Question about Cobra 22 CHANNEL 2-WAY RADIOS

Cobra PR4700WX -none of the controls work

Is there a common fix for this? When I turn the unit on, no matter what button I press, nothing at all happens. Is there a lockout that's happening or is this a more serious problem?

    Thank you for the troubleshooting assistance. Based upon what you wrote, I guess I'll be taking it in to have a technician look at it, as none of your suggestions changed the behaviour (or lack thereof) of the radio.

If you find that the LOCK/MODE button does not correct the problem, I have discovered that the microphone button on the inside has a contact patch mounted on the board. This contact patch is like a piece of scotch tape with a metal dot in the center this slides off to the side and leaves the MIC deppressed continuosly which in turn will lock the radio. I have found this on several radios. Once you center the patch place just a small amount of super glue to the edges and yo will have no more problem

Your suggestion to check the alignment of the tiny disk on the TALK button switch was spot on. I was ready to throw away the radio, but five minutes of tinkering and it is working like new. Thanks!!

Hi,

Your concern might be a simple case of "the radio is in locked mode" which can be verified with the presence of a padlock icon in the uppermost row of icons.

If it is so, turn it off by pressing the Lock/Mode button for a couple of seconds or till you hear a double beeping sound and/or the lock icon disappeared.

If there is no lock icon and none of the buttons will work, try to do a hard reset by removing the batteries and try again.

If none of the above will be corrective, your unit may require the services of a qualified communications technician since the problem may either be firmware or touch pad/logic circuitry.

Hope that this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

I want to thank jimp19550 for the tip ( on the microphone button on the inside has a contact patch ). That was the exact problem on my radio. I re-centered the contact and it was FIXED !!!

My phone is frozen! It is stuck on this msg. "Samsung SGH-T249". No matter which button I push, nothing happens. It will not turn off, nor can I make outgoing call. The screen stays...


Press and hold the power button until the unit turns off. Sometimes it takes up to two minutes to turn off. If you cannot get it to turn off using the power button, open the back and take the battery out. Press and hold the power button for sixty seconds with the battery removed to reset the unit. Then reassemble it and turn it on. This may not solve the problem on why your screen is getting stuck but it will reset and allow you to attempt to restart it.
