Wireless Sensors
Your Edge bike computer can be paired and used with wireless sensors using ANT+ or Bluetooth technology
(Pairing Your Wireless Sensors, page45). After the devices are paired, you can customize the optional data
fields (Adding a Data Screen, page54). If your device was packaged with a sensor, they are already paired.
For information about specific Garmin sensor compatibility, purchasing, or to view the owner's manual, go to
buy.garmin.com for that sensor.
