Wouxun KG-UV7D Programming Question

I received the Wouxun KG-UV7D and really like it. One thing: I can find very little documentation on this radio. The only thing was a YouTube Video by Ham Radio 2.0

I got this for the 220 band. I like to program on the radio from the front panel. I did get some 220 repeaters in the memory and notice a ± at the top of the screen. Is this normal?

I have a BTech UV-5X3 that shows the ± as well. Would love to find some info!

Well I kind of answered my own question. BTech responded very quickly through Amazon and said it was because I had programmed an offset for that channel. But I’m still curious about documentation for this model.
