I have just picked up what is marked as being a Scan Monitor 208A by Pace. I have no owners manual or other information on it and I was wondering how I can determine what channels are on it and how to change them. At this point I can turn it on and get it to listen to the local weather and that's about it. Any help that can be offered would be greatly appreciated. Based on the scant online information I could find, it came out in 1973 and has a range of 35-55 MHz and 152-164 MHz.
