When batteries are inserted, the Vent will open and close its louvers, displaying the 3-2 light pattern, then lights turn off.
During Setup, lights will cycle in a pattern until the Vent pairs with a Gateway. This can take up to 5 minutes. After 30 minutes with no pairing, lights will turn off to save battery life. Turn on Setup Mode to restart Discovery.
When paired with a Gateway, the Vent will display its unique light pattern until Setup is exited, or 30 minutes (to save battery life). Vents will display their pattern any time Setup is entered, or batteries are replaced.
