function, if you cannot maintain the sufficient antenna separation (at least 20 cm) in any
case the LCD is left opened or closed.
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
5. The models AR5B95, BCM94313HMG2L underwent the certification process with each
respective FCC ID number listed in “I. Factory preinstalled Wireless LAN/WiMAX
module” on page 1.
II. Preinstalled integrated Bluetooth module
• FCC ID: QDS-BRCM1043 (Model: BCM92070MD_REF)
i) FCC ID and installation of the module:
If you find an indication “Contains Transmitter Module: FCC ID: QDS-BRCM1043 on the
label at the bottom side of your computer, your computer contains the Bluetooth transmitter
module (Model: BCM92070MD_REF). 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:
QDS-BRCM1043 of this device includes both certifications of Part 15 Subpart B and C/E.
Note: The transmission diversity function is implemented for this product. For WLAN card (Model:
AR5B95, BCM94313HMG2L) 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 AR5B95, BCM94313HMG2L 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.
