ally and automatically for your safety.
3.Joystick
The joystick controls the direction and speed of your vehicle, pointing the joystick away from
the neutral position,(center), will move the vehicle in the direction where the joystick is pointing.
The farther away(forward/backward) the joystick is from the neutral position, the faster the
vehicle will go. The farther away to the right/ left the joystick is pointing, the sharp the turn of
the vehicle will be. To operate the vehicle gently push the joystick in the direction you want to
go. Returning the joystick to its neutral position,(center), will reduce the speed and stop the
vehicle by automatically applying the electromagnetic brakes.
Notes:
→After pressing the controller ON/OFF switch, allow two seconds to elapse before engaging the
joystick. This is a safety feature to prevent sudden starts.
→Gentle operation of the joystick will result in smoother transitions in speed and direction,
while sharp operation of the joystick will result in drastic transitions in direction and
velocity.
→When the wheelchair is in operation, the surface of the charger will become slightly hot.
→In case of emergency, let go of the joystick and the chair will come to a stop.
B. Controller Display
The controller display is a multifunction visual display. It can provide four types of
information:1)ON/OFF status , 2)battery condition meter, 3) Horn , 4) acceleration and
deceleration buttons.
1. N/OFF Status
When the power is on, the controller's LED will be lit up. If the LED is not lit, the controller
is OFF.
2. Battery Condition Meter
The battery condition meter is composed of 10 segments (three of red, four of yellow, and
three of green). It enables you to monitor battery charge. The battery condition meter
indicates the approximate amount of battery charge left.
→Red, yellow and green LEDs indicate that the batteries are fully charge
→Red and yellow LEDs indicate that you should charge the batteries if possible.
→Red LEDs indicate that you should charge the batteries as soon
battery voltage may cause your power wheelchair to become inoperative.
Note:
When the batteries begin to approach a discharged state, the first red LED will begin to
flash slowly, reminding you that the batteries need to be charged immediately.
C. Free-Wheeling:
Because the motors are designed to engage the electromagnetic brakes when the vehicle is not in
use or when the power is OFF, they also have a manual feature that allows them to "free-wheel".
