Gauge Function Instructions:
1. Short press the Mode button (less than 1 second) once to change the backlight color: backlight sequence is red (default), green, blue, white, yellow, yellow green, orange, purple.
2. Long press the Mode button (>4 seconds) to enter setting mode:
a. Short press the button (2 seconds).
b. Scroll to the desired parameter group for the gauge, release the button, wait 4 seconds without op for data to be saved automatically and exit setting mode to normal display mode.
c. Once in the tachometer speed ratio setting mode, holding the button will continuously increase the numerical value, release the button for the value to decrease continuously. Speed ratio adjustment range: 1‑300.0. Adjust to your desired speed ratio value, release the button > 4 seconds, the number is automatically saved. Between 1‑12.0 speed ratio, the step value is 0.1, between 12.0‑300.0 speed ratio, the step value is 0.5.

How to Use:
Installation Steps:
Step 1: Cut a 52‑53mm diameter hole in your central control or other pre‑installed location, ensuring there is at least 70mm of space behind the panel.
Step 2: Insert the gauge into the hole.
Step 3: Align the bracket screw holes with the screws on the back of the gauge, then tighten the screws to secure the bracket and frame to the panel.
Step 4: Plug the power harness directly into the back of the gauge's wiring port, then connect the corresponding sensor and harness according to the instructions provided to power on.
