1. How to use the bicycle computer
The working principle of the bicycle computer is that the sensor captures the information brought by the induction magnet when the rim rotates, and the information is transmitted through the sensor wire. It is transmitted to the computer, and the host computer calculates the speed, mileage and other information after processing it.
Feature display
1. Automatically display. Press the function button (the big button below the stopwatch) until the word AUTO appears, then the stopwatch will automatically display the riding distance, time, total mileage and clock with an interval of 1 second.
2. Manual display. Press the function button, the word KM appears, indicating that the travel distance is displayed at this time;
Press the function button, an alarm clock pattern appears, indicating that the travel time is displayed at this time, and the display is accurate to the second;
p>
Press the function button, the word ?? appears, indicating that the accumulated riding distance since the computer is installed is displayed at this time.
3. The stopwatch is reset. Press and hold the function button for no less than 3 seconds, at this time the number on the stopwatch flashes, continue to press and hold until it is cleared, and clearing does not affect the accumulated riding distance.
Using Settings
This function determines the correct use of the computer and is very important. The main function is to input the circumference of the wheel, adjust the clock, change the speed unit, turn on the automatic display function, etc.
Enter the setting interface. Press and hold the setting button on the back of the stopwatch for 3 seconds, the word SET appears, and the setting interface is entered. At this time, the four-digit number displayed below is the circumference of the wheel. Press the function button at this time to enter the setting interface of the next function.
Exit the setting interface. Press the setting button for 3 seconds to return to the use state.
Second, how to install the bicycle computer
1. Install the base of the computer.
First install the base of the computer, there is foam glue on the back of the base, tear off the yellow glue and stick it on the handlebar, then use a rubber band to wrap around the handlebar, Snap into the slots on both sides of the base, and securely fix the base of the computer to the handlebar.
2. Next, install the sensor head.
The sensor cable is wound down around the brake cable until you need to install the sensor, which can be installed on the front bar halfway between the axle and the brake.
The installation method is similar to the installation base. After selecting the correct position of the sensor, press it with your fingers, and then use a large rubber band to wrap around the pole, and fasten the rubber band to the card of the sensor. in the slot.
3. Install the induction magnet.
The induction magnet should be installed on the steel strip of the tire and should be directly opposite the position of the sensor. After putting the soft magnet on the steel wire, use the iron ferrule in the installation package to clamp it in the groove of the magnet from bottom to top. Adjust the angle so that the magnet can face the sensor when the steel spoke passes through the sensor. , so the induction effect is the best.
After the stopwatch is installed, the next step is to adjust the wheel circumference of the stopwatch, so that the data read out is accurate.
4. Cycling computer set circumference parameters
How to set the wheel diameter of bicycle computer? Place the stopwatch on the base at a 45-degree angle, press down slightly, and turn it counterclockwise to fix it. Then find a straight line on the road, there are general cement grounds, people ride on the car, adjust the valve core of the tire to the nearest position on the ground, make a mark, keep riding in a straight line for 1 lap, and stop when the valve core is closest to the ground , the distance passed is the circumference of the wheel, so the measurement is more accurate than the reference value of the tire on the manual, because when a person rides on it, the tire pressure will change, do this 2 or 3 times, and take the average value is fine. For specific settings, you can adjust the stopwatch to the WHEEL SIZE menu and fill in the preset values.
Tips: The setting of the bicycle computer needs to be set according to the brand of the computer purchased and the model (such as: mountain bike, road bike, touring bike). Different brands of models have different stopwatch settings. Depending on the brand, the installation details are also different, and the model difference generally needs to be understood when debugging the computer data. Therefore, read the instructions carefully before installing the bicycle computer.
