5.8 Functions of Controller
5.8.1 Power on and off
Power switch controls power to the controller and will switch the scooter on off. The screen lights up when the
controller is in on state and goes off when the controller is in off state.
The remote control key can also control power to the controller. Lock button can lock and turn off the controller.
Unlock button can unlock and turn on the controller.
It is recommended to turn off the controller when stationary for a long time to avoid consuming battery power.
5.8.2 Driving
NOTE: when power is turned on, the parking gear (P) is automatically selected to prevent the scooter
from accidentally moving until the user is prepared for their journey. To select drive mode (D), press
the red BRAKE button on the left handle controller.
With Power on and Drive gear selected (D), push the Accelerator lever to move the scooter forward. To go
backwards, press the reverse button on the right handle controller and then use the Accelerator lever. Releasing
the Accelerator lever will gradually bring the scooter to a stop. In P gear the Accelerator lever cannot be used to
move the scooter.
The speed up and down buttons are used to adjust the speed gear from 1 (slowest setting) to 5 (fastest
setting).
After pressing Neutral button for more than 1 second, the scooter enters freewheel mode. The electromagnetic
brakes unlock the motors, and the scooter can be move freely. Press the key for more than 1 second again or
press the red BRAKE button to exit the free move mode.
If the scooter is stationary for a long period of time, it will go into P gear again. The delay time before the scooter
goes into P gear is configurable.
The display shows the current PRDN gear and speed selected. D = Forward, R = Reverse, P = Park, and N =
Neutral (freewheel).
When the controller in the locked state, the scooter cannot switch to N gear.
5.8.3 Emergency brake
When an emergency brake is needed, press the emergency red BRAKE button. At this time, regardless of the
position of the acceleration knob, the scooter will slow down and stop at a faster rate.
5.8.4 Scooter platform lengthen and shorten function
To expand and contract the scooter’s wheelbase, use the Lengthen button and Shorten button on the display
panel. After pressing the corresponding button for 1 second, the scooter starts to expand or contract, and stops
immediately after releasing the button.
When the scooter speed is not 0, the expand and contract function cannot be used.
5.8.5 Battery level indicator
The three lights in the right handle button combination indicator the battery level. More lights illuminated = higher
battery capacity. Please charge the battery in time when the battery indicator is low.
5.8.6 Horn and headlight function
When the horn switch is pressed, the horn will sound and stop when it is released.

FreedomChair Scooter S1 Operating Manual
13
When the headlight switch is turned on, the headlight and the tail light are turned on at the same time. When the
headlight switch is turned off, the headlight and the tail light are turned off at the same time. The headlight indicator
on the panel indicates the headlight state. The backlight brightness of the panel decreases when the headlight is
turned on and increases when the headlight is turned off.
5.8.7 Turning light function
The left turning light flashes when the turning switch is turned to the left, the right turning light flashes when the
turning switch is turned to the right, and the corresponding indicator light on the rear light panel also flashes. When
the turning switch is set in the middle, neither of the turning lights is on.
When the turning light flashes, there is also an audible warning.
5.8.8 Brake light function
In the power on state, when the Accelerator lever is not pushed, the scooter is either parked or decelerating and
the brake light automatically illuminates.
5.8.9 Differential function
The controller measures the steering angle of the scooter and controls the difference in speed between of the left
and right motors according to this angle. This helps to prevent either of the drive wheels from scuffing during
turning, thus making turning smoother.
5.8.10 Turning speed function
When the scooter turns, the speed of the scooter decreases corresponding to the steering angle, thus reducing the
risk of rollover caused by high-speed turning of the scooter.
5.8.11 Power on self-test function
After the controller is power on, self-inspection of the control system will take place. If the self-inspection fails and
reports an error, the scooter cannot run. The self-inspection items include the communication function of controller,
Hall state of motor and electromagnetic brake. See the chapter on controller troubleshooting for specific fault types.
5.8.12 Brake function
The controller and the motor are matched with electronic braking and electromagnetic braking functions. In downhill
or other similar situations, the controller generates an electronic brake function through the motor to limit the speed
of the scooter, and also enables the scooter to stop quickly through the electronic brake function. In the parking
state, the electromagnetic brake locks the motors to enable the parking function. When the scooter is moving, the
electromagnetic brake unlocks the motors.
5.8.13 Energy recovery
When the electronic brake operates, the motor works in regeneration mode, charging the battery to recover energy.
5.8.14 Automatic power off
If the scooter is stationary for a long period of time, it will go into P (Parking) gear. The delay time before the
scooter goes into P gear is configurable. Config to zero disables the automatic power off function.

5.9 Controller Configuration
Characteristics of the scooter can be adjusted to satisfy different users' preferences by configuration of some of its
parameters.
** NOTE: changing the scooter’s parameters is done entirely at the risk of the user. The national
distributor or reseller of the scooter cannot be held responsible for any damage caused to the
scooter’s components or any injury to the user caused by changes that could affect the safe operation
of this transportation device. **
Before making any changes to a parameter, it is recommended to make a note of the parameter’s value so that it
can be restored to its original setting.
In the power off state, press the button and button at the same time, then press the power switch to
turn on the controller and enter the parameter configuration mode. Now release all buttons.
The and buttons select the configuration parameter. The and buttons are then used to change the
parameter’s value.
To exit configuration mode, press the power switch to turn off the power.
