Why does my machine light come on?

[Country4ever]

I have a ResMed AutoSet Vantage S8. I've noticed occasionally I wake up in the middle of the night and the light on the machine is on. I'm thinking it might come on when something's wrong.......like alot of leaks, or not enough pressure, or something. But the LED readout doesn't say anything but the pressure and the dots for a good seal. It says nothing about this in my booklet. Anyone know why it would just come on in the middle of the night?
Thanks.

do you have cats that sleep in the same room as you. i have found my cat steps on my buttons which in return turns my light on.

No, no cat.

then yes it is probably leaking somewhere.as long as you are getting lots of air flow, i wouldnt worry about it, but thats just my opinion
