Voltage conversion of dCS 954 and 974

[Georgiosnz]

Hey guys

Just want to check if you guys know how to convert operating voltage of dCS 954 and 974. I see there is a red switch underneath 954 so I guess all I need to do is flipping that without even change fuses, but 974 doesnt seem to have such a switch at the bottom. Any ideas?

Thanks for that, not sure what “option code” means though. How about dCS 954?

Nothing very conclusive for the 954, it is just specified that the device is delivered with a mains voltage which corresponds to the country of destination, and that the device can be updated by an official seller if necessary.
Open it and look inside.
