Usage Features

Installation: The manual provides detailed instructions for installing the LCD meter, main wiring harness, active speed sensor, sensor wire set, temperature sensor, speed sensor brackets (M8/S type and M10/S type), Allen keys, meter bracket, M5 washers, M5x16LxP0.8 Allen screws, rubber strip, handlebar clamp, M8x20LxP1.25 Allen screw, M8 washer, and M8xP1.25 nut. It emphasizes careful wiring to avoid short circuits and proper sensor placement for accurate readings. Optional accessories like L-type speed sensor brackets, oil temp sensor adapters, and water temp sensor adapters are also mentioned.
Wiring: The wiring diagram illustrates connections for positive and ground wires, fuel, neutral light, motor oil light, engine light, high beam, and turn signals. It highlights the importance of connecting the red and brown wires correctly to ensure proper meter function.
Speed Sensor Installation: Detailed instructions are provided for both S-type and L-type speed sensor brackets, including how to position the sensor to face the magnet and adjust the distance (under 1 mm) for optimal speed signal. The manual also explains how the active speed sensor detects speed from metal surfaces like disc screws, disc gaps, and sprockets, recommending disc screws for better accuracy.
Setting Screen Navigation: The meter uses a single button for navigation and setting adjustments. Pressing the button for 3 seconds from the main screen (ODO) enters the setting screen. Subsequent short presses cycle through various settings: Clock, Unit (Speed/Temperature), Backlight (Color/Brightness), Tire circumference/Sensing point, Speeding warning, Temperature, Voltage, Fuel resistance/Low Fuel warning, Warning light warning, and Internal/External ODO.
Clock Setting: Users can set the time format (12H/24H), hour, and minute.
Unit Setting: Allows selection of speed units (km/h or MPH) and temperature units (°C or °F).
Backlight Setting: Users can choose from multiple backlight colors (white, red, orange, yellow, green, blue, light blue, purple) and adjust brightness (1/3 to 3/3).
Tire Circumference and Sensing Point Setting: This crucial setting involves measuring tire circumference and setting the number of sensing points (1-20 P) for accurate speed readings.
Speeding Warning Setting: Users can set a speed threshold (30-160 km/h or 19-100 MPH) that triggers a warning light when exceeded.
Temperature Setting: Enables setting the temperature function ON/OFF and configuring an overheat warning threshold (60-250 °C or 140-482 °F).
Voltage Setting: Allows setting the voltage function ON/OFF and configuring a low voltage warning threshold (DC 8.0-13.0 V).
Fuel Gauge Resistance Setting: This feature supports both auto-detection and manual setting of fuel gauge resistance values (100 Ω, 250 Ω, 270 Ω, 390 Ω, 510 Ω, 1200 Ω, SW, Custom, OFF) to match the vehicle's fuel sensor. It also includes a low fuel warning threshold (0-30%).
Internal and External ODO Setting: Users can view and set external total distance, with the internal ODO being non-adjustable.

Maintenance Features

Troubleshooting Guide: The manual includes a troubleshooting section to help users diagnose common issues such as the meter not working, displaying wrong information, incorrect speed readings, thermometer malfunctions, fuel meter errors, incorrect clock, and indicator display problems. It suggests checking wiring connections, battery voltage, sensor connections, and setting configurations.
Professional Repair: The manual explicitly states that maintenance and repairs should be executed by professionals only, and disassembling the unit will void the warranty.
Contact for Assistance: If problems persist, users are advised to contact the technical department for assistance.
