I played around with mine and found that A button is Arm/Disarm. B button is panic. C button I am not too sure about, but noticed that when you press it, starts lights to flash and press again to stop them. Maybe that is the remote hazard flasher button???. Couldn't seem to find a way to adjust sensitivity or loudness of alarm, so not really sure if this is possible. For the others who were wondering how it was installed in the storage tray under seat, photo attached. It is basically a rubber insert that fits into tray and the alarm unit slips into the front of it. There is also an empty box fitting next to where unit sits, but there is nothing in it, so not sure what this is for other than to take away more space from the tray. Unfortunately, I had a Xena disc lock I carried in there, but now that will need to find another home since there is no more room.
