Actually, Jim responded. I use the 5R, so I followed his instructions just to see the result. I stumbled a bit, because "scroll down to the Detailed Menu Reference" is really "Menu Definitions - Detailed", and my brain was programmed to skim for "Detailed". Persistence helped ;-) But sure enough, the answer is there. Thanks to you both. I updated my notes to "UV-5R scan options: TO=pause on channel; resume after preset time. CO=stop on carrier detect; resume when carrier drops. SE=stop on carrier detect; resumed by user." ...but it has been a while since I used scan on either of my 5R models, so I don't recall what happens with SE. I'll have to read the manual and test. Does it: 1. When SE is active and stopped on a channel, and the user presses SCAN, radios will pick up the scan at the channel point following, and resume scanning. 2. Go back to the beginning of the scan programmed list, and begin again. 3. Start the scan with the current channel, which may still be active. In this case, the user must manually step ahead, then press SCAN. ISTR that the 5R will resume scanning (SE mode) with the next scan channel, when the user triggers SCAN. ~R~

I haven't seen anyone answer your question. TO is stop on search and resume after preset time. Usually 5 sec. CO will stop when detects carrier and resume when carrier drops and SE will stop on signal and remain there until acted upon by user.

Hope this helps you understand the 3 choices.
