      If your Uniden Scanner won't stop scanning, consider these possible solutions: 1. Adjust the squelch threshold. 2. Check the antenna connection. 3. Examine whether many channels are locked out, as this reduces the scanner's ability to find an active channel. 4. Review each channel's frequency to confirm it is correctly stored in memory. 5. It's possible that none of the programmed frequencies are currently active.
