Chapter 5. Configuration Menu

After editing Map A, press Enter to record the Map A set- tings and activate the selection fields for Map B. Use the same operation to edit switching time for Map B.

When ESF is used with an FDL channel between units, the units automatically coordinate the automatic map switch by sending a map switch command from end-to- end over the FDL. Only one end needs to be set to AUTO for this to work.
