- Adjustable Color: Users can select from 7 available backlight colors to match personal preference or vehicle interior lighting.
- Dual Warning System (Light and Buzzer): Two custom RPM warning thresholds can be set. When these RPMs are exceeded, the warning LED will blink or light up, accompanied by an audible buzzer.
- Exclusive Large-Sized Indicator: A dedicated large indicator light, illuminating in green or red, enhances warning visibility in addition to the main warning LED on the gauge.
- Peak Memory Function: The highest RPM achieved during driving can be recorded and reviewed later.
- Detachable Switch Unit: The large switch unit, which includes illumination, can be fixed directly to the gauge or detached for remote placement.
- Integrated Mounting System: The gauge is secured using an exclusive mounting band and back case, designed to neatly conceal wiring.

7. Troubleshooting
If you encounter issues with your Dyno Racing Tachometer, consider the following general troubleshooting steps:
- No Power/Display: Ensure all power connections are secure and correctly wired to a 12V DC source. Check for blown fuses in the vehicle's electrical system.
- Inaccurate RPM Readings/Jumping Needle: Verify that the RPM signal wire is correctly connected to the vehicle's ignition system or ECU. Ensure the gauge is set to the correct cylinder count for your engine (1-8 cylinders). Loose or incorrect wiring can cause erratic readings.
- Warning Light/Buzzer Not Functioning: Check the warning RPM settings to ensure they are configured correctly. Verify all connections related to the warning system.
- Illumination Issues: If the backlight is not functioning or stuck on one color, check power connections and consult the manual for reset procedures or color selection steps.
For persistent issues, it is recommended to consult a professional automotive electrician or contact Dyno Racing customer support.
