What I suggest is if you haven't already done so, connect your scanner to a PC and take a copy of it's SD card and save in a couple of places. That way if something goes wrong you can copy it back to the scanner and be back to square one.
Then using Sentinel read the scanner's dataset, save to PC and disconnect the scanner.
Basically the programming hierarchy with the 436 & 536 is System > Department > Channel Name. You create them in that sequence.
Using Sentinel, have a look at the UHF CB data In the Favorites Lists (FL). The
System is "Citizen Band(99"), the
Department is "Conventional" and
Channel Name is "UHF-CB".
Note the type of data in each, which will give you an idea what sort of data you need to enter for a new Favorites List "Airband" entry.
You can create a new (additional entry) in the Favorite Lists (FL) by highlighting Favorites Lists then Edit > Edit Favorites List > New Favorites List.
Given it a name e.g. "Airband". Click the green "+" in the next window, enter Airband as the System Name and "Conventional" as the System Type.
Then using the green "+" symbol in the Department and Channel windows, work your way through entering the required data.
Then write the new FL to the radio and check it out. If you have another scanner, maybe enter one of the frequencies you programmed into your 436, and if all is well a transmission should be received on both scanners
