ABOUT VERNIER SHEAR REDUCTION (VSR)
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.
Have the relationship between Vernier Shear Reduction (VSR) and the
recline function of the seating system periodically inspected to maintain
proper setting for the user. Otherwise, injury to the user may result.
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 FUNC-
TION in this section of the manual.
USING VERNIER SHEAR REDUCTION (VSR)
INDEPENDENTLY OF RECLINE FUNCTION (FIGURE 1)
The back of the seating system MUST be returned to original position
BEFORE the degree of recline is changed (increased or decreased). Oth-
erwise, the relationship between Vernier Shear Reduction (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 is determined by sitting in 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 (1)
second.
