Garmin 430W Com Setup Question

[bruceg]

Does anyone here know the trick for selecting the "Store Calibration" field on the com setup page?
On our 430W and one other that I've tried, that field seems to be unavailable. And it's a light gray color instead of white. Thanks!

You have to select right freq first.. It will be enabled for three frequncies only... Details are in the manual..
