Don't know, have only either captured a frquency during a search or used the laptop to enter a number of frequencies. Might be an idea to contact your supplier and make then earn their profit !!
I had a hard time programming my Whistler 1040. The manual is useless, and my computer doesn't recognize the programming cord that came with the radio. I was ready to return it. I found a video on Utube that explained it perfectly and I was able to program the radio finally.
Just search Utube or google for Programming Whistler scanner.
