When your swinging the coil ,i look at the read out and it is far left on iron,never made a sound.It will continue to be silent until i hit the operate button. Seems like it will sense iron and lock it self into iron and not sense anything till i hit operate
My machine does the same thing I just figured it to be a reset to the original (current hunt settings) so Ive become accustomed to it and now hit the operate button almost automatically.
May your detector always find the good stuff! Trapper
