Note: The transmission diversity function is implemented for this
product. For WLAN card (Model: BCM94312MCG) using Main
and Auxiliary antennas for transmission in the IEEE 802.11 b/g
transmission mode, radio frequency energy is not emitted
simultaneously from both Main and Auxiliary antennas. One of
the antennas is selected automatically or manually (by users) to
have good quality of radiocommunication (transmission
diversity function). For WLAN card (Model: 512AN_MMW,
512ANXMMW) in the IEEE 802.11 a/b/g, or MIMO ( Multiple
In Multiple Out ) transmission mode, the radio frequency
energy is emitted from Main antenna.
ii) FCC ID of wireless module:
There is no FCC ID for Mini PCI Express Card shown on the enclosure of
your Lenovo computer. Instead you will find an indicator label pointing to
the location of the FCC ID on the bottom side of your Lenovo computer.
This label will be of the format “Contains Transmitter Module: FCC ID:
XXXX”, where XXXX represents the FCC ID that corresponds to your
preinstalled Wireless LAN/WiMAX module.
iii) Radio Frequency interference requirements:
• The devices have been tested and found to comply with the limits
for a Class B digital device pursuant to FCC Part 15 Subpart B. The
model BCM94312MCG was subject to DoC. Refer to “Electronic
emission notices” on page 12. The model 512AN_MMW,
512ANXMMW underwent the certification process with its FCC ID
number listed in “I. Factory preinstalled Wireless LAN/WiMAX
module” on page 2.
