Likely Cause(s)
Another app is in use,
such as a game, that
takes up a lot of the
memory on the mobile
device. This means that
the Guardian app stops
running and can't com‐
municate with the trans‐
mitter.
The app has been
closed. The Guardian

or selecting Force Stop
for Guardian from an
Android™* device Set‐

Resolution
Open the app to ensure it is running properly.
Check periodically to see if the app is still run‐
ning in the background in order to receive
alerts and SG values.
Make sure the mobile device and the transmit‐
ter are located within 6 meters (20 feet). It is
helpful to keep the devices on the same side of
the body to minimize any radio frequency (RF)
interference.
Move away from any equipment that can cause
RF interference, such as cordless phones or
routers.
Reconnect the sensor to the transmitter. Be
careful not to pull the sensor out.
Note: When the transmitter is reconnected to
the sensor, the sensor will go through a
warm-up period which may last up to 2 hours.
