CZ,
Try doing this manually. Select MENU, PROGRAM SYSTEM, etc. and get to a conventional frequency.
When you get to SELECT CHANNEL, hit ENTER or push the selector knob, turn the selector knob clockwise 6 clicks to SET CTCSS/DCS, hit ENTER or push the selector knob, then turn the selector knob. The choices are OFF, SEARCH, CTCSS, DCS and SET LOCKOUT. Since you want to search, select SEARCH and hit ENTER or push the selector knob.
At this point you can press the SCAN button.
When you're scanning and a transmission comes up on this conventional channel, a CTCSS or DCS code will display if there is one used. Unfortunately, you need to remember what CTCSS or DCS code displays because pressing ENTER does not store it like it does on the BC296D.
To store it, follow the directions above, but select CTCSS or DCS, hit ENTER or push the selector knob, then turn the knob until you get to the correct code, then hit ENTER.
Hope this helps.
