Hi
today I tried to start my friends Kingtech 60 , first problem was the backlight of GSU , it was really hard to see , is there any hidden menu for adjust the brightness and contrast of LCD ? And the second problem was , after connect the batteries ( receiver and ecu ) the RPM in LCD fluctuate ( goes up and down , shows random numbers ) , but it works when test the starter and works very well when turbine is working ,how can I fixed it or its normal ?
thank you
