Version roll back

Is it possible to roll back to a prior version on a BCD536.

I recently updated and now my apco25 is not receiving very well.

Or is there adjustment to the receive for apco 25 stations.

Thank you,

You can revert back. Here is the link for the firmware updates.
Make sure you you put the FW into the Firmware folder than restart the scanner.
