To program a Cobra SR900 police scanner, you'll need to input frequency codes for the specific services you want to monitor. Common frequency ranges for police and emergency services typically fall between 150-160 MHz for VHF and 450-470 MHz for UHF. You can find local frequency codes through online databases or scanner forums. Once you have the codes, enter them into the scanner using its keypad or programming software.
