Accidents do occur. When working on or testing the wheelchair be aware of the dangers
and take care to ensure your own and other peoples health and safety.
Please note all regulations and rules about safety in electronics and mechanics.
4Adjustments
The majority of the adjustments can be carried out by the user or his family and are
covered in the instruction manual. However, the LEVO agent should always, on
delivery, adjust the wheelchair to suit the user.
The body-related settings of your LEVO combi are to be adapted precisely to
the needs of the patient. Improper settings can cause serious physical injury
to the user!

5Electronic control system
The preset settings are chosen to ensure safe operation. The settings are in compliance
with all relevant legal requirements regarding the entire operating range of the joystick
and the speed control. In case the preset settings don’t meet the needs of the user, the
control system can be programmed individually; the maximum speed might be
decreased for example.
Warning: Programming should only be conducted by healthcare professionals
with in-depth knowledge of Penny & Giles electronic control systems.
Incorrect programming could result in an unsafe set-up of a wheelchair for
the user. LEVO AG accepts no liability for losses of any kind if the drive or
stability characteristics of the wheelchair are altered without prior notification
and discussion with LEVO AG.
It is in the responsibility of the person programming the control system to make sure
that the stopping distance requirement specified for the country in which the
wheelchair will be used is satisfied. If the braking rate is low, the forward and reverse
maximum speed settings may need to be re-programmed. It is in the responsibility of
the person programming the control system to make sure that the settings are safe
and to note any programming changes made.
5.1 Programming R-Net and VR2
The programming is done by dubbing the control software of a laptop or PC to the
Controller of the wheelchair. Laptop / PC must be equipped with the appropriate PGDT
software.
• Start the software on your laptop / PC.
• Insert the read-in between the cable ends of the control panel cable and the
Controller; the interface is located below the armrest.
• Connect via the USB interface, the read-in on the laptop / PC.
• Transfer the program
The drive programs are made to give the user more ease of use and even better
drive characteristics.
All will be fitted with standard programs that provide the user with different
standard profiles programmed in the drive software.
The benefit for the user is that there is a more flexible way of speed and driving
settings in the chair, for both indoor and outdoor use.
Because multiple profiles per ordered speed setting are used, you do not need
to make the choice for the Standard, Classic and Fun at the order form
anymore.
