Precautions
Communication Range
Do not separate the transmitter from the receiver or smart device by more
than 20 feet. The transmission range from the transmitter to receiver or smart
device is up to 20 feet without obstruction.
Types of obstruction differ and not all have been tested. Obstructions can
include water, walls, metal, etc. If your transmitter and display device(s) are
more than 20 feet from each other or are separated by an obstruction, they
might not communicate, resulting in you missing a severe low or high glucose
event.
As with any wireless device, water in reducing the communication distance.
This applies to the transmitter and display devices. Take special care when
swimming, taking a bath, or getting into a hot tub.
Setting Alarm/Alert Notifications
When using both a receiver and a smart device, you must set your settings
separately in each. If you set up one device and then use another, you might
not get an Alarm or Alerts, causing you to miss a severe low or high glucose
event.
Using an accessory device (like a smart watch) might override your smart
device sounds. Alarms or Alerts might vibrate or be heard on the accessory
instead of your smart device. After connecting any accessories, make sure
that the smart device settings allow you to continue receiving Alarms or Alerts
on the smart device.
Is It On?
If the receiver or smart device is turned off (Shut Down), it will not display
sensor data, information, Alarm or Alerts. Make sure they are turned on;
otherwise you won’t get sensor glucose readings or Alarm or Alerts, causing
you to miss a severe low or high glucose event.
