Important: The smaller part of the sensor needs to face the crankarms and should not be 
attached to the top of the chainstay. You may have to tilt the main body of the sensor towards the 
wheel depending on your bike. You should make this adjustment after you have attached the 
spoke magnet. 
 
2. Attach the spoke magnet to one of the spokes on your bike. The magnet should face the chainstay 
where you attached the chainstay sensor. 
 
3. Adjust the position of the spoke magnet and the chainstay sensor so that when the wheel turns, 
the spoke magnet passes the tip of the main body of the chainstay sensor. 
Important: The distance between the chainstay sensor and the spoke magnet should not be 
more than 2 mm when they pass each other. On some bikes, you may have to tilt the main body 
of the sensor towards the wheel.

4. Attach the crankarm magnet to one of the crankarms on your bike. The magnet should face the 
chainstay where you attached the chainstay sensor. 
 
Tip: Make sure the different parts of the Cadence & Speed Sensor are lined up correctly on your 
bike. The spoke magnet should pass the main body of the chainstay sensor and the crankarm 
magnet should pass the tip of the sensor. 
 
Once you have adjusted the sensors to the right position, tighten the cable ties so they are held 
securely in place. 
5. On your watch, set the wheel size to help increase the accuracy of the metrics provided by the 
sensor. The wheel size is the circumference of your tyre in millimetres (mm). 
6. Move your bike or its crankarm so that at least one of the magnets passes the sensor. This 
switches on the sensor. 
7. From the Clock screen, press down. 
8. Select SENSORS, then press right. 
9. Select BIKE, then press right to turn it on. 
10. When you begin a workout, your watch connects to the sensor and you see an icon of a chainring 
at the bottom of the screen. 
 
When your watch is trying to connect to the Cadence & Speed Sensor, the chainring flashes. 
The first time your watch tries to connect to your sensor, if it finds more than one sensor, your 
watch doesnt know which sensor to connect to. Move to a place where there are no other sensors 
within range of your watch.  
						

							73 
 
 
 
When you have connected to your sensor once, your watch always reconnects to your sensor. 
When the chainring icon has stopped flashing, your watch is ready to measure your speed and 
cadence. You can start cycling with no GPS fix but for proper GPS tracking, wait until the GPS 
icon has also stopped flashing before you start your cycling activity. 
Tip: When you are using the Cadence & Speed Sensor for cycling activities, you are warned when 
no speed data is being received from the sensor. 
While you train, you can choose to show your current cadence or change the display to see your 
cadence. 
You can also use a training program to train to a target cadence zone. 
You can also use the Cadence & Speed Sensor with other Bluetooth® Smart Ready devices and 
apps. See the documentation that comes with your product or app for more information. 
To change the CR2032 battery on the sensor, use a coin to open the back of the sensor. The battery 
must be recycled or disposed of properly according to local laws and regulations.

 COMPASS - this is a built-in compass that needs calibrating before first use and on a regular 
basis thereafter to maintain accuracy. 
Tip: To help your watch last for up to 20% longer on a battery charge, turn off sensors that you are 
not using. Your watch keeps searching for sensors even if you are not using a sensor. 
You can check if a heart rate sensor is working without having to start an activity. See Testing a heart 
rate sensor.
