"1/2" - "Rabota 1/2", next to "Peremena chastoti" on SA-2. It should make transmition on 75 km mode to be like in 150 km mode, as I got it right, but did it work on 150 km mode? When I flip it, the screen changes a little, but this mean nothing...

RAB.NA fo/2
It is an extreme rarely used feature of the Volhov.

While guiding a missile, it is not recommended to switch the range mode from 75km to 150km.
(switching from 150km to 75km is ok)

In case, when we are guiding a missile, and we are in 75km range mode, and would like to go to 35km mode, we do the following...
1, switch fo/2, leaving the range mode selector in 75km mode.
2, switch 35km at the I32V panel.
