:11:32
Look at the colors change.
:11:45
Boy, that's fast.
:11:53
This tells you the oxygen
up here, right?
:11:56
Yes.
:11:57
So it's at 21.
That's good.
:11:59
Now, if that gets below 19,
then it's...
:12:03
What's the number
you watch for?
:12:05
It's 19.
It's good also.
:12:08
It's good.
Yes.
:12:09
But if it gets below what?
:12:18
Does the battery sound okay?
It sounds sluggish like that?
:12:22
- That's normal?
- Yes, it's normal.
:12:24
Now, if you have
a real emergency
:12:26
and everything fails,
:12:28
I heard something about,
:12:30
you can disengage,
drop the main battery?
:12:34
Just...
:12:35
Yes, we have many possibilities.
:12:42
I hope we never drop battery,
because it's very expensive.
:12:48
How much?
:12:49
It's $250, 000, I think.
:12:55
I mean, would you take a check?
