DDJ 400 CDJ mode. Still scratches

I learnt how to switch from Vinyl to CDJ mode. It's fine, I know to use keybord settings.

When I'm in CDJ mode everything go ok if the song is playing but if I press pause, any jog movement produces scratches as if it is in vinyl mode. So if I need to move back and forward along the track and I forget to turn down the volume a embarassing noise will come up.

I would like to avoid any scratch noise as long as I am in CDJ mode, is that possible?
