This Hyper realistic Motorola MXP600 is scripted to have the screen blink to show someone talking on the radio and has sound to match it. Another cool feature of this product is that it comes with a GUI that enables the user to change the collar number and division displayed on the screen. 

Note: You will need to change the Channel to whatever you need it to be.

Just follow the instructions provided on the Asset in studio to make it work.
