Flex 5000C Pre-amp circuit @ 160 meters?

Flex 5000C: is the preamp circuit not available on 160 meters? Works fine on all other bands. Must be a setting somewhere I can't find to allow it to kick in on top band? Any advice appreciated ....

    The 5000A does not have preamp on 160.

    The preamp in the 5000s rolls off starting after 40m, provides only minimal gain on 80m and is not providing any gain below 3.5 MHz, which is why it isn't selectable when on that band.

    10 Meters is opposite, the preamp stays on.
