After some time S/A506 will show caution, then attention and finally clear aspect. For all this time S1 and S39 will show danger aspect since they are now in manual mode.(‘A’ marker off) as different from first condition. Now the route can be set manually only. This is the main difference between an automatic signal and manual signal.
If suppose advance starter (S/A 506) shows caution aspect. Then after setting the route for starter (S 39) will show attention aspect and after setting the route for home (S 1) will show clear aspect.
