CHANGING THE BATTERY
The AA battery in the sensor must be replaced with a
new, unused battery every 24 hours. We recommend you
turn your monitor off before changing your sensor
battery. This prevents the monitor from signaling an
alarm because it cannot detect your heartbeats.
Replace the Battery
1.
Pull open the battery door.
2. Remove the old battery and dispose of it in
accordance with local regulations and EPA guidelines.
3. Put in a new AA battery, included in your CardioNet
Service Kit. Insert the positive end as shown. The
sensor chimes when the battery is correctly placed.
4. Close the cover.
If you are getting low on replacement batteries, contact
the CardioNet Patient Service Center and ask for
additional batteries. In an emergency, any available
AA battery can be used with the CardioNet sensor.
Pull the top edge of the battery
door to open it.
Insert the positive end as shown.
The sensor chimes when the
battery clicks in correctly. If there’s
no chime, you probably have the
battery backwards.
