Precautions
• Keep transmitter close to display device:
Keep your transmitter and display device within
6 meters with no obstacles (like walls or metal)
between them. Otherwise, they might not
be able to communicate. If water is between
your transmitter and the display device – for
example, if you are showering or swimming –
keep them closer to each other. The range is
reduced because Bluetooth does not work as
well through water.
• Keep receiver clean and dry (receiver is an
optional display device): Do not submerge
your receiver in water and do not get dirt or
water in the USB port. That could damage it.
• Get alerts on display device you use
You will 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.
No glucose alerts unless you turn them on.
Turn alerts on during setup to get glucose and
system alerts when sensor warmup is over.
Dexcom ONE alerts will NOT override your
phone's settings. You will NOT hear high or
low glucose alerts if your phone is set to silent
(sound is off). Check your phone's settings, or
you may miss an alert.
• Is it on?
If the display device is turned off (shut down), it
will not show Dexcom ONE readings or alerts.
Make sure your display device is turned on.
• Check smartphone accessory devices
When using smartphone accessory devices
(such as headphones or Bluetooth speakers),
keep in mind you may get your alerts on
only one device or accessory, not all. After
connecting any smartphone accessory devices,
make sure that your smartphone settings allow
you to continue receiving alerts.
