AVOID using the same spot repeatedly
for sensor insertion. Rotate your sensor
placement sites, and do not use the
same site for two sensor sessions in a
row. Using the same site might cause
scarring or skin irritation.
AVOID inserting the sensor in areas
that are likely to be bumped, pushed
or compressed, or areas of skin with
scarring, tattoos, or irritation as these
are not ideal sites to measure glucose.
Insertion in those areas might affect
accuracy and could result in you miss-
ing severe hypoglycemia (low blood
glucose) or hyperglycemia (high blood
glucose) events.
AVOID injecting insulin or placing an
infusion set within 3 inches of the
sensor. The insulin might affect sensor
accuracy and could result in you miss-
ing severe hypoglycemia (low blood
glucose) or hyperglycemia (high blood
glucose) events.
DO NOT use the sensor if its ster-
ile package has been damaged or
opened. Using an unsterile sensor
might cause infection.

Chapter 2 – Important Safety Information
To calibrate the CGM System, DO
enter the exact blood glucose value
that your blood glucose meter displays
within 5 minutes of a carefully per-
formed blood glucose measurement.
Do not enter sensor glucose readings
for calibration. Entering incorrect blood
glucose values, blood glucose values
obtained more than 5 minutes before
entry, or sensor glucose readings might
affect sensor accuracy and could result
in you missing severe hypoglycemia
(low blood glucose) or hyperglycemia
(high blood glucose) events.
DO NOT calibrate if your blood glucose
is changing at a significant rate, typical-
ly more than 2 mg/dL per minute. Do
not calibrate when your receiver screen
is showing the rising or falling single
arrow or double arrow, which indicates
that your blood glucose is rapidly rising
or falling. Calibrating during significant
rise or fall of blood glucose may affect
sensor accuracy and could result in
you missing severe hypoglycemia (low
blood glucose) or hyperglycemia (high
blood glucose) events.
The System accuracy may be affected
when your glucose is changing at a
significant rate (e.g., 2 to 3 mg/dL/min
or more than 3 mg/dL each minute),
such as during exercise or after a meal.
AVOID separating the transmitter
and pump by more than 20 feet. The
transmission range from the transmitter
to the pump is up to 20 feet without
obstruction. Wireless communication
does not work well through water so
the range is much less if you are in a
pool, bathtub, or on a water bed, etc.
Types of obstruction differ and have
not been tested. If your transmitter and
pump are farther than 20 feet apart or
are separated by an obstruction, they
might not communicate or the commu-
nication distance may be shorter and
result in you missing severe hypoglyce-
mia (low blood glucose) or hyperglyce-
mia (high blood glucose) events.
DO NOT use alternative blood glucose
site testing (blood from your palm or
forearm, etc.) for calibration. Alternative
site blood glucose values may be differ-
ent than those taken from a fingerstick
blood glucose value and may not
represent the timeliest blood glucose
value. Use a blood glucose value taken
only from a fingerstick for calibration.
