scan of many sat positions

[sssboa]

Hi :wave:
I know it's lame question. :D
I meticulously edited my channel list from set-up scan of 28.2E. How will I scan another positions using motorized mount so that new channels from next satellites are added to the list and I not lose any channel that was previously saved in the list? I think I lost all non-28.2E channels after the scan of 28.2E. I have TM-5402HD and the manual is not too helpful.
Regards
Andrew

I do not no a lot about your unit

but, normally, there are menu options, that allow you to do a multy sat scan, rather than a single sat scan
