COMFORT ADJUSTMENTS
After becoming familiar with your power chair’s operation, you may find the need to make some adjustments to
increase your comfort, such as seat height and angle, armrest angle, foot platform height and angle, and controller
position.
NOTE: If your power chair is equipped with a Synergy Seat or TRU-Balance Power Positioning System, refer
to the information provided in separate manuals. If your power chair is equipped with a medium-back, a high-
back, or a reclining seat, refer to the following information.
WARNING! The center of gravity of your power chair was factory set to a position that meets the
needs of the demographic majority of users. Your authorized Quantum Rehab Provider has
evaluated your power chair and made any necessary adjustments to suit your specific
requirements. Do not change your seating configuration without first contacting Pride Mobility
Products or your authorized Quantum Rehab Provider.
WARNING! Some power chair components are heavy. You may need assistance to lift or carry
them. Please refer to the specifications table for specific component weights before you
disassemble the power chair.
WARNING! Remove the occupant from the power chair before making any adjustments.
