TM 9-2320-366-20-3 WARNING Two steady mode lights are an indication that the CTIS has disconnected operation because of particular inflation or deflation sequence has taken longer than limits allow (40 minutes for inflate; 20 minutes for deflate). Wear appropriate eye protection when working under vehicle due to the possibility of falling debris. Failure to comply may result in injury to personnel. NOTE Two steady mode lights indicates that system shut off with air pressure between modes. The CTIS may still operate including modes that are illuminated by manually pressing the desired mode. To perform deflate or inflate checks throughout this task, it will be necessary to perform the opposite function first from time to time so that a desired mode selection is available.
