cinetj Posted July 15, 2022 Report Share Posted July 15, 2022 Hi everyone, Today I tried to put an old UCR 401 to use again after a while and faced the following issue. The pilot tone indicator keeps blinkIng and the CHECK FREQ appears as well even though the RF level indicator is full. No audio. I've tried this with a smqv and a lma transmitter. I've doubled checked the frequency, tried different ones, but still nothing. Compatibility mode is at 400 which should be fine for both transmitters. Am I doing something wrong or is the unity really defective ? Quote Link to comment Share on other sites More sharing options...
gianlucaD Posted July 16, 2022 Report Share Posted July 16, 2022 Bypass the pilot tone, holding menu button and pressing Up arrow. Doing this you can understand if it’s a pilot tone problem and you can probably still use your receiver. Hope it helps Quote Link to comment Share on other sites More sharing options...
