Boss DD-3

Hi,

I have a Boss DD-3 and when I turn the mode knob any where to the right of the M 200ms the pedal light turns off but it does turn back on when i press the pedal down.

So basically the L 800ms has a hold function on it?

Is this normal? and is there a way to turn this function off?

As i thought that the hold mode was only meant to be able to be used when the mode knob is turned all the way to the right pointing at HOLD.

Thanks for your help
