Question  When I tap on the foot switch the light does not stay on any more, it will only work when I hold the switch down with my foot.

This is a feature on the device that we call 'Alternate momentary footswitch action'. To enable or disable this, power up the unit while holding the 'Tone Button' until the Harmony LED flashes twice. The unit will remain in this alternate mode during subsequent power-ups until the procedure is repeated.
