Lenovo B475 Notebook - Manuel (Page 2)

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 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.
Note: The transmission diversity function is implemented for this product.
For WLAN card (Model: AR5B95, AR5B97, 622ANXHMW, 612BNXHMW,
BCM943227HM4L, 112BNHMW, BCM94313HMG2L-IPA) 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, AR5B97, 622ANXHMW, 612BNXHMW, BCM943227HM4L,
112BNHMW, BCM94313HMG2L-IPA 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.
ii) FCC ID of wireless module
There is no FCC ID for Mini PCI Express Card shown on the enclosure of your
Lenovo computer. Instead you will find an indicator label pointing to the location
of the FCC ID on the bottom side of your Lenovo computer. This label will be 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. The model BCM94312MCG
was subject to DoC. Refer to “Electronic emission notices” on page 6 . The
models AR5B95, AR5B97, 622ANXHMW, 612BNXHMW, BCM943227HM4L,
112BNHMW, BCM94313HMG2L-IPA 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.
