If you have a Phoenix Package, then the Medallions appear under your profile to be selected. Once you do this, they are "locked in" and appear in your cockpit item inventory as a Hanging Item. Just go to your Mechbay, select the Mech you want, go to Cockpit Hanging Items, and then scroll down the list until you see the medallion. The Hanging Items are displayed haphazardly though, so they can be a bit frustrating to find.
If you don't see your medallion, then try contacting PGI Support. Also, you may want to check your other Mechs to be sure that you didn't already equip it and then forget about doing so.
