You will only get the "80 knots" callout if you dont set the bugs at all or not correctly.
So as a minimum you have to set BUG_2 to V1 speed
and BUG_3 to Vr speed.
Its very important that you use BUG_2 and BUG_3 for V1 and Vr. Dont mix with other bugs
If you do that correctly you will get "Positive rate , gear up" callout.
You can find the v-speeds in your FMS when you have entered perfomance data etc.
