Quantum Dynamo ATS RevE/May03
VERSA SEAT ADJUSTMENTS
The Versa Seat is the standard seat assembly for your power chair.
After you have become familiar with your power chair’s operation, you
may find the need to make adjustments to the seat to increase your
comfort.
WARNING! If your Quantum Dynamo ATS was config-
ured at your authorized Pride provider or service cen-
ter, please consult your healthcare professional before
changing seat position or making any other adjustment.
Some of these adjustments may degrade your power
chair’s performance and safety by changing its center
of gravity.
SEAT HEIGHT AND ANGLE
You can change the seat height by either raising or lowering the four
seat posts attached to the seat base.
WARNING! Do not pick up the seat frame by the arm-
rests. They are free to pivot, and you may lose control
of the seat if they do so, resulting in personal injury
and/or damage to the chair.
To change the seat height:
1.
Remove the T-handle ball detent pins that secure the Versa Seat to
the power base.
2.
Raise or lower the seat posts attached to the seat base to the desired
height. You may find it easier to adjust the front posts first, and then
the rear posts. See figures 7 and 7a.
3.
Align the locating hole in the seat post with the one in the seat
mount connector, and reinsert the T-handle ball detent pin for each
post.

LIMITED ACTIVE-TRAC SYSTEM
Your power chair is equipped with a limited Active-Trac System (ATS).
See figure 6. ATS is a suspension system designed to make your power
chair traverse different types of terrain and obstacles while maintaining
smooth operation. With ATS, your front anti-tip wheels work in
conjunction with your motor suspension to help you maneuver over
obstacles.
As your front anti-tip wheels come in contact with an obstacle, the front
anti-tip wheel assembly is drawn upward. At the same time, your motors
are forced downward. This allows the motors to push your power chair
over an obstacle and limits the possibility of your power chair becoming
“hung up” on the obstacle.
ATS also helps in day-to-day operating conditions. For instance, when
you release the joystick, your power chair begins to slow down. As the
chair slows down, the front anti-tip wheels will automatically drop toward
the ground. This will reduce the forward tip that is typically encountered
with mid-wheel drive chairs.
