Scan Function Ray 70

[Sculler]

I have a new Ray 70 VHF and cannot for the life of me figure out how to set up a custom group of channels to scan.

The scan function works fine when I set it to scan all channels + 16. I would like to set up a small group of channels including 16 to scan.

Could anyone give a step by step process for saving channels to scan and then selecting those channels for scanning? I have the owners manual and cannot figure it out. I've tried calling support but gave up after being on hold for over a half hour. Also have searched here without luck.

Thank you for help if any one can walk me through the steps. Seems like it should be very simple!
