Actually I don't think you even need to toggle; you're just removing a jumper that shunts the 11 meter band. Once removed, you've got the full range open. I could be wrong, but this is how most of these jumper removal mods work.
However, just to clarify, the bands/modes that this radio covers in the 10 meter, require an amateur radio licence to use; and most, I believe, require a general or higher (unless used in an emergency situation); and even then, there's not a ton of activity on 10 meter these days. When there is activity, I think most is done via SSB or CW modes, which this radio does not do. You'd also likely need a second antenna that is tuned specifically for 10 to make good use of it.
Technically speaking, this radio isn't legal at all for use on 11 meter/CB either, but the FCC doesn't really seem to regulate or care about 11/CB, so there is very minimal risk in using this radio for CB (especially given how this radio is openly advertised for use on CB!).
So to make a long story short (I know, too late!), as was the intent of this post, this makes for a great little CB radio; and I think that is where it's place really is. As otherwise, it kind of makes for a lousy 10 meter radio.
