I have just downloaded the manual, and I’d suggest starting on Program 1. See how you go. Once you have a ‘feel’ of what you’re hearing/seeing you can start to adapt it to your needs.
Allow a minimum of 10Hrs (seriously) of focused practice before you put it away in the back of the wardrobe or on TradeMe.
You’ve bought a good machine, so it’ll be like learning to ride a bike without going through the training wheels stage.
Some think you should avoid auto settings from the get-go. I recommend starting in auto but make an effort to move away from any ‘auto’ settings as soon as you can.
Look forward to seeing what you pull up, trash included - we’ve all been there.
