All three turn on all functions look like they work. Push the talk button it switches to transmission then release and goes back to receive. Have all three on the same channel.
Is there a way to reset them. Im new to 2 way radios.
How close are the radios when trying them. They likely need to be at least 20 feet apart to eliminate overload and desens. Check to make sure all three radios have the same “privacy” tones (or whatever Cobra calls them) or better yet, no code. I’m sure someone else will chime in with other ideas.
A quick search for resetting that radio came up with the following: turn the radio off and then hold the MODE and WX/UIC buttons simultaneously while turning it back on.
I have no idea if this works as I have not used that radio.
Do you know if they were part of a working set? We have had cases before where people bought individuals from things like ebay, but they had all be reprogrammed away from their original channels. If you have three, and none of them will talk to each other, then there’s very little a user can do to make this happen - apart from different programming. That may well be possible, if you can find the software and the cables, but three failures suggests they are not a working set, rather than a fault as such.
