Well I am having an old age memory problem and I read the owners manual and can not find the answer so thought I would ask the pros. I use the APT in Pro Mode but when I turn it off and then turn it back on later it is back in Standard Mode. Is that what it is supposed to be doing? Somewhere in my mind I thought it was supposed to remain in Pro Mode. I am not holding the power switch down long enough to go to factory resets...that was my first thought. Just wondering if it is an ATP problem or my memory and mind playing tricks on me. Thanks for the help.
