5 USAGE 5.2 A Note About Drive Lock-Out ƽ WARNING NEVER operate the wheelchair while the back is in any tilted/back angle position over 20° relative to the vertical position. If the drive lock-out does not stop the wheelchair from operating in a tilt/back angle position over 20° relative to the vertical position, DO NOT operate the wheelchair. 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 or tilt system, tilt the seat back to the farthest driving position immediately before drive lockout 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: ƽ ƽ • CMPJ+ Joysticks Only - TILT WARNING or SPM Controller 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.  *20° back angle can be any combination of tilt, back angle and/or surface angle. Refer to Typical Product Parameters on page 26 for tilt angle ranges. Invacare® Adjustable ASBA Seats 30 Part No 1143192
