Try plugging the foot control in and see if it gives you a Mode 1 option. I can't remember how I did it with my 440 (I now have a 730), but can you push on the area or the button below the area that it says mode 2 and get it to change? Like push the scale button a second time? As it says in my previous message, if it was turned off in mode 2 the last time it was used, that is where it would be set when it comes back on.
Good luck. The results of your FMQ don't change much with the different modes, just the amount of control you have with stopping and starting.
