travel locks location?

[sudsguzzler]

I'm still fairly new to this RV thing and I have warning messages about securing the slide out travel locks, but I don't even know where these locks are? I have scoured the slideout and don't see anything that would secure the slideout. Perhaps the previous owner removed them or broke them off, but perhaps someone can give me a good idea where to look for them. I have an 06 Tourmaster T36.
