When Tag 43 is moved to Tag 44, marked 625 VHF, the local distance control comes into operation on 625 UHF as well. Both 405 and 625 contrast controls function as well.

The set will still work on 405 VHF if the solenoid is disconnected or if a switch is fitted to it, allowing a choice of 405 or 625 VHF.
