In normal operation, the green LED flashes every 30 seconds. When a CO reading is required, the LED flashes briefly; during an alarm the red LED pulses and the audible alert sounds in a repeating cycle—four short beeps, five seconds of silence, then four more beeps—until the CO is eliminated or the unit is reset.\u003c\/p\u003e \u003cp\u003eFor reliable performance, regularly test the unit using the built-in test\/reset button and replace batteries as needed.
