Normal Operation: When new batteries are inserted or AC power is connected or RESET Button is pushed, the lights on the Printed Circuit Board (PCB) will blink in the following sequence: Red, Red (with solenoid clicking), Green, Red and Red. Green light will stay on. When the user enters the sen- sor beam's effective range, the Red light will flash one time on battery-operated flush valves and will stay on on AC-pow- ered models. If the user stays in the effective range for more than 4 seconds and steps away, the valve will activate (1)

flush cycle. The flush valve unit will automatically reset for the next user. When the manual OVERRIDE Button is pushed, the flushing mechanism will be activated without impacting the mode of automatic operation. On battery powered mod- els, the Red indicator light flashes when batteries are low.

Please note: Always push the RESET Button
