Notice:Positive pole(+) should be set upwards. Then cover the the battery cover and screw down. Pedestal Installation In the accessories pack there has a strap which can be used to fasten the Seat onto the handlebar, as well we can use the back-up plate to fasten it. Sensor and MagnetInstallation Install the sensor onto the front fork of bicycle, and the magnet is installed onto the steel wire at the same side of wheel. Sensor can be underlaid with back-up plate and use the strap to fasten onto the front fork. It needs to be installed in 60cm distance from the computer, as the picture shows. Adjust the comparative location of Sensor and Magnet. The plane must face to the inductor. Keep the space to be 1.5mm. Magnet cannot be set to the center of Sensor face-to-face, it's better with the head or tail of Sensor Wheel Perimeter Setting Input the circumference from 0 mm to 999 mm. You can also measure it by yourself by the following ways: First make amark on the ground when the nozzle is on the below. Thenmake the wheels run once the gas mozzle on the below againplease mark. And measure the distance between the two marksyou can get your wheel perimeter. If the distance is 1615 thenyou should input 1615. (You can also measure the diameterand multiply 3.14 to get the perimeter.) Setting Steps 1 Put the battery on - Setting KM, M
