i) The FCC RF Exposure compliance:
The radiated output power of the Wireless LAN/WiMAX Mini PCI Express 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:
Caution: To comply with FCC RF exposure compliance requirements, a separation distance
of at least 20 cm (8 inches) must be maintained between the antennas for the integrated
Wireless LAN/WiMAX Mini PCI Express Cards built into the screen section and all
persons. You are not allowed to disable “sleep (standby) mode” for the power management
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, 622ANXHMW, 612BNXHMW, RT3090, 112BNHMW,
BCM94313HMG2L underwent the certification process with each respective FCC ID
number listed in “I. Factory preinstalled Wireless LAN/WiMAX module” on page 1.
• Each device is restricted to indoor use due to its operation in the 5.15 to 5.25 GHz frequency
range. FCC requires these products to be used indoors for the frequency range 5.15 to
5.25 GHz to reduce the potential for harmful interference to co-channel Mobile Satellite
systems.
• High power radar are allocated as primary users of the 5.25 to 5.35 GHz and 5.65 to
5.85 GHz bands. These radar stations can cause interference with and/or damage this
device.
II. Preinstalled integrated Bluetooth module
• FCC ID: QDS-BRCM1043 (Model: BCM92070MD_REF)
Note: The transmission diversity function is implemented for this product. For WLAN card (Model:
AR5B95, 622ANXHMW, 612BNXHMW, 112BNHMW, BCM94313HMG2L, VQF-RT3090-1T1R)
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,
622ANXHMW, 612BNXHMW, 112BNHMW, BCM94313HMG2L, VQF-RT3090-1T1R 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.
