Please note that interval timer cannot used during the calibration. If you have set the interval timer
on, the watch will ask you to turn it off to enable manual stride sensor calibration. You can turn the
timer on from the pause mode quick menu after calibration.
Calibration factor: Set the calibration factor manually if you know the factor which gives you accurate distance.

PAIR A CYCLING SENSOR WITH YOUR WATCH
Before pairing a cadence sensor, speed sensor or a third-party power sensor, make sure they have been correctly
installed. For more information on installing the sensors see their user manuals.
If you are pairing a third-party power sensor, please make sure that you have the latest firmware both in
your watch and the sensor. If you have two power transmitters, you need to pair the transmitters one at a
time. After pairing the first transmitter, you can immediately pair the second one. Check the device ID on the
backside of each transmitter to make sure you find the correct transmitters from the list.
1. On your watch, go to General Settings > Pair and sync > Pair sensor or other device and press OK.
2. The watch starts searching for your sensor. Cadence sensor: Rotate the crank a few times to activate the sensor.
The flashing red light in the sensor indicates that the sensor is activated. Speed sensor: Rotate the wheel a few
times to activate the sensor. The flashing red light in the sensor indicates that the sensor is activated. Third-party
power sensor: Rotate the cranks to wake up the transmitters.
3. Once the sensor is found, the device ID is displayed. Press OK to start pairing.
4. Pairing completed is shown when you are done.
Bike settings
1. Sensor linked to: is displayed. Choose Bike 1, Bike 2 or Bike 3. Confirm with OK.
2. Set wheel size is displayed if you paired a speed sensor or a power sensor that measures speed. Set the size and
press OK. You can set the size from 100 mm to 3999 mm.
3. Crank length: Set the crank length in millimeters. The setting is visible only if you paired a power sensor.
Measuring wheel size
Wheel size settings are a prerequisite for correct cycling information. There are two ways of determining the wheel size of
your bike:
Method 1
Measure the wheel manually for the most accurate result.
l
Use the valve to mark the point where the wheel touches the ground. Draw a line on the ground to mark that
l
point. Move your bike forward on a flat surface for one complete rotation. The tire should be perpendicular to the
ground. Draw another line on the ground at the valve to mark a full rotation. Measure the distance between the
two lines.
Subtract 4 mm to account for your weight on the bike to get your wheel circumference.
l
Method 2
Look for the diameter in inches or in ETRTO printed on the wheel. Match it to the wheel size in millimeters in the right
column of the chart.
