The basics
CAUTION: Never use sharp objects to press the buttons on your monitor as this can damage the
buttons or compromise the seal on the monitor. Some examples of sharp objects that can damage the
buttons or the seal are fingernail files, pens, pencils, paper clips, knives, scissors, and keys.
The monitor
The screen shows information such as your real-time sensor glucose
measurements, alarm/alert messages, current settings, and status readings.
The buttons are used to select menu items, enter values, and perform actions.
Installing the battery
CAUTION: Do not use a rechargeable or carbon zinc battery in your monitor. For best results, a new
AAA Energizer alkaline battery is recommended.
Medtronic has designed an important safety measure into the monitor: It measures battery strength during
installation. If you install a new, full-strength battery, the monitor accepts it. However, if you install a
battery that does not have full power, or take too long to switch batteries, the monitor will show one of
the following alarms:
WEAK BATTERY — The battery is weak but usable. Follow the instructions on the screen to clear the
alarm, then either install the weak battery, or install another new battery. Your monitor will work
with the weak battery, but the battery life will be reduced.
FAILED BATT TEST — The battery is not strong enough to power your monitor; your monitor will not
work with that battery. Clear the alarm and install a new battery.
BATT OUT LIMIT — May occur if the battery is removed from the monitor, and more than 10 minutes
passes before the new battery is inserted. If this alarm occurs, continue installing the new battery.
