5 USAGE 5 Usage ƽ WARNING 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 Electronic 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 under these circumstances. 5.1 A Note About Drive Lock-Out ƽ WARNING NEVER operate the wheelchair while the back is in any reclined/back angle position over 20° relative to the vertical position. If the drive lock-out does not stop the wheelchair from operating in a recline/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 or drive lock-out switch, 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: 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 reclined 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. Invacare® Van Seat 20 Part No 1143195
