where do i find the detailes ownwers manual on your site please

I just got a new CODE50 and am extremely pleased with. My problem is everything on the Gateway app works, but the GAIN, MIDDLE, VOLUME, and PRESET knobs on the amp don't work. I'm really pretty new to this so I'm not sure if something is wrong or I'm doing it wrong but every other knob works correctly.

is there a downloadable manual in Spanish language available for the CODE 25?

Hello, what is the warranty on the Code 50? Couldn't find it in the users manual. Thanks!

Is there a printable Code owner's manual?
