Anyone know what "Heap error" codes mean? like 22E520: 22Ec Mine does this sometimes with the adapter for scanner control, in and out, and locks up the pro-106!! Then I restart and it will be ok until I touch a key! then do it again. I am able to use after tinkering with on then off again etc. etc. The other problem I have is when I download info from "psre edit 500" to a scanlist it will whipe out other scanlist info. I am able to figure out how to enable the scanlist now thanx 2u but I am unsure how to "assign" I can find my area's (groups) (citys) from srch and save and listen but I only have about half of what I want to hear. I upload the the entire Dakota County MN. (armer) system. Im still reeeel green! thnx for any info. Mike
