The Swann website says it is the alarm LED (this is a new feature that is not on mine---it is so loud that this is really unnecessary). The small green light is a low battery light and there is a button to test the battery. I was hoping the red light was for testing the alarm which on mine can only be done with water and then you have to quickly remove the batteries to stop the deafening sound while it dries. Off/On switch is on the left and High/Low volume switch is on the right. This is loud and effective. I have 3 and intend to buy 2 more.

the red light is supposed to stay on, thats fine. but the sound going off in 1 hour is not normal, I get at least 2 hours on mine. I think you got a defective unit

The top "red button (not a button though) lights up. I guess it would be like a "click indicator". It flashes with the music.

the red light is a pilot light that stays on as long as it is plugged to the power circuit. if you wish to turn it off have to unplug the unit.

The red light should not be on. Check to see that the filter is in properly or read the owner's manual.

There is a faint red glow visible when looking into the end of the IR illuminator when it is switched on. You can't see it from very far away though.

any time the unit is plugged in the red light will come on. After the unit is plugged in a few minutes the red light will go off and a white light will start to flash. The white light flashing indicates unit working properly. If red light stays on or comes on unit should be unplugged then plugged in again to reset. If red light does not go off unit is bad.

There is a red light that comes on during use. It will go off shortly after you hang your phone up. It does not go on until you pick up the reciever.

David if you are getting the logic board for your unit it doesn't have a light on that part. The light is on the other end of the unit. Make sure you put a surge suppressor on your unit, they are very sensitive. Hope that answers your question.

The red LED let's you know that the unit is drawing power (either from the battery or the cord, whichever you are using). The other one is actually a light sensor. It works only when the unt is on battery power to extend battery life. It turns the unit off when its dark because t assumes you must not he there to enjoy it.

The top button should light up the screen. If it's not lighting up the screen there may be an issue with the unit.

The red light indicates the water heater is "on". When the red light goes out, it is not heating.
