Precautions For Use
The VR2-L control system has been designed with the user's safety as the prime
consideration. It incorporates many sophisticated self-test features which search for
potential problems at a rate of 100 times per second. If the control system detects a
problem either in its own circuits, or in the wheelchair's electrical system, it may decide
to halt the wheelchair depending on the severity of the problem. The VR2-L is designed
to maximize the user's safety under all normal conditions.
In spite of its sophistication, the VR2-L cannot take into account circumstances which
put the wheelchair or the controller outside of their specified operating conditions, and
so it is important that the user follows the precautions below:
1) Do not drive the wheelchair:
a) beyond restrictions indicated in the wheelchair user manual, for example
maximum inclines, curb height etc.
b) in places or on surfaces where a loss of wheel grip could be hazardous, for
example on wet grassy slopes.
c) if the controller or other crucial components are known to require repair.
In the event of the wheelchair moving in an unexpected way RELEASE THE JOYSTICK and
switch the on/off switch to off. This action will remove drive and power to the electro-
magnetic brakes
2) Although the VR2-L control system is designed and manufactured to be extremely
reliable and each unit rigorously tested, possibility of a system malfunction always exists
(however small the probability). Under some conditions of detected system malfunction,
the controller must (for safety reasons) stop the chair instantaneously. If the physical
impairments of the user are such that a sudden braking action could result in a fall from
the chair, it is imperative that a restraining device such as a seat belt be purchased
and installed with the chair. Restraining devices should be used at all times when the
wheelchair is in motion.
PGDT accepts no liability for losses of any kind arising from
unexpected stopping
programming of the control system, improper use of the
wheelchair, improper use of the control system or if any of
the criteria detailed in this document are not met. This sheet
should be read in conjunction with the VR2 Technical Manual
SK77898.
