Establishing an appropriate center of gravity for your
power chair is essential to promoting stability and safety
during its operation. At the time of initial manufacture,
the center of gravity of your power chair was factory
set to a position appropriate for the demographic
majority of users. At the time of delivery, a Quantum
Rehab authorized provider should perform a user-in-
chair evaluation and make appropriate adjustments to
the unit’s center of gravity, proper user position, weight
distribution and other features of your power chair to
promote stability and safe operation.These adjustments
are detailed in the Quantum Optimizing Guide provided
with your power chair. In addition, your Quantum Rehab
authorized provider will also evaluate your environment
to identify conditions that may affect the safe operation
of your power chair. Where appropriate, your Quantum
Rehab authorized provider may make further positioning
and/or programming adjustments to your power chair
to help address these conditions and help assure your
safety.
For your part, please alert your Quantum Rehab
authorized provider to any changes in your physical
condition or body mass. With the benefit of this
information, your Quantum Rehab authorized provider
can determine what if any adjustments should be made
to your power chair to help assure your safety.
In addition, should any fittings or fastening points on
your power chair or seating system become loose, or
your power malfunctions in any way, please alert your
Quantum Rehab authorized provider at once so that
appropriate repairs and/or adjustments can be made to
help assure your safety.
A lack of user-in-chair evaluation and adjustment of your
power chair, as outlined above, by a Quantum Rehab
authorized provider can result in unsafe conditions
including but not limited to user instability, tipping, falls,
contusions, abrasions, fractures, decubitus ulcers and
other forms of serious personal injury or death.
In the event of a loss of power to the power chair, transfer
to a safe position, seeking assistance if needed. Contact
your Quantum Rehab Provider immediately to report the
incident.
Your seating system is not approved for use as a seat
in any vehicle. Use the seats and occupant restraints
provided by the manufacturer of the vehicle.
