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)
• FCC ID: VV7-MBMH5321 (Model: N5321)
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:
Note: The transmission diversity function is implemented for this product. For WLAN card (Model:
BCM943228HMB, AR5B22, N5321) 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, N5321 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.
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, N5321 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.
