You are correct 100%. Their manual S*@Ks big time . It does not tell you how to do or set anything, (ie. as for the time it says this unit will show time,) it does not tell how to set the time . It does the same for everything! And then the dam thing shuts itself off by its self for no reason, so far it is great when it works but I am never sure if it will. Every time I put it on its like what will work & not work this time ??
