iii) FCC RF Exposure compliance
The radiated output power of the PCI Express Mini Card authorized to use for your
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 connected to the PCI Express Mini Cards and all persons. If the
distance may not be maintained while the computer is closed, you must
select sleep (standby) as the power mode when closing the display.
Note: The transmission diversity function is implemented for this product.
For WLAN card (Model: 2230BNHMW, BCM94313HMGB, BCM943228HMB,
62205ANHMW, RTL8188CE, and 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 2230BNHMW, BCM94313HMGB, BCM943228HMB, 62205ANHMW,
RTL8188CE, and 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.
iv) Radio Frequency interference requirements
Each device has 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 7.
When you use a wireless LAN adapter in the 802.11 a/n transmission mode:
• Each device is restricted to indoor use due to its operation in the 5150 to 5250
MHz frequency range. FCC requires these products to be used indoors for
the frequency range 5150 to 5250 MHz to reduce the potential for harmful
interference to co-channel Mobile Satellite systems.
• High power radars are allocated as primary users of the 5250 to 5350 MHz and
5650 to 5850 MHz bands. These radar stations can cause interference with
and/or damage this device.
III. Simultaneous use of RF transmitters
Your computer is approved for simultaneous use of one of the approved wireless
LAN adapters, the approved wireless WAN adapter, and the approved Bluetooth
device. For a list of those transmitters, refer to “I. Approved wireless devices”
on page 2.
