Can't find Tools, System Admin, Network Settings, or DNS

I have just installed PIAF with FreePBX 2.10. I am trying to follow the instructions listed in First Steps After Installation. Step 2, “SET A STATIC IP ADDRESS AND CONFIGURE DNS” tells me to click Tools, then System Admin, then Network Settings. Later in the instructions it tells me to go to the DNS section of the System Admin module. I can’t find any of these from within PBX Administrator.
