I have a Uniden UBCD436-PT. I live in Queensland Australia. I have been using Sentinel. I recently purchased Butel ARC536 Basic. I download from Radio Referance into ARC536 and save the lists. When I then write them to my scanner it appears on the scanner, but once I disconnect from the computer the scanner shows "Nothing to scan" There are no Service Types listed to moniter.When I the reconnect scanner to computer and open ARC536, there is nothing listed in the scanner. It just appears that the scanner will not register what is downloaded. I am not very tech savy. Could someone suggest what I am doing wrong. Thanks.
