HOW TO OPERATE THE U-DRIVE

 

1.

 

Joystick. 

The primary function of the joystick 

is to control the speed and direction of the 
wheelchair. The further you push the joystick 
from the centre position the faster the 
wheelchair will move. When you release the 
joystick the brakes are automatically 
applied. 

2.

 

On / Off button. 

The on/off button applies 

power to the control system electronics, 
which in turn supply power to the 

wheelchair’s motors. Do not use the on/off 

button to stop the wheelchair unless there is 
an emergency. (If you do, you may shorten 
the life of the wheelchair drive components). 
The battery gauge shows you that the 
wheelchair is switched on. It also indicates 
the operating status of the wheelchair. 

 

 

3.

 

Increase Speed / Profile. Press this button to 
increase the maximum speed of the 
wheelchair.  

4.

 

Decrease Speed / Profile. Press this button 
to decrease the maximum speed of the 
wheelchair. 

 

5.

 

Speed / Profile Indicator. 

This shows the 

maximum speed of the wheelchair. The more 
LEDs are lit, the faster the maximum speed. 

The wheelchair can be configured to use 
drive profiles. However, this is not included 
by default. For more information about drive 
profiles, contact your dealer. If the speed 
indicator ripples, this means the wheelchair 
is locked.  

 

To unlock / lock the wheelchair: 

 

Switch the wheelchair on 

 

Hold down the on/off button for 1 second 
(lock only) 

 

Deflect the joystick forwards until the control 
system bleeps 

 

Deflect the joystick backwards until the 
control system bleeps 

 

Release the joystick. There will be a long 
bleep and the wheelchair will be unlocked / 
locked. 

 

6.

 

Horn. Press this button to sound the horn. 
The horn will stop when you release the 
button.  

7.

 

Battery Gauge. This shows the battery 
power level of the wheelchair. 

 

 

The more LEDs that are lit, the more power 
is left in the battery. 

The LEDs will be lit 

constantly when the wheelchair is operating 
normally.
