Polar S725X user manual You only need to install one of them, How to put the transmitter on

4 4. There are two spoke magnet options.

You only need to install one of them.

		Check which of the magnets fits the spoke
		of your bike best. One (A) is installed by
		rotating it around the spoke before putting
		the metal cover on, another (B) by
		tightening the screw. The magnet must be
		facing the speed sensor.
		5. Fine-tune the positioning of both the
A or	B	magnet and the sensor so that the magnet
		passes the sensor closely but does not
		touch it. The maximum distance between
		the speed sensor and the spoke magnet
5		should be 5 mm/ 0.2". Once positioned
		correctly, tighten the cable ties securely
		and cut off any excess cable tie ends.
		Your safety is important to us. While riding
		your bike, please keep your eyes on the
		road to prevent possible accidents and
		injury. Check that you can turn the handle
		bar normally and cable wires for brakes or
		gearing do not catch on the sensor. Check
		also that the sensor does not disturb
		pedaling or the use of brakes or gearing.

1 meter/ 3 feet of your transmitter.
