Multi function gauges - manual?

Is there a web site or link that explains all of the functions of the yami multifunction gauges? Like what do all the bars mean flashing ect. I am new to the yami and want to understand what they offer.

Thanks

The three bars at bottom of tach are for oil level on a 2 stroke engine, right bar indicates oil level in oil injection tank is ok, center bar indicates need to add oil to tank, left bar indicates low or no oil(signals warning buzzer and engine rpm reduction). If it's a 4 stroke engine it just has low oil pressure warning. The overheat light is on left side of tach which will light when engine overheats.
