Flashing letter A/B

Sorry guys, I'm new to the 737NGX thing, so will keep pestering away..LOLAs I posted in another topic, I cannot engage VNAV. So I adjusted speed at cruz, but now I am getting aflashing B next to the speed. Before, on another tutorial attempt I had an A. Anyone? Thanks! Mark

This usually means your speed window is set too low for your phase or configuration of flight I believe; increase the speed in the window to see if it stops flashing.

Thanks Sean! B must mean too high, and A too low... Thanks again! Mark

A is the underspeed warning, 8 is the overspeed warning (you will see the overspeed warning if you set a speed over the correct limit for current dirty config (i.e. with the gear or flaps down etc) Al
