Problem
Lost communication
alert
Transmitter battery
empty alert
Mobile device battery
low alert
Change sensor alert
Sensor end of life alert
Calibration not accep‐
ted alert
Likely Cause(s)
The sensor pulled out
from the skin.
The transmitter battery
is empty and needs to be
recharged.
The mobile device bat‐
tery level is at 20% or
lower. The battery needs
to be recharged soon.
The current sensor does
not work properly and
needs to be replaced.
The current sensor has
reached the end of its life
and will no longer dis‐
play SG values on the
Guardian app.
The last calibration value
entered was not accep‐
ted by the Guardian sys‐
tem.
Resolution
Do not continue to use this sensor. Insert a new
sensor to continue to receive SG values. For
best results, recharge the transmitter before
starting use of a new sensor to ensure full trans‐
mitter battery life.
If the transmitter is still not communicating
with the app, contact the local Medtronic rep‐
resentative for assistance.
See the Guardian 4 Transmitter User Guide for
instructions on how to disconnect the trans‐
mitter from the sensor. For best results,
recharge the transmitter between each use to
ensure full transmitter battery life.
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.
Recharge the mobile device battery to ensure
that the Guardian 4 system can function and
send alerts. Remember to always carry a
charger for the mobile device to ensure con‐
tinuous use of the Guardian 4 system.
To continue to receive SG values, a new sensor
must be used. See the Guardian 4 Transmitter
User Guide for instructions on how to change
the sensor. For best results, recharge the trans‐
mitter between each use to ensure full trans‐
mitter battery life.
To continue to receive SG values, a new sensor
must be used. See the Guardian 4 Transmitter
User Guide for instructions on how to change
the sensor. For best results, recharge the trans‐
mitter between each use to ensure full trans‐
mitter battery life.
Wait at least 15 minutes before attempting
another calibration. The Guardian system will
request another calibration, if needed, after 15
minutes from when the Calibration not accep‐
ted alert was received. Review the BG meter
