About Vernier Shear Reduction
ƽ WARNING
The relationship between Vernier Shear Reduction (VSR) and the recline function
of the seating system is dependant on the needs of the user and MUST be set and
adjusted by a trained qualified technician.
Vernier Shear Reduction (VSR) moves the back of the seating system along with the
recline function. VSR reduces shear between the user and the seating system as the
seating system reclines.
NOTE: VSR is electronically linked to the recline function of the seating system and operating the
recline function automatically activates VSR.
VSR function can also be used independently from the recline function to allow for a
change in seating position or access to additional seating system options. Refer to Using
Vernier Shear Reduction (VSR) Independently of Recline Function on page 130.
Using Vernier Shear Reduction (VSR) Independently of Recline Function
ƽ WARNING
The back of the seating system MUST be returned to original position before the
degree of recline is changed (increased or decreased). Otherwise, the relationship
between VSR and the recline function of the seating system will change, possibly
resulting in injury to the user.
1. Make sure the wheelchair is on a level surface.
2. Note the current position of the back.
3. Push four-way toggle switch toward the left of the wheelchair until the desired VSR is
achieved.
NOTE: Left and right are determined by standing behind the wheelchair.
NOTE: The four-way toggle switch will alternate functions (move VSR actuator up, move VSR
actuator down) after it has been released to the neutral position for a minimum of one second.
NOTE: If the wheelchair is equipped with switch options, scan to the correct ECU or Auxiliary
Mode and activate the control device in the corresponding "left" direction to operate the tilt
function. Refer to MK
