Problems Changing Channel on Yellow Dongle

[BaysianLogik]

My team was just at a scrimmage, and everyone had some major issues changing their channel using the yellow dongles on the 2005 controller. I believe we eventually got 3 of the 5 robot's channels changed, one robot used last year's RC, and the last one (us) use channel 40, the default channel. I don't think anyone was able to do it with their original team number, we had to randomly assign numbers. We were using the step-by step process found in the schematics for the dongle, but they didn't seem to work, and had to finagle our way though it, so I dont think anyone at the scrimmage walked away knowing exactly what we had to do to change the channel.

Does anyone have any advice on changing the current years RC to use a different channel?
