Turn off oven fan on Shimadzu GC-2010 using keypad on front?

[pacerlaser]

What is the simplest way to turn off the oven fan on the Shimadzu GC-2010 using the keypad on the front? I've used Agilent GCs for years but this is my first time with a Shimadzu and I can't seem to figure out how to turn the column fan off using the keypad on the front. Any help is greatly appreciated!

I believe it's under the COL menu, then use the PF buttons to find "Fan Off" you my need to use the one that looks like a menu on the far right to get to it.
