No.17448 Kale Developer Mar 1, 2020, 22:43	Some code has to be patched out for this to work (see below). The program remaps button 2 and 3 to button 1, so you can't enter the above sequence. This really applies to bjtwin only, which has a buggy routine for the service mode. May as well make some rewording of the note but regardless this bug report is a BTANB to me.
