Does anyone have experience with this model of TBC, or could someone point me in the direction of a site that sells an operator's manual?

I recently picked up a FA-120 and do not understand what some of the settings mean and how they function.

For example, the unit contains a proc amp, and one of the settings is video. This video setting displays a number range that can be toggled through. 00-255. I have no clue as far as what this should be set at.


Here's a link to a data sheet on the FA-120 which includes a block diagram at the bottom:

Any insight regarding this model would be much appreciated. Thank you for your time.
