With the V-One Callout, I can only suggest that you made a mistake with an entry in the panel.cfg, or you did not put all the files in the correct folder so that they work correctly. I do not have the V-One Callout gauge installed in my 757, so I can't help you any further. Sorry. :( I see. It's fine, I can handle with that, it just to make it more "realistic." Anyway, thank you Markoz.

If you perform any update or repair to your 757, your V-One gauge will be removed.
You will need to re-install the V-One gauge again.
