i dont have either rad bikes here at home right now but on a lot of these displays you can hold down two buttons and get into a slightly deeper menu where you may be able to change stuff like that
or it may be you have to different controller/display setups if one of the bikes is newer 2015 than the other, rad has made quite a few upgrades/modifications to the controllers etc
good luck, i am sure if you contact them they will get back with you quick
