Lightbar

The Lightbar diagnostic test initiates an illumination sequence of all of the LEDs and the text win-

dow, followed by a brightness control sequence. This allows the verification that all lights on the

CenterLine lightbar are working properly.

To start the Lightbar check, go to <TOOLS> and press Enter. Scroll with Up or Down until

<LIGHTBAR> is displayed in the text window and press Enter. The illumination sequence should

start. When test is completed the lightbar displays <END>.
