Introduction
Congratulations on buying one of the most exciting devices in the field of diabetes care! The Medtronic
MiniMed Guardian® RT (Real Time) System (M MT-7900) continuously monitors glucose levels, provides real-
time glucose values, and gives high and low glucose alerts. The Guardian RT uses three separate components—Sensor, Transmitter, and Monitor—to measure and display glucose levels in persons with diabetes.
The Sensor is inserted in the abdomen in fluid under the skin (Interstitial Fluid) and is attached to the
Transmitter. The Transmitter takes information from the Sensor and sends it to the Monitor. The Monitor is
a device that can store this information for real-time review, or can download it to a personal computer
using a Medtronic MiniMed Com-Station™ (MMT-7301) and the Guardian Solutions™ Software (MMT-7315).
This information is used by you and your doctor to identify glucose patterns and to improve your diabetes
management.
We know you are ready to start, but before you do, please read the following user guide to learn all
about the Guardian RT. Chapter 1 gives a general overview of the system. Chapter 2 offers step-by-step
instructions to get you started. Chapter 3 explains the routine operation of the Guardian RT. Chapter 4
walks you through the system alarms and troubleshooting approach. Chapter 5 goes over performance
characteristics, and Chapter 6 covers system maintenance and other important information.

System Function
The Guardian RT measures glucose levels in interstitial fluid: the fluid found between the body’s cells. It
is from this fluid that cells get oxygen and nutrients, including glucose. Glucose levels in interstitial fluid
typically match glucose levels in the blood. The system gives real-time interstitial fluid glucose values on
demand (updated every five minutes). The system also features low glucose and high glucose alerts that
are triggered once limits you have preset are reached. Data from the Sensor (which is placed under the
skin into the interstitial fluid) triggers the low blood glucose alert if your Sensor glucose value is less than
or equal to the preset limit. The high blood glucose alert is triggered if your Sensor glucose value is
greater than or equal to the preset limit. Glucose values are calculated and displayed based on the blood
glucose reference values entered periodically into the Monitor for calibration.
NOTE -
Before taking action based on glucose values or High and Low glucose alerts, check your blood
glucose using a home glucose meter available from your doctor or pharmacy.
System Components
Glucose Sensor
Figure 1.2
The Sensor (MMT-7002) is inserted through the skin into interstitial fluid. The Sensor
gives off a signal that is related to the amount of glucose in the interstitial fluid at the
insertion site. (See Figure 1.2.)
Transmitter
Figure 1.3
The Transmitter (MMT-7700) connects to the Sensor and is fixed to the skin with
medical tape. The Transmitter receives and processes signals from the Sensor,
and it sends the signals by radio frequency to the Monitor. (See Figure 1.3.)
Introduction 3
Monitor
The Transmitter sends Sensor data in the form of radio signals to the Monitor (MMT-7901) about every 5
minutes. The Monitor stores this information and uses it to provide real-time glucose values and to trigger
low or high glucose alerts. This information can also be downloaded for analysis to a personal computer by
means of a Medtronic MiniMed Com-Station™ (MMT-7301) and the Guardian Solutions™ Software (MMT-7315).
The system is calibrated by entering into the Monitor blood glucose values from a home glucose meter. Six
hours before a meter BG entry for the purpose of calibration is due, the word CAL will appear on the Monitor
screen. This icon will remain on the display until you enter a meter value. If you do not enter a meter value
within 12 hours of the last entry, an ENTER BG alarm is triggered. This alarm is also triggered if a calibration
has not been done in the last 8 hours since the first calibration. For best performance, enter a meter value
every 6 hours. A minimum of one meter value must be entered at least every 12 hours into the Guardian RT
for the real-time glucose display and the low and high glucose alerts to work.
Monitor Buttons
The Monitor is controlled by 5 buttons. (See Figure 1.4.) Always press the Monitor buttons slowly and
firmly.

User Safety
Indications for Use
The Guardian RT is indicated for continuous or periodic monitoring of glucose levels in the fluid under
the skin, in adults (ages 18 and older) with diabetes mellitus, for the purpose of improving diabetes
management. It alerts if a glucose level falls below, or rises above, preset values. Values are not
intended to be used directly for making therapy adjustments, but rather to provide an indication of when
a finger stick may be required. All therapy adjustments should be based on measurements obtained using
a home glucose monitor and not on Guardian RT values.
The Guardian RT provides real-time glucose values that allow users to track patterns in glucose
concentrations and to possibly identify episodes of low and high blood glucose. It also stores the data so
that it can be analyzed to track patterns. Glucose data can be further downloaded to PC software for
analysis of historical glucose values.
Contraindications
Use of the Guardian RT is not recommended for persons whose impaired vision or hearing does not allow
full recognition of the Guardian RT signals and alarms/alerts.
The Sen-serter is not indicated for use with product other than the Glucose Sensor. Medtronic MiniMed
cannot guarantee this product’s safety and/or efficacy if other sets are used.
