Main Bang Suppression Adjustment - JRC JMA-9832-SA Instruction Manual

......Main Bang Suppression Adjustment....................................

is the optimum level in which the main bang suppression is adjusted so that the main bang
remains weak on the video.

on the short ranges may be cleared.
