7. Slowly move the drive lockout clamp in the following manner until the programmer
changes from FALSE (OPEN) to TRUE (TRECM or TAC) or the drive lockout light
illuminates (TRSS):
• Towards the front of the wheelchair - Decreases the drive lockout angle.
• Towards the rear of the wheelchair - Increases the drive lockout angle.
NOTE: TRECM or TAC Only - The ability switch must be pressed and released between each
movement of the drive lockout sensor to update the status displayed on the remote programmer.

Risk of Death or Serious Injury
NEVER operate the wheelchair or elevate/lower the seat while in any tilted/
reclined/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 vertical, DO NOT
operate the wheelchair or elevate/lower the seat.
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 IMME-
DIATELY 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.
9. Test the up/down tilt functions.
10. Verify that drive lockout activates at or beyond 20° of tilt.
NOTE: When drive lockout activates, the wheelchair should not drive and you should get an error
code (E28 or a series of flashing bars) on the joystick.
11. If drive lockout does not activate, repeat STEPS 1-10.
