Damage due to radiation
If you are going to have an X-ray, MRI, diathermy treatment, CT scan, or be exposed to other types of
radiation, REMOVE YOUR MONITOR, TRANSMITTER, and SENSOR and leave them outside the radiation area.
The Guardian REAL-Time CGM System monitor and transmitter are designed and tested to tolerate
common electromagnetic interference, including microwave ovens.
The monitor is designed to withstand common electromagnetic interference, including airport security
systems. Medtronic has conducted official testing on the effects of the full body scanners at airports with
Medtronic medical devices. Important information about airport security systems, and using your monitor
on an airplane, can be found on the Emergency Card. Be sure to carry the Emergency Card provided, when
you are traveling.
Compliance information
CAUTION: Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
The monitor, meter, and transmitter comply with the United States Federal Communications Commission
(FCC) and international standards for Electromagnetic Compatibility. For the specific regulations and test
results for your area, please contact our 24 Hour HelpLine.
The transmitter should be disconnected from the sensor while traveling on an aircraft, or if it interferes
with another transmitting device. Do not use an RF-capable meter to send blood glucose measurements to
your monitor while traveling on an aircraft. Manually enter your blood glucose reading into your monitor.
These devices comply with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
1 These devices may not cause harmful interference
2 These devices must accept any interference received, including interference that may cause
undesirable operation.
These standards are designed to provide reasonable protection against excessive radio frequency
interference and prevent undesirable operation of the device from unwanted electromagnetic
interference.
