• Notifications (smartphone): Make sure
your smartphone settings allow Dexcom app
notifications to show on your lock screen.
This will allow you to see notifications
without unlocking your phone. During
Dexcom ONE setup, enable Dexcom app
notifications or you will not get alerts.
• Battery: Keep the battery of your display
device charged to avoid missing Dexcom
ONE data.
• Compatibility (smartphone): Before
upgrading your smartphone or its operating
system, check dexcom.com/compatibility.
Automatic updates of the app or your phone
operating system can change settings or
shut down the app. Always update manually
and verify correct device settings afterward.
• Time (smartphone): Let the date and time
on your smartphone automatically update
when you travel across time zones or switch
between standard and daylight-saving times.
Do not manually change your smartphone
time, because it can make the time on the
trend screen wrong and the app may stop
displaying data.
• Do not use receiver if damaged (receiver
is an optional display device): Do not use
a receiver that is damaged or cracked. A
damaged receiver could cause injuries from
electrical shocks and may make the Dexcom
ONE System not work correctly.
Follow Dexcom ONE instructions. If you do
not, you could have a severe low or high
glucose event.
Tips
• Use Dexcom ONE receiver: If you use the
Dexcom receiver, be sure to use the one
that comes with your Dexcom ONE system.
Receivers from previous generations won't work
with the Dexcom ONE system.
