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/WiMax module.
iii) Radio Frequency interference requirement:
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. Refer to “Electronic emission notices” on page 4. The models
612BNXHMW, 2200BNHMW, 2230BNHMW, BCM92070MD_REF, BCM94313HMGB,
BCM94313HMG2L, AR5B125, AR5B225 underwent the certification process with each respective
FCC ID number listed in “I. Factory preinstalled Wireless LAN/WiMAX module” on page 1.
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.
Note: The transmission diversity function is implemented for this product. For WLAN cards (Model:
612BNXHMW, 2200BNHMW, 2230BNHMW, BCM92070MD_REF, BCM94313HMGB,
BCM94313HMG2L, AR5B125, AR5B225) 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 612BNXHMW, 2200BNHMW, 2230BNHMW, BCM92070MD_REF,
BCM94313HMGB, BCM94313HMG2L, AR5B125, AR5B225 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.
