I put "scan control in the Easier to Read Guide for your radio. Hence, it pointed me to a software program for your radio. Is this what you're talking about. Or, are you talking about the firmware associated with the radio?
This is how you check for firmware up date for the PRO 106.
Turn OFF radio, push & hold # 3 & turn ON radio while holding # 3 in, then let go of # 3. when done hit
scan. This will show the latest up date you have.
