First, ensure that the scanner is properly powered and that the antenna is connected securely. Check the manual for specific instructions on how to program or scan for frequencies, as different models have varying procedures. Additionally, confirm that you're within range of active frequencies and that the scanner is set to the correct mode (e.g., VHF, UHF). If issues persist, consider resetting the scanner to factory settings or consulting the manufacturer's support for troubleshooting.
