I've never needed to switch to the higher range setting, but I suppose it depends on the rig.
This one is fairly easy to test though, the pads behave like an SPST switch, so you either jumper the center/left pads, or omit the jumper altogether.
(Jumpering the center/right pads will have no effect)
Try it with no jumper installed, then (if you feel the need) temporarily jump it so you can see the difference for yourself.
