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 cards
(Model: 512AN_MMW, 512ANXMMW, 533AN_MMW*) 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 70. The models 512AN_MMW,
512ANXMMW, 533AN_MMW* underwent the certification process with each respective
FCC ID number listed in "I. Factory preinstalled Wireless LAN/WiMAX module" on
page 66.
• Each device is restricted to indoor use due to its operation in the 5.15 to 5.25 GHz frequency
range. FCC requires these products to be used indoors for the frequency range 5.15 to
5.25 GHz to reduce the potential for harmful interference to co-channel Mobile Satellite
systems.
• High power radar are allocated as primary users of the 5.25 to 5.35 GHz and 5.65 to
5.85 GHz bands. These radar stations can cause interference with and/or damage this
device.
II. Preinstalled integrated Bluetooth module
• FCC ID: MCLBCM92046 (Model: BCM92046)
i) FCC ID and installation of the module:
If you find an indication "Contains Transmitter Module: FCC ID: MCLBCM92046" on the
label at the bottom side of your computer, your computer contains the Bluetooth transmitter
module (Model: BCM92046). The Bluetooth module is preinstalled by Lenovo, and is not
removable by users.
ii) The FCC RF safety requirement:
The radiated output power of the Bluetooth module is far below the FCC radio frequency
exposure limits. Therefore, a 20 cm of separation between the Bluetooth antenna and human
body is not required.
iii) Radio Frequency interference requirements:
The device has been tested and found to comply with the limits for both a Class B digital
device regarding FCC Part 15 Subpart B and an intentional radiator regarding FCC Part 15
Subpart C; then it underwent the certification processes for both rules. Thus the FCC ID
MCLBCM92046 of this device includes both certifications of Part 15 Subpart B and C.
