in the PC software, click on trunked systems tab, then select your system from the list at the top of the screen, then site details. The frequencies should be there. if not, they never transferred from the database to the scanner memory
PROBLEM SOLVED: step 1. click on scanner/sd card then scroll down to optimize scanner/sd card once that's done go to updates click on all updates and everything will load again. that's it!!! :O)
