IMPORTANT FCC REGULATORY INFORMATION
The AMP2440P and the YDI WLAN 2400 WLAN cards must be professionally installed. Table
(1) shows the FCC approved antennas that can be used with and without the YDI AMP2440P.
It is the responsibility of the installer to ensure that when used in the United States (or where
FCC rules apply) under Part 15 regulations, only these configurations can be used.

. The antennas must be installed
such that there will be no person closer than the specified distances in front of directional
antennas or directly beside the Omni antennas.
Note: 20cm is the minimum distance regardless of what the actual calculation of the density
shows.
