I have a UHF 380-470MHz XTS-5000 model III FPP and after about 2 seconds of receiving a transmission it lets off a single low pitched beep. I can only test it on analog since I do not have another UHF P25 radio to test it with. The radio is not on scan and for the life of me I cannot figure out how to make it go away. The info from the service menu is as follows if it would be of any assistance to any potential troubleshooters out there.

Host Version: R20.00.01
DSP Version: R19.50.00
Model Number: H18QDH9PW7AN
Flashcode: 5A0083-101B07-5
Tuning Version: R01.09.04
Proc Ver: BRAVO122

I also have a video of it as well, thanks in advance to anyone who can shed some light on this problem.
