ok, let's try object ID#, I deleted object ID #1, #2, and #3. When in manual mode I can push up and down arrow key to walk through my list of ID numbers. ID numbers 1, 2, ,3 are not there. My ID numbers start at 4 and continue up from there. If I go into manual and enter ID #1 it display's Object #4 freq. I can not program into Object ID #1. This may be just the way this scanner is I can't find any information on assigning freq's into Object ID's of my choosing. I have not got into programming with software, maybe this is the answer.
