Been meaning to ask this for a while. Is it just my machine or is it common to all F-75's that after reset, if you turn the sense above 87, you hear a threshold tone? If I turn the machine off and then turn it back on, without resetting, the threshold is gone. By the way, I can only hear the threshold in 3, 3H, 4, 4H and DP. Seems that 1, 1F and 2F aren't affected.
