  • Page 11 SYSTEM - (Trunked Operation Only) The term system refers to the particular group of station repeaters and set of group/special calls providing service to the radio. Radios can be preprogrammed to work in different systems by changing the System selection or through wide area roaming. GROUP OR SUBFLEET (Trunked Operation Only) A group of users share the same preprogrammed group identifica- tion number in their radios.

  • Page 12: Operating The Radio

    Each trunked system may also have a priority trunked system associated with it. When set to a system with that priority system programmed, the radio will check for the priority system periodically. If found, it will automatically switch to that system. The timer is reset every time the PTT switch is pressed to avoid interrupting a conversa- tion.
