Just got a SDS 100 and has several issues nobody has been able to help with at Uniden. Volume control only toggles between 2 numbers Ie: 78 87 78. When you go into menu it will only toggle the first two sub menu's will not go down the whole list. Was able to get California loaded and when it is scanning has a crackling noise. No more in stock so can't get a replacement can only return it. Is there a way to just wipe the whole unit and reload complete Firmware to see if it is a software issue vs hardware?
