XPR5550 Dual Knob Feature

A quick video on how to enable and use the dual channel knob feature on your Motorola XPR5550 mobile radio. This should also work for the XPR5550e - though I am not sure about the XPR4550 as I've never used one.
This allows you to change channels within the zone you are sitting in, without having to use the buttons. This can be enabled using the menu on the radio itself, or in CPS.
Having voice announcement set with this would be a huge help, allowing you to change channels without even looking at the radio!
There are two ways to get this set up: CPS or from the radio menu itself, here is how to do it from the radio menu:
Open the menu on the radio and head into Utilities, then Radio Settings
Get into Dual Knob
Set it to Volume & Ch (Channel)
Exit the menu
Push and hold to change channel, then push again to set the channel
Profit!
