SECTION 11. PRECAUTIONS FOR CONTROLLER USE
The Dynamic and Penny & Giles controller has been designed with the user safety as
the prime consideration. They incorporate many, sophisticated self – test features which
search for potential problems. If the controller detects a problem either in its own
circuits, or in the wheelchairs electrical system, it may decide to halt the wheelchair
depending on the severity of the fault. The controllers are designed to maximise the user
safety under all normal conditions.
In spite of their sophistication, the controllers cannot take into account, circumstances,
which put the wheelchair or controller outside their specified operating conditions, and
so it is important that the user follows the following precautions.
1.
Do not drive the wheelchair:
• Beyond restrictions indicated in the user manual.
•
In places or on surfaces where a loss of wheel grip could be
hazardous, for example on wet grassy surfaces.
•
If the controller or other crucial components are known to require
repair.
In the event of the wheelchair moving in an unexpected manner release the joystick.
This action will stop the wheelchair under any circumstances.
2.
Although the controllers are 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 advised that a
restraining device be fitted.
3.
It is recommended that a restraining device be used when operating the Power
Chair.
WARNING: Penny & Giles and Dynamic Controls accept no liability for losses of
any kind arising from unexpected stopping of the wheelchair or improper
programming of the controller or improper use of the wheelchair or controller.
