FortiAPs and AutoTX/Auto Channel

Hi Guys....I'm a stranger in this town, dyed in the wool Cisco and Meraki wireless designer/operator but I've been tasked with looking at a Fortinet installation. I'm pretty sure from RF indications that the channels and TX powers that the APs are set to is not being managed automatically (several interfering APs not changing channel/power when they can see each other). Is there documentation that will show me how to set up and manage Automatic Radio Resource Management? I know what I want to do, done it before on Cisco/Meraki/Aruba, and could probably fumble my way through if this was not a customer's production network, but I'm being a bit careful

Thanks for any help!
