The controller’s warranty will be voided if any device other than a PG Drives Technology
Programmer, or the battery charger supplied with the wheelchair, is connected into this socket.
4 Getting Ready to Drive
•
Operate the on/off switch. The battery gauge will blink then remain on after a second.
•
Check that the maximum speed control is set to a level which suits you.
•
Push the joystick to control the speed and direction of the wheelchair.
If you push the joystick before or just after you switch the controller on, the battery gauge will
ripple up and down and the wheelchair will not be allowed to move. You must release the joystick
to resume normal operation. If you do not release the joystick within five seconds the wheelchair
will not be able to move, even if you release the joystick and push it again. The battery gauge will
then flash rapidly. You can reset this condition by switching the controller off and on again.
If the battery gauge flashes rapidly, then the newVSI has detected a problem somewhere in the wheelchair’s electrical system.
Refer to section 8.5 for details.
5 Tips for Using Your controller
5.1 Driving - General
Make sure that the controller is mounted securely and that the joystick position is correct. The hand or limb you use to operate the
joystick should be supported, for example by the wheelchair arm pad. Do not use the joystick as the sole support for your hand or
limb - wheelchair movements and bumps could upset your control.
5.2 Driving Technique
The controller interprets your joystick movements and produces appropriate movements of your wheelchair. You will need very
little concentration to control the wheelchair, which is especially useful if you are inexperienced. One popular technique is to
simply point the joystick in the direction you want to go. The wheelchair will “home-in” on the direction you push the joystick.
The further you push the joystick away from the rest position, the faster the wheelchair will go. Releasing the joystick will stop the
wheelchair.
The intelligent speed controller minimizes the effects of slopes and different types of terrain.
The wheelchair user must be capable of driving a wheelchair safely. PGDT accepts no liability for losses of any kind arising from
failure to comply with this condition.
6 Precautions for Use
In the event of the wheelchair moving in an unexpected way RELEASE THE JOYSTICK. This action
will remove drive and power to the electro-magnetic brakes.
6.1 Hazards
Do not drive the wheelchair:
•
Beyond restrictions indicated in your wheelchair user manual, for example maximum inclines, curb height etc.
•
In places or on surfaces where a loss of wheel grip could be hazardous, for example on wet grassy slopes.
