SAFC help

I got this safc(no manual or instructions) for my car, and i hooked it up, but i dont think I'm tuning anything right. is there a site or help guide on how to use the safc and what everything means? Its the older model safc, im pretty sure, just black with black screen and green text, not like the fancy newer one. any help would be great. thanks :)
