LCL Beauty Steamer Question

[CityGirlLuv]

I just assembled my steamer and I'm just trying to figure out what the yellow button behind the steamer means. I assume the red button is the "power" button, but I'm stumped on what the yellow one is suppose to represent. Here's a picture of what I'm talking about: http://lclbeauty.com/proddetail.php?prod=PRO-1037A-LUSTR4

Nevermind, I assume it's just to add extra power to it. I'm just going to leave it off.
