UHD with Flex 400

Hi,

I’m trying to use UHD with USRP1 and a Flex 400 daughter board. When I
run a
gnu radio program (through GRC), I get the warning

UHD Warning:
Detected RX daughterboard Flex 400 Classic
This board requires modification to use.
See the daughterboard application notes.

However, the RFX Series Application Notes in the UHD manual (
http://www.ettus.com/uhd_docs/manual/html/dboards.html#rfx-series) does
not
specify anything that I can interpret as a “modification”.

Thanks, Sivan T.
