2 Install or Replace Transmitter and Receiver Batteries
Purpose
To ensure that your FreeStyle Navigator system has power to operate properly.
Start
Do this procedure:
• The first time you use your FreeStyle Navigator system.
• When the receiver displays the Low Battery message and alarm and the battery
icon appears on the screen.
• When the receiver sounds an alarm and displays the “Replace TX Battery with
Next Sensor” message.
Materials
Gather these materials before you begin:
• 2 new AAA alkaline batteries for the receiver. We recommend Energizer® Max®,
Energizer® e2® Titanium®, and Energizer® Industrial batteries. Other batteries
may not provide expected battery life.
• 1 Silver Oxide 357 HC battery for the transmitter.
• A coin.
• Your FreeStyle Navigator Receiver.
• Your FreeStyle Navigator Transmitter.
Helpful Information
Caution: It is important to use the correct type of batteries in the receiver, otherwise the battery life
may not be accurately monitored.
Important:
An alarm will sound and a battery icon will appear on the screen when your receiver batteries are •
running low. You must replace your receiver batteries the next time you replace your sensor. Make
sure to replace batteries before inserting your next sensor.
An alarm will sound and a message will appear on the screen when your transmitter battery is •
running low. You have approximately 4 days of battery power remaining when this first happens.
Because you must insert a new sensor after each battery replacement, you should replace the •
batteries just before you insert a new sensor. For example, if you drop your receiver and the
batteries fall out, you will have to insert a new sensor.
After installing the transmitter or receiver batteries, allow a couple of minutes for the system to •
recognize new batteries. You may then access the status of the battery life from the System menu in
your receiver (see Status Information in Section 10). If the batteries are new, the status screen will
show 75-100% as remaining battery life.
• If your receiver batteries are low and you fail to replace them, they may run out without a
warning and the receiver will neither display your glucose levels nor sound alarms.
• The transmitter’s battery life is estimated to be up to 30 days.
• The receiver’s battery life is estimated to be 60 days. However, battery life may be shorter than 60 days
if your receiver’s alarms are set to vibrate, if you use backlighting frequently, or if the transmitter/
receiver connection is broken often.
• If you will not be using your receiver for an extended period of time, remove the batteries from the
receiver to preserve battery life.
• To avoid draining the receiver’s batteries, be careful not to accidentally press and hold the receiver’s
buttons for a long period of time.
• After changing the batteries, make sure that you reconnect the transmitter and receiver to establish
communication between them.
• If you are replacing batteries on both the transmitter and receiver, replace the battery in the
transmitter first.
