Question about Cobra PR-245/2 (7 Channels) 2-Way Radio

1 Answer

Cobra MT800 I have just been given a pair of Cobra MT800 which are I think similar to the PR-245. I need to turn off the Call sound so as not to alarm animals and birds that I photograph. Does anyione know a way of turning off the Call button sounds on both handsets? Thank you.

    Thank you but it is the actual 'Call' on my MT800 that I wish to turn off so that the other person does not make my handset alert the birds/animals. Can it be done? Thank you for your time.

Hello SSPD12,

To turn off the tones whch sound whenever you press a key do the following:

1. Press the MODE button until the music note icon on the display flashes.
2. Press UP or DOWN to select the desired setting (either On or Off).
3. Press MODE again to save or simply wait 15 seconds.

Hope that helps.

    Hello again SSPD12,

    Are you talking about the "Call" tone or the "Roger Beep" tone? The call tone should only be sent when you press the CALL button on one of the radios. This will cause the radio to transmit a two second beep to the other radio. There is no way to disable this function perse, but the tone should not be heard on every transmission, only when the other user presses the CALL key.

    By comparison the Roger Beep function sends a tone on every transmission at the end of the transmission. This tone is supposed to alert the other user that you are done talking and they can begin their transmission. The Roger Beep can be disabled:

    1. Press the MODE button until the ROGER BEEP icon on the display flashes.
    2. Press UP or DOWN to select the desired setting (either On or Off).
    3. Press MODE again to save or simply wait 15 seconds.

    Best Regards

Hi SSPD12,

Another potential "fix" for the problem that occurs to me is this: if you are not able to turn off the "call" tone you are referring to, you might be to solve the issue by purchasing a headset or earphone for the radio and using that when you are in the field. This would solve the problem because only you would hear the tone while you are wearing the headset.

Just another option for you to consider..

Best regards

This is a discontinued product, and at that price point, they're completely disposable. If not working properly, then toss and replace.
