeling up, you can use

medical tape (such as Blenderm, Tegaderm, IV 3000, 3M tape) for extra support. If you use tape, only tape

over the white adhesive patch on all sides for even support. Do not tape over the transmitter or any of the

plastic parts of the sensor pod. Do not tape under the sensor pod or leave any substance on the skin where

you insert the sensor.

6.10 TEMPORARY RECEIVER SHUTDOWN

There may be times when you want to shut down your receiver temporarily. Shutdown stops all

communication between the transmitter and receiver and turns the receiver off. You will not receive sensor

glucose readings or

any

alerts or alarm while the receiver is shut down, but your current sensor session will

continue. Follow these steps to shut down your receiver:

1. From the Main Menu, scroll to highlight “Shutdown.” Press the

SELECT

button.
