Shutting Power to the FLEX-6400 from my Astron

Coming from a Kenwood TS-590S where I could just flip the switch on the Astron and **** power to the radio... can I do the same thing with my FLEX-6400? Or do I need to do a "proper" shutdown by pressing the green power icon on the radio?

Applying or removing voltage from the power supply is generally not preferred for any electronics, due to the risk of a quick inrush on startup, or undervoltage effects on shutdown. Some rigs keep some circuits running, even while off. That said, you -can- shut down from the power supply, but the TCXO won’t maintain accuracy, and the rig will throw an error message. Normally, not serious issues, but worth avoiding if you can. Power down like you would your PC or other expensive digital electronics.
