2.0 Important Information about your TRx System 
iImportant: Do not ignore unanswered questions. You have the right to understand the product and all aspects of its operation. If necessary, please contact Motion Concepts for information regarding any questions or concerns expressed.
The most important link in the delivery chain is you, the end user. You must be satisfied with the product in terms of function, safety and aesthetics. No sale is complete until you have received thorough training in all aspects of the care and use of the system.
Motion Concepts Power Positioning Systems are designed to accommodate a wide range of user needs. Only the dealer and the health care professional can ensure that the system meets your individual requirements. It is the dealer’s responsibility to ensure that the wheelchair and the power positioning system are set up properly and safely for your specific needs.
STABILITY
By changing your seating position (tilting, reclining, or elevating), you are changing the stability charac- teristics of the wheelchair. It is very important that the system is set up so that it is stable in all seating positions. When evaluating stability, remember the following:
Most TRx systems can be mounted onto the powerbase in various forward and aft positions. Make cer- tain that the position selected provides you with maximum stability over the full range of seating positions.
Consider all personal gear and accessories (backpacks, vent systems, extra batteries, etc..) that will be carried on the wheelchair. For example, a loaded backpack, attached to the back of the seating system, can significantly reduce the rearward stability of your wheelchair.
Consider the backrest being used. For example, a recessed back can shift your center of gravity back and significantly reduce the rearward stability of the wheelchair. Conversely, a thick back cushion will shift you forward and reduce the wheelchairs forward stability.
If using a back other than Motion Concepts, check with manufacturer to ensure it is suitable for power positioning system applications.
Consider the seat cushion being used. A thick seat cushion will raise your center of gravity and reduce the wheelchairs stability in all directions.
All TRx systems are equipped with drive lockouts. Make sure this is set so as not to compromise your sta- bility while driving.
All
Ensure all medical conditions are considered when setting up your wheelchair. Involuntary muscle move- ment such as spasms may affect the stability of the wheelchair, especially when the seating system is in a tilted or reclined position.
When a system is fully tilted or reclined, the front wheels of the powerbase should never come off the ground. If this occurs, please contact the Motion Concepts Technical Service Department immediately to resolve the issue.
