We are trying to reset level in our 2006 Allegro class A. We followed the instructions to set manually but the board would not respond as indicated in the instructions. It says turn unit off, then press ext 5 x's, ret 5 X's.... the unit will respond by blinking all LEDs slowly. We got No lights at all. (Does it make sense that if you turn the unit off it would still blink?) Then press all 3 X's, then turn the unit back on and retract all..
