trunked highway frequencies

Trunked highway frequencies are preprogrammed for each state. When the scanner finds the control channel data, the scanner begins to find any active IDs. If the scanner finds an ID, it appears on the display and you hear it. If you press e while monitoring an ID, the scanner will check to see if any other IDs are active. If none are active, scanning resumes. When the scanner finds a control channel, it will stay on that control channel until reception of the control channel is lost. To force the scanner off the trunking control channel, press DATA. If you press d while a talk group ID is active, the frequency where the talk group is active flashes on the display. If you hold down d for two seconds, the ID and the frequency alternately appears on the display. To return to the normal display, press d again.
