The setting for the perimeter of Tyre and the comparison table of Tyre specification
Note: generally there is no need to set perimeter for the riding of adults, the default value of the system is 2124mm.
The perimeter of wheel: that is the distance of one cycle finished by the wheel towards the straight line, unit mm. Measuring method:
- Mark at the position of starting point for the wheel (the vertical point of the wheel that touches the ground), then push the vehicle towards the straight line until the mark reaches the other end of the straight line — the terminal. Then use the ruler to measure the length of the straight line and that is the perimeter of the Tyre.
- Directly measure the diameter of the Tyre, use the calculation formula: diameter of the Tyre x 3.1416.
- Input by the following table for the regular Tyre.
Press the right and left buttons at the same time (without releasingS/M) for a continuous 3 seconds (or reinstall the battery) and do not release until the display of the whole screen, 2124 enter the setting for perimeter, unit mm, press the numbers of the right buttons to add and minus for the setting before pressing the left button, follow this rule for the setting, for example, if the perimeter is 1.651m, then the input should be 1651. Continue to press the left button and it will display (kilo/080) to indicate the weight for the measurement of calorie, the unit is kilogram, press the left button to confirm for the entry to the next stage which is the setting for the maintenance of bicycle mileage and the screen will display the maintenance of bicycle. The 200 displayed in the middle is the system default of 200 km, similar to the setting for the perimeter, set your ideal mileage, after the setting, the stopwatch will enter the interface for the function of speed measurement.
Night lights turned on
Power saving mode of night lights:
Press the right button (S) with lights for 6 seconds.
Constant light mode of night lights:
Press both the right and left buttons (SIM) at the same time and that is the constant light
.
Setting of perimeter
In the speed mode, press the left and right button together for a continuous 3 seconds to enter the display of full screen, release your fingers and enter the selection of speed unit for KM and M(kM indicates kilometer/ Mindicates mile)
- Settings for speed unit
KM indicates kilometer, M indicates mile Right button for the selection of KM and M Left button for confirmation
- Weight (the setting for the parameters of calorie)
Body weight unit: kilogram Input your body weight parameters to calculate the consumption of calorie, press the numbers on the right buttons to add and minus, press the left button to confirm. Follow the same rule to set the value of parameters.
Maintenance setting and reminders’ function
Press the numbers on the right button to add and minus, press the left button to confirm, and follow this rule. When the mileage reaches the set value, the “bicycle maintenance” will flash for reminding, press the left button for 3 seconds in the interface for a single trip to turn off the flash, next time when the mileage of asingle trip reaches the preset mileage, the bicycle maintenance will again flash for the reminding ofmaintenance.
TEMP (temperature)
- Temperature unit: Celsius (C) and Fahrenheit (F)
- Unit setting: right button for selection and left button for confirmation
Setting for zero clearing
Clearing to zero is not possible in the loop cycling mode of the (SCAN) menu, in the mode of single trip and riding time, long press the left button for about 3 seconds and it will display “0.0” which indicates the successful clearance to zero. 
The function of contrast clues
When 
appears on the upper left corner of the screen during the ride, 
indicates the current riding speed exceeds the average speed,
indicates the average speed exceeds the current riding speed.
Total mileage / highest speed
Display range of total mileage: 0.001~9999 kilometers(miles), when the number exceeds the maximum counting range, it will automatically return to 0 for recounting. The screen displays the highest ridding speed within the counting time for a single trip. 
Mileage for a single trip / riding time
The screen displays the range of mileage for a single trip. 0.001 ~ 9999 kilometers (miles), when the number exceeds the maximum counting range, it will automatically return to 0 for recounting. From the start of the riding time for a single trip to the time of total mileage 
Average speed / Calorie
The screen displays the average value pf speed within the counting time for a single trip. Calorie is the energy consumption of the riding sports. 
Clock settings (24 hours/12 hours)
Press the left button under the environmental temperature and the clock mode for a continuous 3 seconds to enter the selection of 24/12 hours, press the right button to choose – press the left button to confirm before entering the clock, press the right button to set- press the left button to confirm to enter the setting for minutes – press the right button again to set and press the left button again to confirm.
Setting for the initial value of the total mileage
Under the mode of total mileage and highest speed, press the left button for a continuous 3 seconds to enter the setting for the total mileage. When the change of battery exceeds 10 seconds and the total mileage is cleared to zero, you may re-input in accordance with the mileage record before the change.
Environmental temperature / clock
Environmental temperature: the environmental temperature during the riding, the environmental temperature can only be reached after the riding for 30 minutes. Clock: Beijing Time
Power saving mode
When there is no input of sports signal within 300seconds, the display of the screen will enter the status of closure, the clock will be remained. When there is input for the signal of riding or when you press any button, you may return to the mode before the closure and memorize the respective items of values before the closure
Instructions for the use of buttons
Press the right button for the random selection of the function modes displayed in sequence: the total mileage, highest speed, mileage for a single trip, riding time, average speed, calorie, environmental temperature, clock.
The installation of battery
Use a coin of 1 yuan to open the door of battery, take a battery with the type of 2032 and put it in with the positive electrode (+) at the upper side and the negative electrode (-) at the lower side, cover with the battery door and screw tight. (as it is shown in the image)
Faults and other reasons
| Faults | Reasons for the Faults |
|---|---|
| Blurred display for the interface during the riding | Change with the 2032 button battery |
| The speed per hour remains to be 0 during the riding | The magnet is not aligned with the position of the round convex cap of the sensor |
| The riding speed value does not match with the actual value | The parameters are set incorrectly, for example, the diameter of the Tyre is not set, the sensor and the base are not tightened, press the wheel tight and push it to the correct position. |
| Black screen | Excessive exposure under the sunlight with outdoor environment temperature being over 50°C and above, you should put it in a place with shadows immediately and leave it for a while and the display will recover to normality. |
