It’s a touch screen radio, pretty cool actually. Best bet would be to get on you-tube and type in Icom 7300 or icom 7300 controls. At that point you should have hours worth of videos pop up. Scan through them and then start watching.How do I get to current mode?
I would also do a google search for Icom 7300 manual. Several different links/options should pop up. Then just download a copy to your computer. This way you can learn two ways, by video and reading the manual.
