Lenovo B570 Notebook - Manuel (Page 5)

Wireless LAN Mini PCI Express Cards marketed in the USA and Canada do not
support nor function in the extended channels (12ch, 13ch).
There is no certification number of Industry Canada 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 IC Certification number on the
bottom side of your Lenovo computer. This label will be of the format “Contains
Transmitter Module: Canada IC: XXXX”, where XXXX represents the IC ID that
corresponds to your preinstalled WLAN module.
II) Preinstalled integrated Bluetooth module
• IC: 4324A-BRCM1043 (Model: BCM92070MD_REF)
If you find an indication “Contains Transmitter Module: Canada IC:
4324A-BRCM1043” on the label at the bottom side of your computer, your
computer integrates the Bluetooth transmitter module. The Bluetooth module is
preinstalled by Lenovo, and is not removable by users.
III) Low power license-exempt radiocommunication devices
(RSS-210)
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference, including interference that may
cause undesired operation of the device.
The transmitter devices have been designed to operate with the antennas
integrated in the computer, and having a maximum gain of within 3 dBi.
The maximum antenna gain permitted for devices in the 5250-5350 MHz,
5470-5725 MHz, and 5725-5825 MHz bands complies with the e.i.r.p. limit in
section A9.2 of RSS-210.
IV) Exposure of humans to RF fields (RSS-102)
Lenovo computers employ low gain integral antennas that do not emit RF field in
excess of Health Canada limits for the general population; consult Safety Code 6,
obtainable from Health Canada’s Web site at:
www.hc-sc.gc.ca
The radiated energy from the antennas connected to the wireless adapters
conforms to the IC limit of the RF exposure requirement regarding IC RSS-102,
Issue 2 clause 4.2.
