Query: Great technology, but it doesn't work

In setting up the Midland 74210 weather radio, I visited the national weather service web site to find the county code for my home. This would allow the weather radio to be activated only for weather watches and warnings in my area. At the national weather service web site, I found a statement that several users had reported trouble with the Midland 74210 weather radio.I, too, experienced trouble with this product. It is not responding to SAME broadcasts in my area.I also found the user manual to be confusing and unclear. There are several sections of the user manual that have been modified by having printed changes pasted onto the orignal pages. Apparently, the user guide is a work in progress.
