Ignore symptoms of high and low glucose.

your BG with a fingerstick.
Why: Your sensor glucose readings may not be accurately reading your
glucose.
Consequences: You may miss a severe low (hypoglycemia) or high
(hyperglycemia) glucose event.
Precaution
Do: When using both a receiver and a smart device, you must set your
settings separately in each.
Why: If you set up one device and then use another device with different
settings, you might not get an Alarm or Alerts.
Consequences: You may miss a severe low or high glucose event.
Precaution
Do: After connecting any accessories, make sure that the smart device
settings allow you to continue receiving Alarm or Alerts on the smart device.
Why: Using an accessory device (like a smart watch) might override your
smart device sounds.
Consequences: Alarm or Alerts might vibrate or be heard on the accessory
instead of your smart device causing you to miss severe low or high glucose
event.
