Flap 1, 2 and 3 can all be used for departure as per your company perf manual. Flap 1 will give you 1+F. If you use Flap 1 for departure only S speed is displayed. If you use Flap 2 or 3 then S and F speed will be displayed. Clean up is from Flap 3 straight to Flap 1 when using Flap 3 for departure. At my airline Flap 2 is standard, Flap 3 used on short runways, Flap 1 used on runways 2500m or longer.
