I can suggest some resources that you can use to find the frequencies you're looking for.
One option is to check the website of the Chippewa County Sheriff's Office or the local government website for information on radio frequencies used by their departments. Another option is to visit the website of the Federal Communications Commission (FCC) and use their online database to search for radio frequencies assigned to Chippewa County.
You can also try searching for online forums or groups of radio enthusiasts or scanner hobbyists that may have information on frequencies used in the Chippewa County area.
It's important to note that you may need a license or permission to use certain frequencies, and it's always a good idea to check local regulations and guidelines before using any radio equipment.
There are a few things you can try to troubleshoot this issue with your 2013 Chrysler 300c's Uconnect Bluetooth system:
Make sure that your phone's Bluetooth is turned on and that it is in pairing mode.
Check the Uconnect system's settings to ensure that Bluetooth is turned on and that it is set to discoverable mode.
Try restarting both the Uconnect system and your phone to see if that resolves the issue.
Check the vehicle's manual to see if there are any specific instructions for pairing a device with the Uconnect system.
If the above steps don't work, try clearing the Uconnect system's memory of previously paired devices, and then try pairing your phone again.
Check if the software of the Uconnect system is up-to-date, if not update the software.
Try deleting all previously paired devices on the Uconnect system, and then try pairing your phone.
If none of these steps resolve the issue, it may be a problem with the Uconnect system itself and you may need to take your vehicle to a Chrysler dealership for further assistance.
Usually because the purchaser didn't read the instructions or because the instructions are badly written from Chinese. This is an eBay special. I wrote this Tip on connecting Bluetooth devices which mentions the step that is always missed.

Question edited for clarity.
Question moved from Cars and Trucks to Intercoms.
Contact the maker. It is likely that the buzzer sounder has failed, or the power to it. You say you "looked at the wiring diagram", I couldn't find one. I guess you meant the 'circuit board'.
