Any changes or modifications not expressly approved by the party responsible for 
compliance could void the user’s authority to operate the equipment. 
 
CAUTION: (this only applicable to 5GHz device) 
This device is restricted to indoor use due to its operation in the 5.15 to 5.25 GHz 
frequency range. FCC requires this product to be used indoors for frequency range 5.15 
to 5.25 GHz to reduce the potential for harmful interference to co-channel Mobile 
Satellite systems. 
High power radars 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. 
 
System integrators must include the FCC ID on the end product.  
 
FCC Radio-Frequency Exposure & Approval Conditions: 
1. For mobile applications: 
Antennas must be installed in the display section of Netbook/notebook/laptop computer 
to provide at least 20cm separation distance from the transmitting antenna to the body of 
user during normal operating condition.
 
For portable applications:  
-Antennas must be installed in the display section or underneath the keyboard in 
Netbook/notebook/laptop computers to provide at least 5mm separation distance from the 
transmitting antenna to the body of user , or any other person during normal operating 
condition. Configuration in tablets must be with at least 10mm antenna-to-enclosure 
separation distance.  
 
-The WLAN antennas used must be the same antennas as in this filing. The distance 
between two antennas (Chain 1 and Chain 2) is 5cm. 
 
- For standalone SAR testing, the antenna is mounted on lossless foam material for 
testing. In order to use Broadcom modular approval, PC–OEMs must install antennas 
with non–conductive materials surrounding the antenna.  
 
2. The antenna(s) used for this transmitter must not be collocated or operating in 
conjunction with any other antenna or transmitter within a host device, except in 
accordance with FCC multi-transmitter product procedures. 
 
3. The regulatory label on the final system must include the statement: “Contains FCC 
ID: QDS-BRCM1084 “or using electronic labeling method as documented in KDB 
784748.
