User Setup e- The T-FBK4 will detect and remove feedback by placing notch filters on the proper frequencies. Continue to slowly raise the gain until all feedbacks have been eliminated, then exit from SETUP Mode by pressing and releasing the CLEAR/SET UP button quickly. If all 24 filters have been used in SETUP Mode, the SETUP Mode is left automatically and no more filters are available in LIVE Mode.
