To program a Uniden DC355N scanner to hear police activities, first, ensure the scanner is set to the correct frequency range for your local police departments. Use the manual to find the specific frequencies or codes used by your local law enforcement. Enter these frequencies into the scanner by switching to the programming mode, and then input the desired channels. Finally, save your settings and switch to the scanning mode to listen for police communications.
To program your Uniden BC170 scanner, you will need to consult the user manual for specific frequencies and codes related to your area. Generally, you can enter frequencies manually using the keypad or program them using software like FreeScan. Make sure to check the local laws regarding scanner use, as some frequencies may be restricted. If you're looking for a specific code, please clarify the type of code you need (e.g., police, fire, etc.).
