Factory Reset Button Combination

I am disposing of my pristine 18-month-old SA30 and want to perform a factory reset for the new owner. How do I do this (preferably without having to connect via an external lead)? An Arcam YouTube video https://youtu.be/0IbTOmDXkmU?si=oxbqkLda8rYfjC-1 gives instructions for Arcam AVRs but doesn’t correspond to the buttons on the SA30. Help!

You can just do it from the menu, using amp’s display.
In the menu you should find “system reset” and “network reset” options. You need both, as they are for separate modules.
Network reset is more important, as this is where all your streaming services settings are stored.
System reset is just for things like maximum volume, inputs etc, so related to analogue part of the amp only.

Please be specific how it is done from the menu by specifying button sequence.

Thank you.
