Modern Vespa

My MP3 300 2010
clock flashing 4 x 0
Press left button and get 3 x 0
But the set button doesn't advance the time

It's doesn't scroll through the hour , minute , date

Is there a reset button to ignite the clock into correct movements through set up steps

Tried disconnecting the batt for a couple of minutes???

Disconnect battery and left for 5 minute. Reconnect. Clock now working. Reset it and all ✅

Thanks for advice , it worked 😊
