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 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. Refer
to “Electronic emission notices” on page 10. The models AR5B95,
BCM94313HMG2L, 112BNHMW, 622ANHMW, 622ANXHMW,
BCM94313HMGB, BCM943225HMB, AR5B195, AR5B197
underwent the certification process with each respective FCC ID
number listed in “I. Factory preinstalled Wireless LAN/WiMAX
module” on page 2.
Note: The transmission diversity function is implemented for this product. For
WLAN card (Model: 112BNHMW, AR5B95, BCM94313HMG2L,
BCM94313HMGB, BCM943225HMB, AR5B195, AR5B197) 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 (112BNHMW, AR5B95, BCM94313HMG2L,
BCM94313HMGB, BCM943225HMB, AR5B195, AR5B197, 622ANHMW,
622ANXHMW) 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.
