This is very useful when you want to narrow the scan in areas where numerous entities utilize the same trunking system. For example, if the police department, sheriff’s department, fire department and EMS all use the same system in your area you can program the identical trunk- ing frequencies on 4 separate banks. Then by manually storing their respective group IDs into corresponding banks (i.e. police IDs in bank 1, sheriff’s IDs in bank 2, fire rescue IDs on bank 3 and EMS IDs on bank 4) and setting the banks to the closed mode, you can choose which service you want to listen to. (See “Turning Chan- nel-Storage Banks Off and On” on Page 41.)
