I am trying to get a handle on the UHF radio. When I put it in Preset mode, and choose a frequency, and then lift the cover and push the red button to save it, does the displayed frequency always stay on what I input? For instance, in preset channel 1, I had 251.00. I switched to preset Channel 2, and input 261.00, and clicked the red button to save it. Of course, the display now shows 261.00. However, when I switch back to preset channel 1, it still shows 261.00, not the 251.00 that should be channel 1. The actual frequency is correct, Ithink, as I can talk to whoever is on 251.00, but my display still shows 261.00 on the actual radio. When you switch preset channels, does that display on the radio not change with it?
