BUTTON OPERATIONS
RESET BUTTON
1. Press MODE button to the desired screen then press RESET button for
2 seconds to reset TRIP 2, MAX, and MAX RPM data from stored
values to zero individually.
2. The data of TRIP 1, AVG & RT can be reset at the same time when one
of the three data functions is being reset.
3. ODO, Clock and TT data cannot be reset.
MODE BUTTON
1. Press the MODE button to move all functions in loop sequence from one function screen to another when the speed sensor does not detect
any signal input.
SPEEDOMETER CALIBRATION
UNIT & WHEEL CIRCUMFERENCE SETTING
1. Setup operations include 12/24hour clock, shift RPM warning, numbers of engine rotations per signal, wheel circumference and units.
These must be set up step by step. The computer will automatic reversion to main screen if no button operation for 75 seconds at any
setting screen.
2. Press both MODE & RESET buttons to go into setting screen. In setting screens, press RESET button to add the flashing digit by 1,
press MODE button to confirm the digital setting and jump to next digit or next setting screen to be set. Press MODE button for 2
seconds at any setting screen to finish the setting and go to main screen.
3. It displays "12 or 24H and XX:XX-XX" symbols and AM/PM in case you select 12H.
4. Press RESET button converts 12/24H, press MODE button to complete the setting and jump to clock digit setting.
5. Press RESET button to increase flashing digit by one; press MODE button to confirm digit setting and jump to next digit.
6. Press MODE button to go to shift warning RPM setting screen after set clock.
7. It displays "rXXX00 RPM". Press RESET button to increase flashing digit by one; press MODE key to confirm digit setting and jump
to next digit.
8. Press MODE button to go to numbers of engine rotations per signal setting screen after completed shift warning RPM setting.
9. It displays "RPM SP 1r1P", the default value is 1r1P; there are 5 options: 1r1P, 1r2P, 1r3P, 1r4P, 2r1P, means the numbers of
enginerotation, “P” means number of signals from engine. For example the value 2r1P means the engine rotates 2 turns to output one
signal.
10. Press RESET button to move in loop sequence from one to another value of the 4 values. Press MODE button to confirm the setting
and go to wheel circumference setting screen.
11. In "cXXXX" display, "c" means "Circumference", following 4 default digits; flashing digit is digit to be set.
12. Press RESET button to increase flashing digit by one; press MODE button to confirm digit setting and jump to next digit.
13. Press MODE button to jump to unit setting screen.
14. It displays KM/h or M/h, each press of RESET button converts unit; press MODE button for 2 seconds to confirm unit setting and
jump to main screen.
15.It displays "SPD P-001", the pulses screen, the number of pulses into the computer per turn of the wheel. Follow item 2 of button
operation to finish the setting and jump to unit setting.
16. It displays KM/H or MPH, each press of RESET button converts unit; press MODE button to confirm unit setting and jump to
decimal point setting.
17.It displaysm "°C or °F" , each press of RESET button converts °C or °F ; press MODE button to confirm temperature setting and jump
to temperature warning setting.
18.It displays “ODO & 00000X km”, the “X” is from odometer testing in factory, follow item 2 to set a desired odometer value and jump
to clock setting or return to Normal Mode. This setting screen will disappear when the odometer is over 30km (18.6Miles) or your
setting is over 30km
SHIFT RPM WARNING OPERATION
1. Press MODE button to the RPM screen; pull on the throttle until the desired
shift RPM warning displayed.
2. Press RESET button to confirm and set up the shift warning RPM.
3. Bar-graphic tachometer will flash to warning you shift gear.
4. Operate items 1 & 2 to readjust the shift warning RPM.

2. Press the MODE button to move partial functions in loop from one function screen to another
when speed sensor detects signal input.

The speedo works by receiving electric pulses from the speed sensor. As the pulse rate increases the speed reading increases. To display an accurate speed reading the
distance travelled between each pulse needs to be entered in millimetres.
The first piece of information needed is the distance travelled per turn of the wheel.
Mathematically wheel circumference (in mm) = Tyre Diameter (in mm) x 3.1415 = Tire Diameter (inch) x 25.4(mm/inch) x 3.1416
To easily obtain the reading, mark the tyre and the ground where they touch. Push the wheel forward one revolution and mark where the ground again. Measure the
distance in mm - this is the rolling circumference, enter the distance into the "C" screen following the instructions below.
The second piece of information needed is the number of pulses per turn of the wheel - and this is entered into the "P" screen as below.
When using a magnet sensor system enter the number of magnets on the wheel - if you have 1 magnet then P=001, 4 magnets then P=004
If using a cable drive adaptor then enter the number of turns of the speedo cable per turn of the wheel, it will most likely be 2 or 3.
When using a factory speed sensor on the front hub, front sprocket or inside the gearbox then the number of teeth on the sensor need to be counted (and multiplied by the
drive ratio in some cases).
Always check your calibration against a GPS and ensure that the displayed speed is greater than the speed shown on GPS.
To increase a speed reading increase the number entered into the "C" screen.
