[amsat-bb] Unattended FoxTelem Question

Does FoxTelem automatically check for new Keps periodically, or only upon startup? I have an unattended station running on a Raspberry Pi, and I'm wondering if I shouldn't close and restart FoxTelem every couple of weeks to refresh TLE's. Scrolled through the command terminal and didn't see any updates occuring, but you can see keps being updated upon startup.
