5Ghz AP Lite GPS Sync?

We purchased several AP lites in order to utilize GPS sync in a high interferance area. While configuring them, we noticed the Sync options are all grayed out. Is sync not available in the Lites? Or is there another setting I'm missing in order to get them configured properly?


Please make sure that at Configuration->Radio page, under Synchrnization, you have selected the appropriate Sync source (GPS, CMM4, or CMM3). Sync is only supported in TDD mode, with fixed DL/UL ratios (75/25, 50/50, 30/70). This can be configured at the Configuration->Radio page, under Scheduler.
