MTS2000 Flashcode

I have an MTS2000 with unknown flashcode. How can I find out what version the flashcode is?

Assuming you have a display (model II or III)...

WHEN YOU TURN YOUR RADIO ON DURING THE SELF TEST, PUSH THE THIRD BUTTON DOWN FROM THE TOP SIDE RADIO ABOVE THE PTT (Press 5 Quick Press). IF YOUR RADIO HAS A DISPLAY IT WILL DISPLAY [Field Test Mode] S/N MDL # AND POSSIBLY THE FLASHCODE.
