Can I use the same Sentinel settings (Favorites lists, etc.) that I am using for my 536 for a SDS 200?
You can use the Favorites lists for either model for the other one. Favorites lists can be shared between the 436HP, 536HP, SDS100, and SDS200.
Be sure and use the correct "target model" for your lists. The base information (System type & Name, Departments, & Talkgroups) are used by all four scanners. However, if you set the target model for the SDS200 before editing a list, you would then be able to set or edit the Site NAC, and filters. The SDS100 & SDS200 are considered as separate target models because of the differences in their displays, and some of the other options. The original, default, "Preset" profile works for both the "x36HP" scanners (436HP & 536HP).
I use a separate profile for each scanner. While there is no difference in the Favorites lists between the 436HP & 536HP, by using a separate profile, I can set different sets of Favorites lists to load. All the lists can be used on any of the four compatible models, but there are differences in what I want to load, and/or monitor, for each model.
