help with zenith 8s463/5808

[sweitzel]

Hey all,

I've had this Zenith for a number of years and it plays great after a recap. A while ago a friend dropped by with his toddler daughter who took great interest in pressing the station preset buttons on the front. Now I cannot for the life of me figure out how to return to manual tuning. Turning the tuning knob does nothing but I can press the station presets and one or two that are actually tuned correctly pick up a few local stations. Is there a trick to enabling manual tuning again?
