Conclusions: Daifuku concludes that with the following measures implemented, it is possible to operate the CSC-500 with an FCC-compliant feeder radio system: • Separate the feeder line from the metal track • Minimize the distance between the feeder line and the vehicle modem The transmission field strength was observed to fluctuate depending on the surrounding environment and measurement position (inside the track vs. outside the track for example). For this reason, field strength settings were adjusted at the optimum (field strength most stable) location on the test line, which was point A. DAIFUKU AMERICA CORP. DAIFUKU CFA—K. Ueda/M.
