USA — Federal Communications Commission (FCC) 
I. Factory preinstalled Wireless LAN and Bluetooth Combo module 
•  FCC ID: QDS-BRCM1058 (Model: BCM943228HMB)
•  FCC ID: PPD-AR5B22 (Model: AR5B22)
Wireless LAN and Bluetooth Combo Card marketed in the USA and Canada do not support 
nor function in the extended channels (12ch, 13ch). 
i) The FCC RF Exposure compliance:
The radiated output power of the Wireless LAN and Bluetooth Combo Card authorized to 
use for the your Lenovo computer is far below the FCC radio frequency exposure limits. 
Nevertheless, it shall be used in such a manner that the potential for human contact during 
normal operation is minimized as follows:
ii) FCC ID of wireless module: 
On the bottom side of your Lenovo computer, you will find an indicator label of the format 
“Contains Transmitter Module: FCC ID XXXX”, where XXXX represents the FCC ID that 
corresponds to your preinstalled Wireless LAN and Bluetooth Combo module. 
II. Simultaneous use of RF transmitters
Please make sure of the following conditions on use of wireless features:
1. When you use any other RF option device, all wireless features in your Lenovo computer 
are required to be turned off.
2. Users must follow the RF Safety instructions on wireless option devices that are included 
in the RF option device's user's manual.
III. Radio Frequency interference requirements:
Each device has been tested and found to comply with the limits for a Class B digital device 
pursuant to FCC Part 15 Subpart B. Refer to “Electronic emission notices” on page 5. 
The models BCM943228HMB, AR5B22 underwent the certification process with each 
respective FCC ID number listed in “I. Factory preinstalled Wireless LAN and Bluetooth 
Combo module” on page 2.
When you use a Wireless LAN and Bluetooth Combo module in the 802.11 a/n transmission mode:
• Each device is restricted to indoor use due to its operation in the 5150 to 5250 MHz 
frequency range. FCC requires these products to be used indoors for the frequency range 
5150 to 5250 MHz to reduce the potential for harmful interference to co-channel Mobile 
Satellite systems.
• High power radars are allocated as primary users of the 5250 to 5350 MHz and 5650 to 
5850 MHz bands. These radar stations can cause interference with and/or damage this 
device.
Note: The transmission diversity function is implemented for this product. For WLAN card (Model: 
BCM943228HMB, AR5B22) using Main and Auxiliary antennas for transmission in the IEEE 
802.11 a/g/n 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 BCM943228HMB, AR5B22 in the IEEE 802.11 a/g/n, or MIMO (Multiple In 
Multiple Out ) transmission mode, the radio frequency energy is emitted from Main antenna.
