4. Operating Instructions
The Control Unit provides advanced features to customize your racing experience. Refer to the specific buttons and indicators on the unit for detailed control.
4.1 Programming Functions:
- Braking Performance: Use the dedicated button (often labeled 'BRAKE') to adjust the braking intensity of individual cars. This allows for more realistic cornering and strategic driving.
- Power Adjustment: The 'SPEED' button typically allows you to set the maximum speed or power output for each car, catering to different skill levels or car types.
- Tank Capacity: The 'FUEL' button manages the virtual fuel tank capacity. This introduces a strategic element where cars need to pit for refueling, adding realism to longer races.
4.2 Special Race Functions:
- Pit Stop Functions: When tank capacity is enabled, cars will need to enter the pit lane (if available) for refueling. The Control Unit manages the pit stop duration and fuel levels.
- Pace Car Functions: Activate a Pace Car (if configured) to lead the field during caution periods or for practice laps. The Control Unit controls its speed and behavior.
