CHAPTER 26 • CGM Troubleshooting
This chapter provides helpful tips and
instructions to help you fix issues you
may have while using the CGM portion
of your System.
If the troubleshooting steps in this
chapter do not fix your issue, contact
Customer Technical Support.
The following tips are specific to
troubleshooting the Dexcom G6 CGM
connected to your pump. For more
information about Dexcom G6 CGM
troubleshooting, visit the
manufacturer's website for applicable
user guides.

26.1 CGM Pairing Troubleshooting

Possible issue:
Difficulty pairing your Dexcom G6 CGM
with your t:slim X2™ insulin pump.
Troubleshooting tip:
The Dexcom G6 CGM only allows
pairing with one medical device at a
time. Ensure your CGM is not
connected to the Dexcom receiver
before pairing with the pump. You may
still use a smartphone with the Dexcom
238
G6 CGM app and your t:slim X2 insulin
pump simultaneously with the same
transmitter ID. See Section 20.2
Disconnecting from the Dexcom
Receiver.

26.2 Calibration Troubleshooting

To ensure proper calibration of your
CGM, follow these important tips.
Before you take a BG value for
calibration, wash your hands, make
sure your BG test strips have been
stored properly and are not expired,
and make sure that your meter is
properly coded (if required). Carefully
apply the blood sample to the test strip
following the instructions that came
with your BG meter or test strips.
Do not calibrate if you see the Out of
Range symbol in the place where your
sensor glucose readings are normally
shown on the screen.
Do not calibrate if you see "- - -" in the
place where you sensor glucose
readings are normally shown on the
screen.
Do not calibrate if your BG value is
below 40 mg/dL or above 400 mg/dL.
26.3 Unknown Sensor Reading
Troubleshooting
When your CGM cannot provide a
sensor glucose reading "- - -" shows in
the place where your sensor glucose is
normally shown on the screen. This
means that the System does not
understand the sensor signal
temporarily.
Often the System can correct the
problem and continue providing sensor
glucose readings. If it has been at least
3 hours since your last sensor glucose
reading, contact Customer Technical
Support.
Do not enter any BG values for
calibration when you see "- - -" on your
screen. The System will not use a BG
value for calibration when this symbol is
on your screen.
If you see "- - -" often during a sensor
session, follow the troubleshooting tips
below before inserting another sensor.
