OPERATION
After ANY adjustments, repair or service and before use, make sure that all
attaching hardware is tightened securely - otherwise injury or damage may result.
Set-up of the Electronics Control Unit is to be performed only by a qualified
technician. The final adjustments of the controller may affect other activities of the
wheelchair. Damage to the equipment could occur if improperly set-up or adjusted.

A Note About Drive Lock-Out

NEVER operate the wheelchair or elevate/lower the seat while the back is in any
tilt/recline/back angle position over 20° relative to the vertical position. If the drive
lock-out does not stop the wheelchair from operating or the seat from elevating/
lowering in a tilt/recline/back angle position over 20° relative to the vertical
position, DO NOT operate the wheelchair or elevate/lower the seat. DO NOT
attempt to adjust the drive lock-out. Have the wheelchair serviced by a qualified
technician.
The wheelchair user MUST have a clear line of sight to drive safely. On initial chair
delivery and after adjusting the back angle, drive lock-out switch, tilt system or
recline system, tilt and recline the seat back to the farthest driving position
IMMEDIATELY before drive lock-out engages and ensure there is a clear line of
sight present in which to drive the wheelchair. If a clear line of sight is not present,
have the back angle repositioned or readjust the lockout angle such that safe driving
with a clear line of sight is achieved. Otherwise injury or damage may occur.
One of the following will occur when the drive lock‐out feature has been activated:
• TILT WARNING displays on the joystick or display unit.
• SPM Inhibited displays on the joystick or display unit.
• SPJ+ joysticks Only ‐ Left to right chase alternating with a steady display.
Drive lock‐out is a feature designed to prevent the wheelchair from being driven after the
seating system has been tilted beyond 20°* relative to the vertical position. The back can
be positioned at a 10° relative offset to the seat base, thereby resulting in a back angle
potential of 30° before which the drive lock‐out is activated. This may affect the
wheelchair user's line of sight while driving. Make sure the wheelchair user can see
properly to ensure safe driving.
*NOTE: 20° back angle can be any combination of recline, tilt, back angle and/or surface angle.
NOTE: Refer to Typical Product Parameters for tilt and/or recline angle ranges.
