2. Internal / External antenna switch
If you wish to use your 104-PRO self contained, without connecting
external antennas, please move this switch to INT position (default position).
If possible, use external antennas for permanent installation as these will
provide more accurate signal. After installing external antennas the switch
should be moved to EXT position.
