Dexcom ONE+ User Manual page 10

Where to store: You can store your sensors at room temperature or in your refrigerator, between 2°C and 30°C, but not in the
freezer.
Inspect: Don't use any damaged or cracked Dexcom ONE+ component because it may not work correctly and could cause
injuries from electrical shocks.
Use as directed: Dexcom ONE+ is small and may pose a choking hazard if swallowed. Don't put it in your mouth or let
children hold it without adult supervision.
Optional alerts: You won't get glucose alerts unless you turn them on. You'll be prompted to turn on the optional alerts when
setting up your Dexcom ONE+ system. You must turn them on to get glucose and System Alerts. Follow the instructions and
safety warnings in this user guide to make sure you receive alerts on your display device.
Dexcom ONE+ alerts won't override your display device settings. You won't hear high or low glucose alerts if your display
device is set to silent (sound is off). Check your display device settings, or you may miss an alert.
Check settings
Phone volume and sound: Make sure your phone volume is turned up, not muted, and the speaker works. If your phone is on
mute, "Total Silence," or "Do Not Disturb" mode, you won't get Dexcom ONE+ alerts. When headphones are connected to your
phone, alerts will sound through the headphones only, not on your phone speaker.
®
Bluetooth wireless technology: Make sure your Bluetooth is on. If not, you won't get readings or alerts.
Notifications:
Make sure your phone settings follow Dexcom's recommended settings. Certain phone settings such as Android's Digital
l
Wellbeing and Apple's Screen Time may prevent notifications if turned on.
Allow Dexcom ONE+ app notifications to show on your Lock screen. This ensures you receive Dexcom notifications and
l
allows you to see your notifications without unlocking your phone.
Android users must allow Location Permission, Do Not Disturb Access, and Notifications to use the app.
l
Apple users must allow Location Permission and Critical Alerts to use the app.
l
Battery: Keep the battery charged.
Compatibility: Before upgrading your phone or its operating system, check dexcom.com/compatibility. Automatic updates
to the app or phone operating system can change settings or shut down the app. Always update manually and verify correct
device settings afterward.
While connected to the internet, the app checks periodically and will display a message if it's not compatible (or no longer
compatible) with your phone or your phone's operating system (OS). The message may include a timeframe for updates.
Time: Let the date and time on your smart device automatically update when you travel across time zones or switch between
standard and daylight saving times. Don't manually change your smart device time because you may not get readings or
alerts, and it may make the time on the trend screen wrong.
