Troubleshooting
Step 1: If signal strength is low, attempt moving either the Coordinator, End
Device or both as close to the side of the vehicle as possible. If this fails to
improve signal strength, rotate either the Coordinator, End Device or both, if
possible.
Step 2: If Step 1 fails, connect the included x2 external antennas, one to the
Coordinator and one to the End Device. Antennas must have the same
orientation i.e., both pointing up or both pointing down, both pointing left or both
pointing right. Antennas must be installed on the same side of the vehicle
