If you look on the awning side somewhere between the back door and the axles, there should be a hole in the skirting, that's where you insert the crank in the manual slide mechanism.
As for the awning...I never myself experience this...I saw something in the manual about it, but can't explain because I'm not sure enough.
Personally , I'm not a big fan of electric awnings, I much prefer the good old manual ones, sturdier,stronger awning arms.
I had 2 2604's...any other questions don't be shy.
