Unlocking throttle to use beta range

[glroig@hotmail.com]

Hi, 

I am using a PfC cirrus II console which brings its  throttle. It's USB plugged, not serial port. 

I have read the forums and have seen that to unlock the beta range I should assign a keyboard button for the thrust reversers. 

I have assigned it but it won't unlock. I'm not sure of issue, but could it be the console? 

Can anyone help with this issue? 

Thnx

G
