Objective: To unlock the scooter's maximum speed for use in appropriate riding environments.

Steps:

1. Turn on the scooter by pressing the power button.
   
2. Hold down the left brake lever (make sure it is fully engaged).
   
3. While holding the brake, quickly press the power button four times.
   
4. The scooter will switch between speed-limited and unlimited modes.
   

Note: Be careful when driving without a speed limit. Make sure you are in a safe and legal environment to drive at high speeds.

Purpose: Customize speed and distance units according to your region or personal preference.

Steps:

1. Turn on the scooter.
   
2. Press the power button five times to enter settings mode.
   
3. Press the power button once to enter P01 (display unit setting).
   
4. Press the right button until the number in the lower right corner of the LED display starts flashing.
   
5. Press once to switch between:
   0000 = KM/H
   0001 = MPH
6. Wait until the number stops flashing — the setting will be saved automatically

Purpose: Maintain a constant speed without holding the accelerator, convenient for long-distance journeys.

Steps:

1. Turn on the scooter.
   
2. Press the power button five times to enter settings mode.
   
3. Press the power button repeatedly until you reach P05 (cruise control setting).
   
4. Press the right button until the number "00000" starts flashing.
   
5. Press once to change the value:
   
   0000 = OFF (regulator disabled)
   0001 = ON (regulator activated)
   
6. Wait until the number stops flashing. The mode will then be active.
   

Note: Cruise control is only activated after maintaining the same accelerator position for several seconds while driving.

Purpose: Choose whether the scooter can start from a standstill with the throttle alone (Zero Start) or requires a manual kick before accelerating (Non-Zero Start) for added safety.

Steps:

1. Turn on the scooter.
   
2. Press the power button five times to enter the settings menu.
   
3. Press the button until you reach P06 (start mode setting).
   
4. Press the right button until the lower right value flashes.
   
5. Press once to choose:
   00000 = Zero Start (the accelerator can start the scooter from a standstill)
   
   
   00001 = Non-Zero Start (a manual kick is required before the accelerator will take effect)
   
6. Wait until the screen stops flashing.
   

Safety Tip: If you are new to electric scooters, it is recommended to use Non-Zero Start for better control.

Purpose: To ensure accurate speed and mileage display by adjusting the digital settings to the actual wheel size of your scooter.

Steps:

1. Turn on the scooter, then press the power button five times to enter settings mode.
   
2. Press the power button until you reach P03 .
   
3. Note the actual size of your wheels indicated on the tire (e.g.: 80/65-6.5).
   
4. Press the right button until the value flashes, then adjust it to match the actual diameter of your wheels.
   
5. Wait until the value stops flashing to confirm the setting.
   

Note: Incorrect wheel diameter adjustment will result in inaccurate speed readings and incorrect battery range estimates.

Purpose: The magnet count (number of permanent magnets inside the motor) allows the controller to accurately measure wheel rotation and speed.

Steps:

1. Turn on the scooter.
   
2. Press the power button five times to access settings.
   
3. Press to scroll to P04 .
   
4. Press the right button until the number flashes, then confirm or adjust the value.
   

Note: For all Ruitoo electric scooters, the number of magnets is 40 .

Important: If you change the controller, you must match this value to the actual number of magnets in the motor, otherwise you may encounter problems such as:

1. Difficulty starting
   
2. Irregular fluctuations in speed
   
3. Engine overheating
   
4. Vibrations or jolts
