How to Program a Scanner for Police
Programming a scanner to listen to police frequencies can be a useful tool for staying informed about local events. While the process can vary depending on the type of scanner you have, there are some general steps you can follow.
First, you will need to find the frequencies used by the police in your area. This information can be found online or by calling the local police department. Once you have the frequencies, you can enter them into your scanner. To do this, you will need to consult the user manual for your specific scanner model.
Once you have entered the frequencies, you can start scanning. To do this, simply turn on your scanner and set it to the “scan” mode. The scanner will then automatically search for active frequencies and stop when it finds one. You can then listen to the audio from the frequency.
