The GRE PSR-600 GLOB menu stores all of the radio-wide settings used by the scanner. The GLOB menu allows you to tweak these settings to your liking. The default settings will work fine for most users, but most users will want to use the GLOB menu to personalize the radio to suit their individual tastes. The active parameter is always the middle parameter and is indicated by a flashing “:”. The entire GLOB menu is shown above. Note that some GLOB parameter changes do not take effect until the GLOB menu is saved. Also note that the original factory settings may be reset at anytime.
