I would check your control channel for the romeo tower 868.5125 and 868.1625 for the backup and main romeo tower frequency are programmed into the scanner. Also you can check to make sure you are picking up the control channel at your location. When you pick up something on the above frequency press "man", then "F2", then "F3" to analyz the control channel. You should hear the control channel from the speaker and see data coming from the channel and see a 99% or lower number in the bottom left part of the LCD screen. If not you can press the down arrow on the multi function control to scroll through the channels you have programmed in until you get to one that you can hear the control data and see the 99% go active and the data sound.
You need to be aware with digital scanning you may find dead spots at your location. I have helped people program scanners and found that they needed to move the scanner six inches and all of a sudden it works just fine. I have helped others that could not receive anything at home because of interference from cell towers or because they just didn't have a tower in range using the stock antenna, but we would drive a mile down the road and it worked just fine.
You can also search for control channels in your area by using the search function to see what control channels you can receive: Keep pressing search until you get to "public safty". Then press 0,1,2,3 to turn off everything but the 800MHz freq. Then press the down arrow so you start at the higher freq and go down from there. Write down the freq you receive it should say P25: xxx (the tower number) mine shows P25: 794/ 868.925000 for the Holly tower in North Oakland County. Once you figure out if you can pick up a tower freq and what it is, that is the first step. If it is different that what you have programmed in you can add this new freq to your system programmed.
You can also search for new talk groups by programming a wildcard object so you hear everything coming accross the tower/control channel instead of just St Clair Shores so you can make sure your programming is working instead of just a few talk groups that may not be real active.
Let me know if you have any other questions.
